Preinstallation
Considerations
This module must be used in a 1771-A1B through -A4B or later I/O chassis.This module does not contain surge limiting circuitry. Use this module for switching resistive loads only. It is not recommended for inductive or capacitive loads.
The outputs are arranged in 4 groups of 8, each group with its own common. The module can simultaneously switch all 32 outputs to separate loads, with a maximum of 12A per module. Each output can conduct a maximum load of 1.0A continuously at 30W maximum. Ac loads switched by the modules should have a power factor (PF) of 1.0.
Maximum interconnect cable length for this module is 1000 ft.
(304.8 meters).

Low Voltage Directive
This apparatus is also designed to meet Council Directive 73/23/EEC
Low Voltage, by applying the safety requirements of EN 61131–2
Programmable Controllers, Part 2 – Equipment Requirements and
Tests.
For specific information that the above norm requires, see the appropriate sections in this manual, as well as the following
Allen-Bradley publications:
•
Industrial Automation Wiring and Grounding Guidelines, publication 1770-4.1
•
Guidelines for Handling Lithium Batteries, publication AG-5.4
•
Automation Systems Catalog, publication B111
Power Supply
Requirements
The controller or I/O chassis power supply, connected through the backplane of the I/O chassis, powers the logic circuitry of the contact output modules. This supply also provides the necessary power to energize the coils of the module relays. The maximum current drawn from this supply when all coils are energized is 2.5A. Nominal backplane current is 1.8A.
Initial Handling Procedure
When handling the module, observe the following warning:
!
ATTENTION: Remove power from the 1771 I/O chassis backplane and field wiring arm before removing or installing an I/O module.
•
Failure to remove power from the backplane or wiring arm could cause module damage, degradation of performance, or injury.
•
Failure to remove power from the backplane could cause injury or equipment damage due to possible unexpected operation.
The contact output module contains components which can be damaged by electrostatic discharge. The module is shipped in an electrostatic shielded bag for protection. Follow the handling procedures outlined below to guard against damage to your module.
•
Touch a grounded object to discharge yourself before handling the module.
•
Do not touch the backplane connector or connector pins.
•
If you configure or replace internal components, do not touch other circuit components inside the module. If available, use a static-safe work station.
•
When not in use, keep the module in its static-free shield bag.

Installing Your Module
Selectable Contact Output Module Cat. No. 1771-OWN 3
In this section we tell you how to key your I/O chassis, set the relay output jumpers, install your module and make your wiring connections.
Keying the I/O Chassis
Use the plastic keying bands, shipped with each I/O chassis, to key your I/O slots to accept only this type of module. Place the keying bands on the chassis backplane between:
•
6 and 8
•
16 and 18
Slots on the rear edge of the circuit board are matched to these slots to allow insertion of this type of module. You can key any connector in an I/O chassis to receive this module except for the leftmost connector reserved for adapter or processor modules.
Setting the Relay Output Jumpers
When the output image table bit at the address corresponding to any output is energized (set to 1), the corresponding relay contact is closed or opened, respective to the jumper setting.
All outputs are individually selectable for either normally-open or normally-closed operation. They are pre-set for normally-open operation at the factory. To reset any jumper, proceed as follows:
1. Remove the 4 screws from the side cover and separate the circuit board from the 2 covers.
2. Move the jumper to the desired position. Jumpers are identified by jumper number and use (N.O. or N.C.). Refer to Table 1.A for jumper and terminal identifications.
3. Reinstall the circuit board in the module and replace the cover.

Inserting the Module Into the Chassis
1. Turn off power to the I/O chassis.
2. Position the module so that the circuit board on the rear of the module lines up with the top and bottom card guides in the chassis.
3. Slide the module into the chassis.
4. Press firmly to seat the module in the chassis backplane connector.
5. Swing the module locking latch down into place over the front edge of the module.

Connecting Wiring to the Module
You make connections to the module through the field wiring arm cat. no. 1771-WN. The arm pivots on the I/O chassis to connect with terminals on the front of the module and acts as a terminal strip. The wiring arm allows the module to be removed from the chassis without disconnecting wiring.
1. Make certain all power is removed from the module before making wiring connections.
2. Swing the wiring arm up into position on the front of the module.
The locking tab on the module will secure it into place.
3. Make your connections to the field wiring arm as shown in the connection diagram. (Use the label on the front of the wiring arm to identify your wiring.)
!
ATTENTION: The field wiring arm terminal identification number is not the same as the number of the bit which controls that output.

ATTENTION: Do not attempt to increase load current or wattage capability beyond the rating by connecting two or more outputs in parallel. The slightest variation in output relay switching time may cause one set of contacts to switch the total load current.
You can use the 1771-OWN output module to drive an input of a
120V ac input module (1771-IA, -IA2, -IAD) to indicate status of turning on a motor starter as shown below, for example, but you must connect a 15K, 2W resistor between the output and L2
(common). Inputs configured with the output module are not isolated from each other.
