2501 Installation and Operation Guide: 062-00341-010
Summary: The 2501 is designed to translate a digital word from the programmable logic controller
(PLC) into an equivalent analog voltage and/or current output signal, and to translate an analog input
signal into an equivalent digital word which is then sent to the PLC.
Configuring the Module
Using dip switches and jumpers, the 2501 must be configured for certain operating parameters, both
on a module and per-channel basis. The configuration parameters are the density mode, outputs at
power up, simulation mode, input/output scaling, digital filtering, voltage or current inputs, input
voltage range, unipolar/bipolar input mode, and output voltage range. As shipped, the jumpers are set
in the positions outlined in Figure 2.4 Shipping Jumper Configuration Locations.
Configuring the 2501 for operation consists of the following steps (notations in parenthesis are actual
printed board titles; see Figure 2.3 Jumper and Switch Locations for actual board layout):
1. Selecting Hi (HI) or Lo (LO) Density mode for the module.
2. Selecting Last Value (LAST) or Zero (ZERO) output at power up for the module.
3. Selecting the 7012 (7012) or 7016 (7016) simulation mode for the module.
4. Selecting input/output scaling (EN) or no input/output scaling (DIS) for the module.
5. Selecting digital filtering (EN) or no filtering (DIS) for the module.
6. Selecting voltage (VOLTAGE) or current (20MA) mode for each input channel.
7. Selecting 0 to 5V (5V) or 0 to 10V (10V) input voltage range for each channel.
8. Selecting unipolar (UNI) or bipolar (BI) mode for each input channel.
9. Selecting 0 to 5V (5V) or 0 to 10V (10V) output voltage range for each channel.
10. Selecting unipolar (UNI) or bipolar (BI) mode for each output channel.
11. Configuring DIP switches to report the hardware selections to the microcomputer.
12. Logging the configuration jumper settings for future reference.
Selecting Hi or Lo Density Mode
The 2501 is shipped to log in as a 12WX and 4WY module, which simulates the Siemens® 7012
mode (see Figure 2.7). This represents one of two HI density modes the 2501 is capable of handling.
The second HI mode simulates the 7016 in which there are 20WX and 4WY (see Figure 2.8). Error
codes are defined in Figure 2.5. The Low density mode exists to provide yet another alternative
input/output combination, namely an 8WX input module (see Figure 2.6). The analog outputs are not
driven and remain at zero volts/amps out.

Figure 2.8 Word Mapping for Hi Density, 7016 Simulation
Selecting Either Zero or Last Value Output at Power Up
Upon power up of the base power, the 2501 allows the user to choose between either a zero output
value or last output value when transitioning to the next update. A hardware JP37 jumper setting (see
Figure 2.3) sets the entire module for the mode chosen. The normal shipping configuration is in the
LAST VALUE mode.
Selecting Simulation Mode
Locate the Simulation Mode “SIM MODE” jumper JP3 (see Figure 2.3). To enable 7012 simulation
mode for the module set the jumper to the “7012” position. To enable the 7016 simulation mode for
the module set the jumper to the “7016” position. As shipped, the 7012 mode is enabled.
Selecting Automatic Input/Output Scaling Mode
Some applications require an Offset Input/Output Scaling Mode for 4-20mA or 1-5VDC. The PLC
can adjust a loop calculation to provide an offset scaling input/output. If the application does not use
the PID control block then the processing must be done in relay ladder logic. The 2501 can perform
this offset calculation and input or output an offset signal independent of the PLC. Selecting this
function with JP1 (input) or JP10 (output) causes all inputs and outputs to be scaled. Move the
CTI 2501 Quick Start Guide
5
jumper to the ENABLED position to select this function. The normal shipping configuration is
DISABLED for both inputs and outputs.
Selecting Digital Filtering
Locate the Digital Filtering Jumper “DIG FIL/CAL MODE” JP2 (see Figure 2.3). To enable digital
filtering, set the jumper in the “EN” position; to disable, set to the “DIS” position. Since many
analog input signals contain noise, CTI recommends using digital filtering unless maximum response
time is required. As shipped, digital filtering is ENABLED for all 8 analog inputs.
Selecting Voltage or Current Input Mode
Locate the 8 Voltage/Current Jumpers corresponding to input channels 1 through 8 (see Figure 2.3
for the location of these jumpers). For each input channel, select current mode by placing the jumper
in the “20MA” position or voltage mode by placing the jumper in the “VOLTAGE” position. For
each input channel set to current mode, you must set the corresponding Voltage Range Jumper to the
5V.
Selecting Voltage Input Range
Locate the Voltage Range Jumpers corresponding to input channels 1 through 8 (see Figure 2.3). For
each input channel operating in current mode, set the corresponding Voltage Range Jumper to 5V.
CAUTION:
For each input channel configured for current mode, the corresponding Voltage Range Jumper
must be set to 5V.
For each input channel operating in voltage mode, set the corresponding Voltage Range Jumper to
“5V” for 0 to +5V or –5 to +5V input range or “10V” for 0 to +10V or –10 to +10V input range.
Selecting Unipolar or Bipolar Input Mode
Locate the Unipolar/Bipolar Jumpers for each channel (see Figure 2.3). Set each jumper to “UNI” for
unipolar operation or “BI” for bipolar operation for each input channel with input ranges of 0 to
+5VDC, 0 to +10VDC, -5 to +5VDC or -10 to +10VDC. Select 5VDC range for all current
applications.
NOTE:
The 5V input signal range configuration is used for both 0 to 5VDC and 1 to 5VDC or
0 to 20mA and 4 to 20mA input signal ranges.
Selecting Output Voltage Range
The 2501 is capable of supporting Unipolar or Bipolar applications with an output range of 0 to
+5VDC, 0 to +10VDC, -5 to +5VDC or -10 to +10VDC. For each channel a hardware jumper selects
the range for that output circuit (see Figure 2.3). Select 5VDC range for all current applications.
6
CTI 2501 Quick Start Guide
Selecting Unipolar or Bipolar Output
Each output channel on the 2501 supports Unipolar or Bipolar output operation. Hardware jumpers
select operation of the output (see Figure 2.3). Select Bipolar for applications that drive the outputs
from -5 to +5VDC, -10 to +10VDC, or -20 to +20mA.
Setting DIP Switches to Match the Hardware Selections
Once the hardware jumpers are selected this information needs to be reported to the microcomputer.
The information is reported via DIP switches SW1, SW2, and SW3. Each input and output channel
uses 2 switches with a BCD code to indicate the state of the hardware jumpers.

Jumper Settings for Future Reference
See Appendix B. Jumper Settings Log Sheet to record any changes to the module’s jumper settings.
Inserting the Module into the I/O Base
When the module is fully seated in the slot, captive screws at the top and bottom will hold the
module in place. To remove the module from the I/O base, loosen these captive screws, and then
remove the module from the I/O base. Do not damage the edge connector at the back of the module
when inserting or removing the module.
CTI 2501 Quick Start Guide
7
WARNING: Always remove power from the I/O base before inserting a module to
minimize the risk of injury of damage to equipment. Never insert a module into a powered
I/O base.
Wiring the Output Connector
Output signals are provided through a connector assembly located on the front of the module. The
connector assembly consists of a header attached to the printed circuit card and a mating removable
screw terminal connector (see Figure 2.9). Wiring is connected through the removable screw
terminal connector.
Figure 2.9 Output Screw Terminal Connector Wiring
Connecting Voltage Output Wiring
First, loosen the wire locking screws on the output screw terminal plug. For voltage output circuits,
connect the signal wire to the VOUT screw terminal, and the return wire to the Return (channel
ground) screw terminal. Insert the wires in the appropriate holes next to the screws. When the wires
are inserted, tighten the screws. Repeat this procedure for the remaining voltage output channels.
Connecting Current Output Wiring
For current output circuits, connect the signal wire to the IOUT screw terminal, and the return wire to
the Return (channel ground) screw terminal. Insert the wires in the appropriate holes next to the
8
CTI 2501 Quick Start Guide
screws. When the wires are inserted, tighten the screws. Repeat this procedure for the remaining
current output channels.
Connecting the Shield Wiring
See Figure 2.10 below for a description of cable grounding and chassis ground.
Figure 2.10 Connecting the Shield Wiring
NOTE:
Five static drains are recommended on the 2501 to prevent static charges from building up. The
eight analog inputs, which share the same isolated common, may be protected by a single 10K to
Meg resistor from ANY analog negative (-) terminal to chassis ground. If ANY of the circuits being
monitored provide a static drain, then the resistor is not only not required, but not recommended - a
ground loop would result. Each of the four analog outputs require a separate static drain if the
circuits being driven does not provide a static discharge path. A 10K to 1 Meg resistor to chassis
ground should be sufficient. (Note also that chassis ground is available on front panel connector
pins B4, C2, DR, and D3.)
Connecting the Shield Wiring
First, loosen the wire locking screws on the output screw terminal plug. For voltage output circuits,
connect the signal wire to the VOUT screw terminal, and the return wire to the Return (channel
ground) screw terminal. Insert the wires in the appropriate holes next to the screws. When the wires
are inserted, tighten the screws. Repeat this procedure for the remaining voltage output channels.
CTI 2501 Quick Start Guide
9
Inserting the Screw Terminal Connector
When all the output signal wires are connected to the screw terminal connector, carefully insert the
connector into its header. Both the plug and header are keyed to prevent reverse wiring. When the
screw terminal is fully inserted onto the header, use the captive screws to secure the connector to the
front panel.
Connecting the 24VDC User Power Supply
The power supply is connected to the “D2” and “D6” positions for the connector on the front of the
module (as shown in Figure 2.9). Be sure to check that the fuse is present and intact. The fuse will
blow if the +24VDC power falls below ~21VDC or goes above ~31VDC, and will report a power
supply error code (+32753) to the PLC (see Figure 2.5 CTI/ Siemens® Error Code Definitions). See
the Troubleshooting section for replacement fuse recommendations.
Checking Module Operation
First, turn on the base supply power. If diagnostics detects no problems, the front panel status
indicator will light. If the indicator does not light (or goes out during operation) the module has
detected a failure. For information on viewing failed module status, refer to your TISOFT
Programming Manual. To diagnose and correct a module failure, refer to the next section on
troubleshooting.
NOTE:
If 24VDC power fails or is removed and then later restored, the module will automatically
resume normal operation. No external reset is required after power is restored.
You must also check that the module is configured in the memory of the PLC. This is important
because the module will appear to be functioning regardless of whether it is communicating with the
PLC. To view the PLC memory configuration chart listing all slots on the base and the inputs or
outputs associated with each slot, refer to your TISOFT Programming Manual. Example charts are
shown in the following figures, one for each login mode. Also, note the Wxs and Wys mix in Figure

If the line is blank or erroneous, re-check the module to ensure that it is firmly seated in the slots.
Generate the PLC memory configuration chart again. If the line is still incorrect, contact your local
distributor or CTI at 1-800-537-8398 for further assistance.
NOTE:
In the event a CTI analog module detects no user 24VDC or an onboard module failure, the
module will assert the module fail line and report the module failure in the I/O Status Word,
which is reported to the PLC CPU. CTI strongly recommends the user application monitor the
I/O Module Status Words which are Status Words 11-26 and apply to Controllers TI/545,
TI/555, TI/560 & 565, and the TI/575. The I/O Module Status Word can be used to report a
module failure for an I/O Module in any of the SIMATIC® 505 I/O slots. Please refer to
Siemens® 505 Programming Reference Manual for more information. If a module failure is
reported by the status word, the module should be replaced with a working unit and the failed
module sent in for repair.

TROUBLESHOOTING
Figure 3.1 Troubleshooting Matrix
When it is inconvenient to visually check the status indicator, use the TISOFT "Display Failed I/O"
or "Show PLC Diagnostics" support functions. Note that if the module power supply (user supply)
fails, the module will still be logged into the PLC even though it is not operating. In this case,
"Display Failed I/O" will not provide the information to accurately diagnose the problem.
CAUTION:
The module fuse F2 is user serviceable. If this fuse continuously blows, the module has a
serious component failure and should be returned to CTI for repair, or the module is being
supplied voltage in excess of ~31VDC.
In the event the user serviceable fuse F2 blows, its replacement should be a 0.5 A, 250V Time Lag
5x20mm fuse (Schurter 0034.3114 or equivalent).
If after consulting the chart above, you are unable to diagnose or solve the problem, contact your
local distributor or CTI at 1-800-537-8398 for further assistance.

CTI 2501 Quick Start Guide
APPENDIX A. COMPATIBILITY WITH SIEMENS® 505-7012/7016
Overview
The CTI 2501 8 Analog Input / 4 Analog Output Module was designed to be a drop-in replacement
for the Siemens® models 505-7012 and 505-7016. From set up of the module to wiring and PLC
reporting, the user will find many similarities between the CTI and Siemens® modules.
Using the CTI 2501 in a 505-7012 and/or 505-7016 application
The CTI 2501 should fulfill all the following requirements for the 505-7012 and 505-7016
replacement(s), as outlined below:
Module setup
Since the CTI 2501 allows for both Unipolar and Bipolar setup, the module does have a slightly
different module setup. See heading “Configuring the Module for Operation” to determine the details
in module setup.
Wiring
The wiring of the output connector is the same between the modules. See heading “Wiring the
Output Connector” for a detailed explanation of how this is accomplished.
If the module is used to supply voltage, the requirements of the input voltage to the module (2030VDC) remains the same in order to supply the resistive load of the field device (>1000Ω).
However, the maximum load resistance for current output drops to 600Ω at 20VDC and then climbs
linearly to 1000Ω at 24-30VDC.
Also noteworthy is the isolation achieved module to module with the same power supply by using
the CTI 2501 versus the Siemens® modules. With the 2501, each module is dielectrically isolated
from a common 24V power supply.
PLC Reporting
The word format is the same between the modules. See full length I.O.G. for a more detailed
explanation on PLC reporting.
Power Cycling
When the user power is supplied and the base power is transitioning on, the 2501 has the option to
either transition to hold the last output value until the next PLC update, as the Siemens® modules
do, or to go to zero until the next PLC update. See heading “Selecting Either Zero or Last Value
Output at Power Up” for further details.
