Description

The Allen-Bradley 1771-OZL is a high-performance digital output module designed for the PLC-5 programmable controller system. This module features 8 reed relay contact outputs, providing reliable switching for low-voltage control applications. It is engineered for integration into 1771 I/O chassis, offering a robust solution for industrial automation tasks requiring isolated contact switching.

Features

8 Form A (Normally Open) reed relay outputs.
Configured in 4 groups of 2 outputs each.
Supports a voltage range of 0–24 V AC RMS or 0–24 V DC.
Fast switching performance with 1 ms maximum operate/release and bounce times.
High isolation voltage: 1000 V between open contacts and 1500 V between coil and contact.
Compact design for standard 1771 I/O chassis mounting.

Installation Guidelines

Ensure the PLC-5 chassis power is disconnected before installing or removing the 1771-OZL module to prevent electrical damage.
Verify the module is fully seated in the 1771 I/O chassis slot and secured with the locking tabs.
Use appropriate shielded cabling for field wiring to minimize electromagnetic interference (EMI).
Ensure field wiring is routed away from high-voltage AC lines and high-current power cables.
Observe the 100 mA per output current limit to prevent relay contact degradation.
Maintain adequate ventilation within the enclosure to ensure the module operates within its specified temperature range.

FAQ
