Installation Instructions
This document provides information on:
important pre-installation considerations
power supply requirements
initial handling procedures
installing the module
using the indicators on the module for troubleshooting
module specifications
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).
If this product is installed within the European Union or EEA
regions and has the CE mark, the following regulations apply.

No. 1771-OWN 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. Use the plastic keying bands, shipped with each I/O chassis, to key your I/O slots to accept only this type of module.

- Page 5 Selectable Contact Output Module Cat. No. 1771-OWN 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.
- Page 6 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).
