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 IBMr XT, AT,PS/2r or compatible Personal Computer.

Output Characteristics
Fault Mode Selection
The 24/48 Volt DC 0.5 Amp Output Module is compatible with a wide variety of load devices, such as:
The module can be configured from the programmer
so that output points assume one of two states in response to certain operating or default conditions.
D Solenoids
D Motor starters
D Indicators
D Maintain existing output state
D Turn outputs OFF
The rating of 0.5 amp per point applies to the longterm current capacity of each point. Because of overall heat dissipation within the module, the maximum
current for each group of 8 outputs is limited to 2 amperes.
Each output on this module is capable of transiently
conducting a surge current which is much greater
than its long-term current rating. The rate at which
such surges can be repeated depends on the current
rating of the device and the duty cycle (percent of
time the device is ON).
For typical incandescent devices operating at a 50%
duty cycle, the following repetition rates apply.

If protection is required, a fuse as specified below may
be externally connected to each output point by the
user.

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: Only the power supply can be placed in the
leftmost rack position.

The module is wired as shown in Figure 2. Since each
group of eight outputs is isolated from the others, a
wire from the power source to the power input terminals for each group is required (power input terminals
for each group are not connected inside the module).
The detachable field wiring terminal board will accept
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 (2.10 mm2) 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.

connecting field wiring to the detachable terminal
board on this input module. Module features referenced in the following procedures which are common
to all IC697 I/O modules are illustrated in the following figure.

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 modulefrom 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.
