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
60664-1).

) and to circuits not exceeding Over Voltage Category II
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.

Publication 1762-IN007B-EN-P- June 2013
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.

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.
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:
1762 expansion I/O may be mounted horizontally only.
Solid-State Output Module 5
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.

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.
Use DIN rail end anchors (Allen-Bradley part number 1492-EA35 or 1492-EAH35) for
vibration or shock environments.
For environments with greater vibration and shock concerns, use the panel
mounting method described below, instead of DIN rail mounting.
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 mechanical contact. Mounting screws are
required on every module.

TIP
ATTENTION
System Assembly
The expansion I/O module is attached to the controller or another I/O module by means of a
flat ribbon cable after mounting as shown below.
Use the pull loop on the connector to disconnect modules. Do not pull on
the ribbon cable.
Field Wiring Connections
Grounding the Module
This product is intended to be mounted to a well-grounded mounting surface such as a metal
panel. Refer to Industrial Automation Wiring and Grounding Guidelines, Allen-Bradley
publication 1770-4.1, for additional information.
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 6. If DIN rail
mounting is used, an end stop must be installed ahead of the controller
and after the last 1762 I/O module.

Output Wiring
Basic wiring of the 1762-OA8 is shown below.
A write-on label is provided with the module. Mark the identification of each terminal with
permanent ink, and slide the label back into the door
Publication 1762-IN007B-EN-P- June 2013
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
TIP
Finger-safe cover not shown for clarity.
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 0.90 Nm (8 lb-in.).
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.
Wire Size and Terminal Screw Torque
Each terminal accepts up to two wires with the following restrictions:
Wire Type Wire Size Terminal Screw Torque
Solid Cu-90 °C (194 °F) #14…22 AWG 0.904 Nm (8 lb-in.)
Stranded Cu-90 °C (194 °F) #16…22 AWG 0.904 Nm (8 lb-in.)

Tur n O n Ty pe - Triac outputs turn on at ac line zero cross, and off at zero current.
Recommended Loading Resistor - to limit the effects of leakage current through solid-state
outputs, a loading resistor can be connected in parallel with your load. For 120V AC operation,
use a 15k Ω, 2W resistor. For 240V AC operation, use a 15k Ω, 5W resistor.
Surge Suppression - Connecting surge suppressors across your inductive loads reduces the stress
on your triac outputs. This also helps minimize the load-induced electromagnetic emissions that
are conducted on your plant wiring. For 120V loads, we recommend the Littelfuse-Harris surge
suppressor, part number V175LA10A MOV or an equivalent device. For 240V loads, we
recommend the Littelfuse-Harris surge suppressor, part number V250LA20A MOV or an
equivalent device.
