NOTE: Products with CE marks perform their required functions safely and adhere to relevant standards as
specified by CE directives, provided they are used according to their intended purpose and that the
instructions in this manual are adhered to. The protection provided by the equipment may be impaired if
this equipment is used in a manner not specified in this manual. A listing of our international affiliates is
available on our Web site: http://www.automationdirect.com
WARNING: Providing a safe operating environment for personnel and equipment is your responsibility
and should be your primary goal during system planning and installation. Automation systems can fail
and may result in situations that can cause serious injury to personnel and/or damage equipment. Do
not rely on the automation system alone to provide a safe operating environment. Sufficient emergency
circuits should be provided to stop either partially or totally the operation of the PLC or the controlled
machine or process. These circuits should be routed outside the PLC in the event of controller failure,
so that independent and rapid shutdown are available. Devices, such as “mushroom” switches or end
of travel limit switches, should operate motor starter, solenoids, or other devices without being
processed by the PLC. These emergency circuits should be designed using simple logic with a
minimum number of highly reliable electromechanical components. Every automation application is
different, so there may be special requirements for your particular application. Make sure all national,
state, and local government requirements are followed for the proper installation and use of your
equipment.
Plan for Safety
The best way to provide a safe operating environment is to make personnel and equipment
safety part of the planning process. You should examine every aspect of the system to
determine which areas are critical to operator or machine safety.
If you are not familiar with PLC system installation practices, or your company does not have
established installation guidelines, you should obtain additional information from the
following sources.
• NEMA — The National Electrical Manufacturers Association, located in Washington,
D.C., publishes many different documents that discuss standards for industrial control
systems. You can order these publications directly from NEMA. Some of these include:
ICS 1, General Standards for Industrial Control and Systems
ICS 3, Industrial Systems
ICS 6, Enclosures for Industrial Control Systems
• NEC — The National Electrical Code provides regulations concerning the installation and
use of various types of electrical equipment. Copies of the NEC Handbook can often be
obtained from your local electrical equipment distributor or your local library.
• Local and State Agencies — many local governments and state governments have additional
requirements above and beyond those described in the NEC Handbook. Check with your
local Electrical Inspector or Fire Marshall office for information.

Chapter 2: Installation, Wiring and Specifications
Three Levels of Protection
The publications mentioned provide many ideas and requirements for system safety. At a
minimum, you should follow these regulations. Also, you should use the following
techniques, which provide three levels of system control.
• Emergency stop switch for disconnecting system power
• Mechanical disconnect for output module power
• Orderly system shutdown sequence in the PLC control program
Emergency Stops
It is recommended that emergency stop circuits be incorporated into the system for every
machine controlled by a PLC. For maximum safety in a PLC system, these circuits must not
be wired into the controller, but should be hardwired external to the PLC. The emergency
stop switches should be easily accessed by the operator and are generally wired into a master
control relay (MCR) or a safety control relay (SCR) that will remove power from the PLC
I/O system in an emergency.
MCRs and SCRs provide a convenient means for removing power from the I/O system
during an emergency situation. By de-energizing an MCR (or SCR) coil, power to the input
(optional) and output devices is removed. This event occurs when any emergency stop switch
opens. However, the PLC continues to receive power and operate even though all its inputs
and outputs are disabled.
The MCR circuit could be extended by placing a PLC fault relay (closed during normal PLC
operation) in series with any other emergency stop conditions. This would cause the MCR
circuit to drop the PLC I/O power in case of a PLC failure (memory error, I/O
communications error, etc.).

Emergency Power Disconnect
A properly rated emergency power disconnect should be used to power the PLC controlled
system as a means of removing the power from the entire control system. It may be necessary
to install a capacitor across the disconnect to protect against a condition known as “outrush”.
This condition occurs when the output Triacs are turned off by powering off the disconnect,
thus causing the energy stored in the inductive loads to seek the shortest distance to ground,
which is often through the Triacs.
After an emergency shutdown or any other type of power interruption, there may be
requirements that must be met before the PLC control program can be restarted. For
example, there may be specific register values that must be established (or maintained from
the state prior to the shutdown) before operations can resume. In this case, you may want to
use retentive memory locations, or include constants in the control program to insure a
known starting point.
Orderly System Shutdown
Ideally, the first level of fault detection is the PLC control
program, which can identify machine problems. Certain
shutdown sequences should be performed. The types of
problems are usually things such as jammed parts, etc.
that do not pose a risk of personal injury or equipment
damage.
WARNING: The control program must not be the only form of
protection for any problems that may result in a risk of personal
injury or equipment damage.

Mounting Guidelines
Before installing the PLC system you will need to know the dimensions of the components
considered. The diagrams on the following pages provide the component dimensions to use
in defining your enclosure specifications. Remember to leave room for potential expansion.
NOTE: If you are using other components in your system, refer to the appropriate manual to determine
how those units can affect mounting dimensions.
Base Dimensions
The following information shows the proper mounting dimensions. The height dimension is
the same for all bases. The depth varies depending on your choice of I/O module. The length
varies as the number of slots increase. Make sure you have followed the installation guidelines
for proper spacing.

Panel Mounting and Layout
It is important to design your panel properly to help ensure the DL205 products operate
within their environmental and electrical limits. The system installation should comply with
all appropriate electrical codes and standards. It is important the system also conforms to the
operating standards for the application to insure proper performance. The diagrams below
reference the items in the following list.
OK
Airflow
1. Mount the bases horizontally to provide proper ventilation.
2. If you place more than one base in a cabinet, there should be a minimum of 7.2” (183mm)
between bases.
3. Provide a minimum clearance of 2” (50mm) between the base and all sides of the cabinet. There
should also be at least 1.2” (30mm) of clearance between the base and any wiring ducts.
4. There must be a minimum of 2” (50mm) clearance between the panel door and the nearest DL205
component.
NOTE: The cabinet configuration below is not suitable for EU installations.

5. The ground terminal on the DL205 base must be connected to a single point ground. Use copper
stranded wire to achieve a low impedance. Copper eye lugs should be crimped and soldered to the
ends of the stranded wire to ensure good surface contact. Remove anodized finishes and use copper
lugs and star washers at termination points. A general rule is to achieve a 0.1 ohm of DC resistance
between the DL205 base and the single point ground.
6. There must be a single point ground (i.e. copper bus bar) for all devices in the panel requiring an
earth ground return. The single point of ground must be connected to the panel ground
termination. The panel ground termination must be connected to earth ground. For this
connection you should use #12 AWG stranded copper wire as a minimum. Minimum wire sizes,
color coding, and general safety practices should comply with appropriate electrical codes and
standards for your region. A good common ground reference (Earth ground) is essential for proper
operation of the DL205. There are several methods of providing an adequate common ground
reference, including:
a) Installing a ground rod as close to the panel as possible.
b) Connection to incoming power system ground.
7. Properly evaluate any installations where the ambient temperature may approach the lower or
upper limits of the specifications. Place a temperature probe in the panel, close the door and
operate the system until the ambient temperature has stabilized. If the ambient temperature is not
within the operating specification for the DL205 system, measures such as installing a
cooling/heating source must be taken to get the ambient temperature within the DL205 operating
specifications.
8. Device mounting bolts and ground braid termination bolts should be #10 copper bolts or
equivalent. Tapped holes instead of nut–bolt arrangements should be used whenever possible. To
ensure good contact on termination areas impediments such as paint, coating or corrosion should
be removed in the area of contact.
9. The DL205 system is designed to be powered by 110/220 VAC, 24 VDC, or 125 VDC normally
available throughout an industrial environment. Electrical power in some areas where the PLCs are
installed is not always stable and storms can cause power surges. Due to this, powerline filters are
recommended for protecting the DL205 PLCs from power surges and EMI/RFI noise. The
Automation Powerline Filter, for use with 120 VAC and 240 VAC, 1–5 Amps, is an excellent
choice (can be located at www.automationdirect.com), however, you can use a filter of your choice.
These units install easily between the power source and the PLC.
Enclosures
Your selection of a proper enclosure is important to ensure safe and proper operation of your
DL205 system. Applications of DL205 systems vary and may require additional features. The
minimum considerations for enclosures include:
• Conformance to electrical standards
• Protection from the elements in an industrial environment
• Common ground reference
• Maintenance of specified ambient temperature
• Access to equipment
• Security or restricted access
• Sufficient space for proper installation and maintenance of equipment

I/O Slots
Your choice of base depends on three things:
• Number of I/O modules required
• Input power requirement (AC or DC power)
• Available power budget
Mounting the Base
All I/O configurations of the DL205 may use any of the base configurations. The bases are
secured to the equipment panel or mounting location using four M4 screws in the corner tabs
of the base. The full mounting dimensions are given in the previous section on Mounting
Guidelines.

Chapter 2: Installation, Wiring and Specifications
Using Mounting Rails
The DL205 bases can also be secured to the cabinet by using mounting rails. You should use
rails that conform to DIN EN standard 50 022. Refer to our catalog for a complete line of
DIN rail, DINnectors and DIN rail mounted apparatus. These rails are approximately 35mm
high, with a depth of 7.5mm. If you mount the base on a rail, you should also consider using
end brackets on each end of the rail. The end brackets help keep the base from sliding
horizontally along the rail. This helps minimize the possibility of accidentally pulling the
wiring loose.
If you examine the bottom of the base, you’ll notice small retaining clips. To secure the base
to a DIN rail, place the base onto the rail and gently push up on the retaining clips. The clips
lock the base onto the rail.
To remove the base, pull down on the retaining clips, lift up on the base slightly, and pull it
away from the rail.

I/O Wiring Strategies
2–14
The DL205 PLC system is very flexible and will work in many different wiring
configurations. By studying this section before actual installation, you can probably find the
best wiring strategy for your application. This will help to lower system cost, wiring errors,
and avoid safety problems.
PLC Isolation Boundaries
PLC circuitry is divided into three main regions separated by isolation boundaries, shown in
the drawing below. Electrical isolation provides safety, so that a fault in one area does not
damage another. A powerline filter will provide isolation between the power source and the
power supply. A transformer in the power supply provides magnetic isolation between the
primary and secondary sides. Opto-couplers provide optical isolation in Input and Output
circuits. This isolates logic circuitry from the field side, where factory machinery connects.
Note the discrete inputs are isolated from the discrete outputs, because each is isolated from
the logic side. Isolation boundaries protect the operator interface (and the operator) from
power input faults or field wiring faults. When wiring a PLC, it is extremely important to
avoid making external connections that connect logic side circuits to any other.

Powering I/O Circuits with the Auxiliary Supply
In some cases, using the built-in auxiliary +24VDC supply can result in a cost savings for
your control system. It can power combined loads up to 300mA. Be careful not to exceed the
current rating of the supply. If you are the system designer for your application, you may be
able to select and design in field devices which can use the +24VDC auxiliary supply.
All AC powered and 125VDC DL205 bases feature the internal auxiliary supply. If input
devices AND output loads need +24VDC power, the auxiliary supply may be able to power
both circuits as shown in the following diagram.

The 12/24VDC powered DL205 bases are designed for application environments in which
low-voltage DC power is more readily available than AC. These include a wide range of
battery–powered applications, such as remotely-located control, in vehicles, portable
machines, etc. For this application type, all input devices and output loads typically use the
same DC power source. Typical wiring for DC-powered applications is shown in the

Powering I/O Circuits Using Separate Supplies
In most applications it will be necessary to power the input devices from one power source,
and to power output loads from another source. Loads often require high-energy AC power,
while input sensors use low-energy DC. If a machine operator is likely to come in close
contact with input wiring, then safety reasons also require isolation from high-energy output
circuits. It is most convenient if the loads can use the same power source as the PLC, and the
input sensors can use the auxiliary supply, as shown to the left in the figure below.
If the loads cannot be powered from the PLC supply, then a separate supply must be used as
shown to the right in the figure below.

Some applications will use the PLC external power source to also power the input circuit.
This typically occurs on DC-powered PLCs, as shown in the drawing below to the left. The
inputs share the PLC power source supply, while the outputs have their own separate supply.
A worst-case scenario, from a cost and complexity viewpoint, is an application which requires
separate power sources for the PLC, input devices, and output loads. The example wiring
diagram below on the right shows how this can work, but also the auxiliary supply output is
an unused resource. You will want to avoid this situation if possible.

Sinking / Sourcing Concepts
Before going further in the study of wiring strategies, you must have a solid understanding of
“sinking” and “sourcing” concepts. Use of these terms occurs frequently in input or output
circuit discussions. It is the goal of this section to make these concepts easy to understand,
further ensuring your success in installation. First the following short definitions are provided,
followed by practical applications.
Sinking = provides a path to supply ground (–)
Sourcing = provides a path to supply source (+)
First you will notice these are only associated with DC circuits and not AC, because of the
reference to (+) and (–) polarities. Therefore, sinking and sourcing terminology only applies
to DC input and output circuits. Input and output points that are sinking only or sourcing
only can conduct current in only one direction. This means it is possible to connect the
external supply and field device to the I/O point with current trying to flow in the wrong
direction, and the circuit will not operate. However, you can successfully connect the supply
and field device every time by understanding “sourcing” and “sinking”.
For example, the figure to the right depicts a “sinking”
PLC
input. To properly connect the external supply, you
Input
will have to connect it so the input provides a path to
(sinking)
ground (–). Start at the PLC input terminal, follow
+
through the input sensing circuit, exit at the common
Input
Sensing
terminal, and connect the supply (–) to the common
–
terminal. By adding the switch, between the supply (+)
Common
and the input, the circuit has been completed .
Current flows in the direction of the arrow when the
switch is closed.
Apply the circuit principle above to the four possible combinations of input/output
sinking/sourcing types as shown below. The I/O module specifications at the end of this
chapter list the input or output type.

I/O “Common” Terminal Concepts
In order for a PLC I/O circuit to operate,
current must enter at one terminal and exit
at another. Therefore, at least two terminals
are associated with every I/O point. In the
figure to the right, the Input or Output
terminal is the main path for the current.
One additional terminal must provide the
return path to the power supply.

If there was unlimited space and budget for
I/O terminals, every I/O point could have
two dedicated terminals as the figure above
shows. However, providing this level of
flexibility is not practical or even necessary
for most applications. So, most Input or
Output points on PLCs are in groups which
share the return path (called commons). The
figure to the right shows a group (or bank) of
four input points which share a common
return path. In this way, the four inputs
require only five terminals instead of eight.

Common
NOTE: In the circuit above, the current in the common path is 4 times any channel’s input current when all
inputs are energized. This is especially important in output circuits, where heavier gauge wire is
sometimes necessary on commons.
Most DL205 input and output modules group their I/O
points into banks that share a common return path.
The best indication of I/O common grouping is on the
wiring label, such as the one shown to the right. There
are two circuit banks with eight input points in each.
The common terminal for each is labeled “CA” and
“CB”, respectively.
In the wiring label example, the positive terminal of a
DC supply connects to the common terminals. Some
symbols you will see on the wiring labels, and their
meanings are:

Connecting DC I/O to “Solid State” Field Devices
In the previous section on Sourcing and Sinking concepts, the DC I/O circuits were
explained to sometimes only allow current to flow one way. This is also true for many of the
field devices which have solid-state (transistor) interfaces. In other words, field devices can
also be sourcing or sinking. When connecting two devices in a series DC circuit, one must be
wired as sourcing and the other as sinking.
Solid State Input Sensors
Several DL205 DC input modules are flexible because they detect current flow in either
direction, so they can be wired as either sourcing or sinking. In the following circuit, a field
device has an open-collector NPN transistor output. It sinks current from the PLC input
point, which sources current. The power supply can be the +24 auxiliary supply or another
supply (+12 VDC or +24VDC), as long as the input specifications are met.

In the next circuit, a field device has an open-collector PNP transistor output. It sources
current to the PLC input point, which sinks the current back to ground. Since the field
device is sourcing current, no additional power supply is required.

Solid State Output Loads
Sometimes an application requires connecting a PLC output point to a solid state input on a
device. This type of connection is usually made to carry a low-level control signal, not to send
DC power to an actuator.
Several of the DL205 DC output modules are the sinking type. This means that each DC
output provides a path to ground when it is energized. In the following circuit, the PLC
output point sinks current to the output common when energized. It is connected to a
sourcing input of a field device input.

In the next example a PLC sinking DC output point is connected to the sinking input of a
field device. This is a little tricky, because both the PLC output and field device input are
sinking type. Since the circuit must have one sourcing and one sinking device, a sourcing
capability needs to be added to the PLC output by using a pull-up resistor. In the circuit
below, a Rpull-up is connected from the output to the DC output circuit power input.

NOTE 1: DO NOT attempt to drive a heavy load (>25 mA) with this pull-up method
NOTE 2: Using the pull-up resistor to implement a sourcing output has the effect of inverting the output
point logic. In other words, the field device input is energized when the PLC output is OFF, from a ladder
logic point of view. Your ladder program must comprehend this and generate an inverted output. Or, you
may choose to cancel the effect of the inversion elsewhere, such as in the field device.
It is important to choose the correct value of Rpull-up. In order to do so, you need to know
the nominal input current to the field device (Iinput) when the input is energized. If this value
is not known, it can be calculated as shown (a typical value is 15 mA). Then use Iinput and
the voltage of the external supply to compute Rpull-up. Then calculate the power Ppull-up (in
watts), in order to size Rpull-up properly.

Of course, the easiest way to drive a sinking input field device as shown below is to use a DC

Relay Output Guidelines
Several output modules in the DL205 I/O family feature relay outputs: D2–04TRS,
D2–08TR, D2–12TR, D2–08CDR, F2–08TR and F2–08TRS. Relays are best for the
following applications:
• Loads that require higher currents than the solid-state outputs can deliver
• Cost-sensitive applications
• Some output channels need isolation from other outputs (such as when some loads require different
voltages than other loads)
Some applications in which NOT to use relays:
• Loads that require currents under 10 mA
• Loads which must be switched at high speed or heavy duty cycle
Relay with Form A contacts
Relay outputs in the DL205 output modules are available in
two contact arrangements, shown to the right. The Form A
type, or SPST (single pole, single throw) type is normally open
and is the simplest to use. The Form C type, or SPDT (single
pole, double throw) type has a center contact which moves and
a stationary contact on either side. This provides a normally
closed contact and a normally open contact.
Some relay output module’s relays share common terminals,
which connect to the wiper contact in each relay of the bank.
Other relay modules have relays which are completely isolated
from each other. In all cases, the module drives the relay coil
when the corresponding output point is on.

Relay Outputs – Transient Suppression for Inductive Loads in a Control System
The following pages are intended to give a quick overview of the negative effects of transient
voltages on a control system and provide some simple advice on how to effectively minimize
them. The need for transient suppression is often not apparent to the newcomers in the
automation world. Many mysterious errors that can afflict an installation can be traced back to
a lack of transient suppression.
What is a Transient Voltage and Why is it Bad?
Inductive loads (devices with a coil) generate transient voltages as they transition from being
energized to being de-energized. If not suppressed, the transient can be many times greater than
the voltage applied to the coil. These transient voltages can damage PLC outputs or other
electronic devices connected to the circuit, and cause unreliable operation of other electronics
in the general area. Transients must be managed with suppressors for long component life and
reliable operation of the control system.
This example shows a simple circuit with a small 24V/125mA/3W relay. As you can see, when
the switch is opened, thereby de-energizing the coil, the transient voltage generated across the
switch contacts peaks at 140V.

In the same circuit, replacing the relay with a larger 24V/290mA/7W relay will generate a
transient voltage exceeding 800V (not shown). Transient voltages like this can cause many
problems, including:
• Relay contacts driving the coil may experience arcing, which can pit the contacts and reduce the
relay's lifespan.
• Solid state (transistor) outputs driving the coil can be damaged if the transient voltage exceeds the
transistor's ratings. In extreme cases, complete failure of the output can occur the very first time a
coil is de-energized.
• Input circuits, which might be connected to monitor the coil or the output driver, can also be
damaged by the transient voltage.
A very destructive side-effect of the arcing across relay contacts is the electromagnetic
interference (EMI) it can cause. This occurs because the arcing causes a current surge, which
releases RF energy. The entire length of wire between the relay contacts, the coil, and the power
source carries the current surge and becomes an antenna that radiates the RF energy. It will
readily couple into parallel wiring and may disrupt the PLC and other electronics in the area.
This EMI can make an otherwise stable control system behave unpredictably at times.
PLC's Integrated Transient Suppressors
Although the PLC's outputs typically have integrated suppressors to protect against transients,
they are not capable of handling them all. It is usually necessary to have some additional
transient suppression for an inductive load.
The next example uses the same 24V/125mA/3W relay used earlier. This example measures the
PNP transistor output of a D0-06DD2 PLC, which incorporates an integrated Zener diode for
transient suppression. Instead of the 140V peak in the first example, the transient voltage here
is limited to about 40V by the Zener diode. While the PLC will probably tolerate repeated
transients in this range for some time, the 40V is still beyond the module's peak output voltage
rating of 30V.

The next example uses the same circuit as above, but with a larger 24V/290mA/7W relay,
thereby creating a larger inductive load. As you can see, the transient voltage generated is much
worse, peaking at over 50V. Driving an inductive load of this size without additional transient
suppression is very likely to permanently damage the PLC output.

Additional transient suppression should be used in both these examples. If you are unable to
measure the transients generated by the connected loads of your control system, using
additional transient suppression on all inductive loads would be the safest practice.

Two more common options for DC coils are Metal Oxide Varistors (MOV) or TVS diodes.
These devices should be connected across the driver (PLC output) for best protection as shown
below. The optimum voltage rating for the suppressor is the lowest rated voltage available that
will NOT conduct at the supply voltage, while allowing a safe margin.
AutomationDirect's ZL-TSD8-24 transorb module is a good choice for 24VDC circuits. It is
a bank of 8 uni-directional 30V TVS diodes. Since they are uni-directional, be sure to observe
the polarity during installation. MOVs or bi-directional TVS diodes would install at the same
location, but have no polarity concerns.

AC Coils:
Two options for AC coils are MOVs or bi-directional TVS diodes. These devices are most
effective at protecting the driver from a transient voltage when connected across the driver (PLC
output) but are also commonly connected across the coil. The optimum voltage rating for the
suppressor is the lowest rated voltage available that will NOT conduct at the supply voltage,
while allowing a safe margin.
AutomationDirect's ZL-TSD8-120 transorb module is a good choice for 120VAC circuits. It
is a bank of eight bi-directional 180V TVS diodes.
AC MOV or Bi-Directional Diode Circuit
VAC
NOTE: Manufacturers of devices with coils frequently offer MOV or TVS diode suppressors as an add-on
option which mount conveniently across the coil. Before using them, carefully check the suppressor's
ratings. Just because the suppressor is made specifically for that part does not mean it will reduce the
transient voltages to an acceptable level.
For example, a MOV or TVS diode rated for use on 24-48 VDC coils would need to have a
high enough voltage rating to NOT conduct at 48V. That suppressor might typically start
conducting at roughly 60VDC. If it were mounted across a 24V coil, transients of roughly 84V
(if sinking output) or -60V (if sourcing output) could reach the PLC output. Many
semiconductor PLC outputs cannot tolerate such levels.

Slot Numbering
The DL205 bases each provide different numbers of slots for use with the I/O modules. You
may notice the bases refer to 3-slot, 4-slot, etc. One of the slots is dedicated to the CPU, so
you always have one less I/O slot. For example, you have five I/O slots with a 6-slot base. The
I/O slots are numbered 0 – 4. The CPU slot always contains a PLC CPU or other CPU–slot
controller and is not numbered.

Special Placement Considerations for Analog Modules
In most cases, the analog modules can be placed in any slot. However, the placement can also
depend on the type of CPU you are using and the other types of modules installed to the left
of the analog modules. If you’re using a DL230 CPU (or a DL240 CPU with firmware earlier
than V1.4) you should check the DL205 Analog I/O Manual for any possible placement
restrictions related to your particular module. You can order the DL205 Analog I/O Manual
by ordering part number D2–ANLG–M.

Wiring the Different Module Connectors
There are two types of module connectors for the DL205 I/O. Some modules have normal
screw terminal connectors. Other modules have connectors with recessed screws. The
recessed screws help minimize the risk of someone accidentally touching active wiring.
Both types of connectors can be easily removed. If you examine the connectors closely, you’ll
notice there are squeeze tabs on the top and bottom. To remove the terminal block, press the
squeeze tabs and pull the terminal block away from the module.
We also have DIN rail mounted terminal blocks, DINnectors (refer to our catalog for a
complete listing of all available products). ZIPLinks come with special pre–assembled cables
with the I/O connectors installed and wired.
WARNING: For some modules, field device power may still be present on the terminal block even
though the PLC system is turned off. To minimize the risk of electrical shock, check all field device
power before you remove the connector.

but it really depends on the thickness and stiffness of the wire insulation. If the insulation is too thick or
stiff and a majority of the module’s I/O points are used, then the plastic terminal cover may not close
properly or the connector may pull away from the module. This applies especially for high temperature
thermoplastics such as THHN.
2. Always use a continuous length of wire, do not combine wires to attain a needed length.
3. Use the shortest possible wire length.
4. Use wire trays for routing where possible.
5. Avoid running wires near high energy wiring. Also, avoid running input wiring close to output
wiring where possible.
6. To minimize voltage drops when wires must run a long distance , consider using multiple wires for
the return line.
7. Avoid running DC wiring in close proximity to AC wiring where possible.
8. Avoid creating sharp bends in the wires.
DINnector External Fuses
(DIN rail mounted Fuses)
Safety Guidelines
9. To reduce the risk of having a module with a blown fuse, we suggest you add external fuses to your
I/O wiring. A fast blow fuse, with a lower current rating than the I/O module fuse can be added to
each common, or a fuse with a rating of slightly less than the maximum current per output point
can be added to each output. Refer to our catalog for a complete line of DINnectors, DIN rail
mounted fuse blocks.

NOTE: For modules which have soldered or non-replaceable fuses, we recommend you return your module
to us and let us replace your blown fuse(s) since disassembling the module will void your warranty.

Find the load current you expect to use and the duration that the
output is ON. The number at the intersection of the row and column
represents the switching cycles per minute. For example, a 1A
inductive load that is on for 100 ms can be switched on and off a
maximum of 60 times per minute. To convert this to duty cycle
percentage use: (duration x cycles)/60. In this example,
(60 x .1)/60 = .1, or 10% duty cycle.

F2–16TD1(2)P, DC Output With Fault Protection
NOTE: Not supported in D2-230, D2-240
and D2-250 CPUs.
These modules detect the following fault status and
turn the related X bit(s) on.
1. Missing external 24VDC for the module
2. Open load1
3. Over temperature (the output is shut down)
4. Over load current (the output is shut down)
Fault Status
Missing external 24VDC
Open load1
Over temperature
X bit Fault Status Indication
All 16 X bits are on.
Only the X bit assigned to the
faulted output is on
Over load current
When these modules are installed, 16 X
bits are automatically assigned as the
fault status indicator. Each X bit
indicates the fault status of each output.
In this example, X10-X27 are assigned as the fault
status indicator.
X10: Fault status indicator for Y0
X11: Fault status indicator for Y1
Example
D2-250-1 or D2-260
X26: Fault status indicator for Y16
X27: Fault status indicator for Y17
Slot 0 Slot 1 Slot 2 Slot 3 Slot 4
The fault status indicators (X bits) can be reset by
performing the indicated operations in the
following table:
Fault Status
Missing external 24VDC

1) Contact life may be extended beyond those values shown with the
use of arc suppression techniques described in the DL205 User
Manual. Since these modules have no leakage current, they do not
have built-in snubber. For example, if you place a diode across a
24 VDC inductive load, you can significantly increase the life of the
relay.
2) At 120 VDC 0.5A resistive load, contact life cycle is 200k cycles.
3) Normally closed contacts have 1/2 the current handling
capability of the normally open contacts.

Glossary of Specification Terms
Inputs or Outputs Per Module
Indicates number of input or output points per module and designates current sinking,
current sourcing, or either.
Commons Per Module
Number of commons per module and their electrical characteristics.
Input Voltage Range
The operating voltage range of the input circuit.
Output Voltage Range
The operating voltage range of the output circuit.
Peak Voltage
Maximum voltage allowed for the input circuit.
AC Frequency
AC modules are designed to operate within a specific frequency range.
ON Voltage Level
The voltage level at which the input point will turn ON.
OFF Voltage Level
The voltage level at which the input point will turn OFF.
Input impedance
Input impedance can be used to calculate input current for a particular operating voltage.
Input Current
Typical operating current for an active (ON) input.
Minimum ON Current
The minimum current for the input circuit to operate reliably in the ON state.
Maximum OFF Current
The maximum current for the input circuit to operate reliably in the OFF state.
Minimum Load
The minimum load current for the output circuit to operate properly.
External DC Required
Some output modules require external power for the output circuitry.
ON Voltage Drop
Sometimes called “saturation voltage”, it is the voltage measured from an output point to its
common terminal when the output is ON at max. load.

Maximum Leakage Current
The maximum current a connected maximum load will receive when the output point is
OFF.
Maximum Inrush Current
The maximum current used by a load for a short duration upon an OFF to ON transition of
a output point. It is greater than the normal ON state current and is characteristic of
inductive loads in AC circuits.
Base Power Required
Power from the base power supply is used by the DL205 input modules and varies between
different modules. The guidelines for using module power is explained in the power budget
configuration section in Chapter 4–7.
OFF to ON Response
The time the module requires to process an OFF to ON state transition.
ON to OFF Response
The time the module requires to process an ON to OFF state transition.
Terminal Type
Indicates whether the terminal type is a removable or non-removable connector or a terminal.
Status Indicators
The LEDs that indicate the ON/OFF status of an input point. These LEDs are electrically
located on either the logic side or the field device side of the input circuit.
Weight
Indicates the weight of the module. See Appendix F for a list of the weights for the various
DL205 components.
Fuses
Protective devices for an output circuit, which stop current flow when current exceeds the
fuse rating. They may be replaceable or non–replaceable, or located externally or internally.
