Description
Installation
1762 I/O is suitable for use in an industrial environment when installed in
accordance with these instructions. Specifically, this equipment is intended for use
in clean, dry environments (Pollution degree 2
(1)
) and to circuits not exceeding
Over Voltage Category II
(2)
(IEC 60664-1).
(3)
Item Description Item Description
1a upper panel mounting tab 5 bus connector cover
1b lower panel mounting tab 6 flat ribbon cable with bus connector (female)
2 power diagnostic LED 7 terminal block
3 module door with terminal identification label 8 DIN rail latch
4 bus connector
with male pins
9 pull loop
(1) Pollution Degree 2 is an environment where, normally, only non-conductive pollution occurs except that occasionally a
temporary conductivity caused by condensation shall be expected.
(2) Over Voltage Category II is the load level section of the electrical distribution system. At this level transient voltages are
controlled and do not exceed the impulse voltage capability of the product’s insulation.
(3) Pollution Degree 2 and Over Voltage Category II are International Electrotechnical Commission (IEC) designations.

Prevent Electrostatic Discharge
Remove Power
ATTENTION
!
Electrostatic discharge can damage integrated circuits or
semiconductors if you touch bus connector pins. Follow these
guidelines when you handle the module:
•
Touch a grounded object to discharge static potential.
•
Wear an approved wrist-strap grounding device.
•
Do not touch the bus connector or connector pins.
•
Do not touch circuit components inside the module.
•
If available, use a static-safe work station.
•
When not in use, keep the module in its static-shield box.
ATTENTION
!
Remove power before removing or installing this module. When
you remove or install a module with power applied, an electrical
arc may occur. An electrical arc can cause personal injury or
property damage by:
•
sending an erroneous signal to your system’s field devices,
causing unintended machine motion
•
causing an explosion in a hazardous environment
•
causing permanent damage to the module’s circuitry
Electrical arcing causes excessive wear to contacts on both the
module and its mating connector. Worn contacts may create
electrical resistance.
MicroLogix™ 1200 Isolated Relay Output Module 5
Publication 1762-IN017B-EN-P - March 2004
Mounting
Minimum Spacing
Maintain spacing from
enclosure walls, wireways,
adjacent equipment, etc.
Allow 50.8 mm (2 in.) of
space on all sides for
adequate ventilation, as
shown:
.
DIN Rail Mounting
The module can be mounted using the following DIN rails: 35 x 7.5 mm
(EN 50 022 - 35 x 7.5) or 35 x 15 mm (EN 50 022 - 35 x 15).
Before mounting the module on a DIN rail, close the DIN rail latch. Press the DIN
rail mounting area of the module against the DIN rail. The latch will momentarily
open and lock into place.
ATTENTION
!
Do not remove protective debris strip until after the module and
all other equipment near the module is mounted and wiring is
complete. Once wiring is complete and the module is free of
debris, carefully remove protective debris strip. Failure to remove
strip before operating can cause overheating.
TIP
1762 expansion I/O may be mounted horizontally only.
ATTENTION
!
During panel or DIN rail mounting of all devices, be sure that all
debris (metal chips, wire strands, etc.) is kept from falling into the
module. Debris that falls into the module could cause damage
when power is applied to the module.

Use DIN rail end anchors (Allen-Bradley part number 1492-EA35 or 1492-EAH35)
for environments with vibration or shock concerns.
Panel Mounting
Use the dimensional template shown below to mount the module. The preferred
mounting method is to use two M4 or #8 panhead screws per module. M3.5 or #6
panhead screws may also be used, but a washer may be needed to ensure a good
ground contact. Mounting screws are required on every module.
TIP
For environments with extreme vibration and shock concerns,
use the panel mounting method described below, instead of DIN
rail mounting.

System Assembly
The expansion I/O module is attached to the controller or another I/O module by
means of a ribbon cable after mounting as shown below.
Field Wiring Connections
Grounding the Module
This product is intended to be mounted to a well-grounded mounting surface such
as a metal panel. Additional grounding connections from the module’s mounting
tabs or DIN rail (if used) are not required unless the mounting surface cannot be
grounded. Refer to Industrial Automation Wiring and Grounding Guidelines,
Allen-Bradley publication 1770-4.1, for additional information.
TIP
Use the pull loop on the connector to disconnect modules. Do
not pull on the ribbon cable.
!
WARNING
EXPLOSION HAZARD
•
In Class I, Division 2 applications, the bus connector must
be fully seated and the bus connector cover must be
snapped in place.
•
In Class I, Division 2 applications, all modules must be
mounted in direct contact with each other as shown on
page 5. If DIN rail mounting is used, an end stop must be
installed ahead of the controller and after the last 1762
I/O module.

Wiring the Finger-Safe Terminal Block
When wiring the terminal block, keep the finger-safe cover in place.
1. Route the wire under the terminal pressure plate. You can use the stripped
end of the wire or a spade lug. The terminals will accept a 6.35 mm
(0.25 in.) spade lug.
2. Tighten the terminal screw making sure the pressure plate secures the wire.
Recommended torque when tightening terminal screws is 0.904 Nm (8
in-lbs).
3. After wiring is complete, remove the debris shield.
ATTENTION
!
Be careful when stripping wires. Wire fragments that fall into a
module could cause damage when power is applied. Once
wiring is complete, ensure the module is free of all metal
fragments.
TIP
If you need to remove the finger-safe cover, insert a screw driver
into one of the square wiring holes and gently pry the cover off.
If you wire the terminal block with the finger-safe cover
removed, you will not be able to put it back on the terminal
block because the wires will be in the way.

1 = relay energized (normally-open contact ON)
•
0 = relay not energized (normally-closed contact ON)
For each module, the output data file contains the controller-directed state of the
discrete output points. Bit positions 0 through 5 correspond to output points 0
through 5.
