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.
