Functions
The 120 volt AC Input module for the programmable
controller provides 32 input points in four isolated
groups of eight points each. This allows each group of
eight points to be used on a different phase of the AC
supply.
The input is reactive (resistor/capacitor input) with
current-voltage characteristics which meet IEC standard (type 2). The input characteristics are compatible
with a large range of available proximity switches.

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.

MODULE
This module is compatible with a wide range of both
2-wire and 3-wire proximity switches. To determine
compatibility with a specific proximity switch, find the
ON state characteristics of the switch in the illustration below.
Input Characteristics
The 120 Volt AC Input 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
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 5mA at 20 volts drop is shown.
3-wire
The input circuitry is capacitive to give low heat dissipation and associated high reliability and long life.
In addition, the OFF-state current must be less than
2.2mA.
Input current characteristics provide 10mA typically
in the ON state, and can sink up to 2.2mA of leakage
current in the OFF state to the input device.

120 Volt AC, 32-Point Input Module
Module Power
The 120 Volt AC Input Module requires 0.35 amps
from the 5-volt bus on the backplane.
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. The
key is included with each module.
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 only the power supply can be placed in the
leftmost rack position.

Field Wiring
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).
The detachable field wiring terminal board accepts
wire sizes 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 wires to be routed out through
the terminal board cavity.
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.

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 2.
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 mm) through AWG #14 (2.10
mm). 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.
