The module is mechanically keyed to ensure correct
replacement with a similar type in the field. I/O references are user configurable without the use of jumpers or DIP switches on the module.
Configuration is done using the configuration function of the MS-DOSr or Windowsr programming
software running on Windowsr 95 or Windows NTr
over Ethernet TCP/IP or through the SNP port. The
Programming Software configuration function is
installed on the programming device. The programming device can be an IBM XT, AT, PS/2 or compatible Personal Computer.

Input Characteristics
This input module is designed to have both positive
and negative logic characteristics in that it sinks or
sources current from the input device to the user common. The input device is connected between the
power bus and the module input as shown above.
This module is compatible with a wide variety of input devices, such as:
D Pushbuttons, limit switches, selector switches;
D Electronic proximity switches, both 2-wire and
3-wire.
In addition, inputs on this module may be directly
driven by any IC697 PLC voltage compatible output
module.
The input circuitry provides sufficient current to ensure reliable operation of the switching device. Input
current is typically 10mA in the ON state, and can accept up to 2 mA leakage current in the OFF state
without turning on.
3-wire proximity switches are easily applied, since
they provide low voltage drop in the ON state and
low leakage current in the OFF State.
patible with many such 2-wire devices; however each
device type must be carefully evaluated for compatibility in both the ON and OFF states.
To determine compatibility with a specific proximity
switch, find the ON state characteristics of the switch
in the diagram shown below. If that point falls to the
left of the input load line, the ON state characteristics
are compatible. As an example, the ON state requirements of a compatible proximity switch of 3mA at 5
volts drop are shown below.
OFF state compatibility is assured if the proximity
switch leakage is less than 2mA with a module input
voltage of 5 volts or less.

2-wire proximity switches derive their power from the

Input Filter Selection
With the IC697 PLC and certain other CPU options,
this module may be configured to have either a 1mS
or 10mS input filter. Configuration is on a module,
not per point basis; all points have the same filter
time. See the applicable Programmable Controllers Reference Manual for detailed information.

When used with the IC697 CPU, input point A1 may
be configured to cause a CPU interrupt. Configuration allows the CPU to be interrupted on either the
rising or falling edge of the signal transition. Interrupt response is not affected by input filter time selection. Refer to the applicable Programmable Controllers
Reference Manual for detailed information.

Module Mechanical Keying
14
This module includes a mechanical key that prevents
inadvertent substitution of one module type for
another in a given slot. The key fits a uniquely
shaped area on the board below the connector. Each
module has a key packaged with it.
16
When the module is first installed, the key latches
onto the backplane center rail. When the module is
extracted, the key remains in the center rail, configuring the slot to accept only identical module types.
If it is necessary to change the module location in the
rack after the key has been latched onto the center rail
of the rack, the key can be removed by pushing it upward to unhook the latch while pulling it off the rail.
It may then be reinserted onto the module and the
module inserted into the rack in the desired location.
Note that in an IC697 PLC rack only the power supply
can be placed in the leftmost rack position, and slot 1
(adjacent to the power supply) must always contain a
CPU (in rack 0 - the CPU rack), or a Bus Receiver
Module (in an expansion rack).

Field Wiring
38
The module is wired as shown in Figure 3. Since each
group of eight inputs is isolated from the others, a
wire from the power source to the power input terminal (10, 20, 30, or 40) for each group is required (pow-

1. Turn off power before removing or installing terminal boards. Open the hinged door on the module to access a jackscrew which holds the terminal
board securely in place. The detachable field wiring terminal board can now be removed from the
module by turning the jackscrew counter-clockwise until it is fully disengaged.
2. To remove the terminal board, grasp the top of the
terminal board and swing it outward.
Caution
Do not use the hinged door to remove the
terminal board. The hinged door could
be damaged if this is done.

3. The terminal board is designed to accept wire sizes
from AWG #22 (0.36 mm2) through AWG #14
(2.10 mm2). It is important that when using AWG
#14 (2.10 mm2) wire for wiring all points, that a
maximum insulation diameter of .135 inch
(3.43mm) not be exceeded. To ensure proper connection, two wires may be terminated on any one
terminal only if both wires are the same size.
4. The terminal board is designed to accept a maximum of (40) AWG #14 (2.10 mm2)wires. If AWG
#14 (2.10 mm2) wires are to be used, then wire
markers should be placed at least 8 inches (203
mm) from termination end to provide sufficient
space for the hinged door to close.

5. After completing connections to all modules in a
rack, the wire bundle must be secured. To ensure
that the wire bundle is secured properly, it is recommended that a cable tie be wrapped around the wire
bundle and tightly secured through the cable tie
cleat located at the lower right corner of the terminal
board. For extremely large wire bundles, additional
cable ties should be used.
6. A door label insert is included with each module to
indicate circuit wiring information and provide space
to record user circuit wiring identification. A slot is
provided on the hinged door to allow for insertion
of this label. If the label is difficult to insert, crease
the scored edge before insertion. The outside label
has a color coded stripe to allow quick identification
of the module voltage type (blue: low voltage; red:
high voltage).
7. After field wiring is completed, the terminal board
should be securely fastened to the rack by inserting
the terminal board strap (attached to each module)
into the small rectangular slots in the bottom card
guide grill on the rack. This strap not only secures
t

the terminal board to the rack, it also provides a
way of identifying the wired terminal board with its
correct mating rack slot location.
8. For adequate module ventilation, it is recommended
that at least a 6 inch (152mm) clearance be allowed
above and below the rack grill. Wire bundles should
not obstruct the rack grill work.
Removing an I/O Module
The instructions below should be followed when removing an I/O module from its slot in a rack.
D Grasp the board firmly at the top and bottom of
the board cover with your thumbs on the front of
the cover and your fingers on the plastic clips on
the back of the cover.
D Squeeze the rack clips on the back of the cover
with your fingers to disengage the clip from the
rack rail and pull the board firmly to remove it
from the backplane connector.
D Slide the board along the card guide and remove it
from the rack.
