The TTL Input Module for the IC697 programmable
controller provides 32 TTL compatible input points
which are configured as one group.
No user power is required and the use of open-collector drivers is simplified since each input has an internal pullup.

LED indicators which give the ON-OFF status of each
point on the logic (PLC) side of the circuit are included at the top of the module.
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
Interrupt
This input module is designed to have negative logic
characteristics - it sinks 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.
When used with an 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 Programmable Controller Installation Manual for detailed information.
This module is compatible with a wide variety of input devices, such as:
D
Pushbuttons, limit switches, selector switches;
D
Counters, BCD outputs, and other TTL compatible outputs.
In addition, inputs on this module may be directly
driven by any IC697 PLC voltage compatible output
module.
The module contains an isolated 5V supply and pullup resistors for each input point. This configuration
simplifies the use of open-collector drivers and eliminates the need for a user supplied power source.
Input current is typically 1.7mA in the ON state, and
can accept up to 1.1mA leakage current in the OFF
state without turning on.
Input Filter Selection
With the IC697 PLC and certain other CPU options,
this module may be configured to have either a 1 ms
or 10 ms input filter. Configuration is on a module,
not per point basis; all points have the same filter
time. See the applicable Programmable Controller Installation Manual and the Programming Software User’s
Manual for detailed information.
47-2
Module Mechanical Keying
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.
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
The module is wired as shown in Figure 2. Since the
32 points share a common, only one connection is required between user common and the module common (pin 20 or 40). However, two user connections
are provided for wiring convenience.

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 as shown in
Figure 3.
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 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.
