Input Characteristics
This input module is designed to have both positive
and negative logic characteristics - 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:
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.
D Pushbuttons, limit switches, selector switches;
D Electronic proximity switches, both 2-wire and
48V SUPPLY

3-wire.
12
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 4.7mA 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.
2-wire proximity switches derive their power from the
signal connections; thus both the ON state voltage
and the OFF state leakage current are higher than for
3-wire devices. This module is designed to be compatible with many such 2-wire devices; however each
device type must be carefully evaluated for compatibility in both the ON and OFF states.

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 Controller Reference Manual for detailed information.

Interrupt
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 Controller Reference Manual for detailed information.
The wire bundle can be secured to the terminal board
by passing a cable tie through a cleat located at the
lower corner of the terminal board.

The detachable field wiring terminal board will accept
wire sizes ranging from #22 (0.36 mm2 ) through #14
(2.10 mm2 ). Two wires may be terminated on a given
lug if both wires are the same size. There is room for
a bundle of forty #14 (2.10 mm2 ) wires to be routed
out through the terminal board cavity.

The module is wired as shown in the illustration on
the right of this page. Since each group of eight inputs is isolated from the others, a wire from the power source to the power input terminal for each group
(terminal number 10, 20, 30, or 40) is required (power
input terminals for each group are not connected inside the module).

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 only the power supply can be placed in the
leftmost rack position.

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.

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. The
key is included with each module.

1. Turn off power before removing or installing terminals 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 5.
Caution
Do not use the hinged door to remove the
terminal board. The hinged door could
be damaged if this is done.
45-4
3. The terminal board is designed to accept wire sizes
ranging 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
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
t
Series 90 -70 Programmable Controller Data Sheet Manual
GFK-0600F
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 (152 mm) 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.
