Description

The Allen-Bradley 1771-OZ is a PLC-5 relay contact output module designed to provide dependable discrete control signaling within the 1771 I/O chassis architecture. This single-slot module serves as an electromechanical interface between the programmable controller and external actuators, indicators, and control devices requiring isolated switching capability. It features built-in status indicators for each individual output channel to simplify diagnostic troubleshooting during system operation.

Engineered for standard industrial control environments, the 1771-OZ integrates directly into any available single slot within a compatible 1771 I/O chassis. The module handles low-voltage switching tasks while ensuring electrical isolation between the logic backplane and field-connected devices. During system power transitions, output channels may momentarily change state as the chassis power supply executes its initialization sequence.

Features

  • Equipped with 8 Form A (Normally Open) relay contact output channels
  • Supports operating voltage ranges from 0 to 24 VAC rms and 0 to 24 VDC
  • Maximum continuous current rating of 100 mA per output
  • Fast 1 ms maximum operate, release, and contact bounce response times
  • Includes channel-level status indicators for immediate visual feedback of energized outputs
  • Occupies a single slot in any standard 1771 I/O chassis architecture

Applications

  • Interfacing low-voltage control logic with discrete actuators and indicators
  • Switching low-level DC and AC control signals within PLC-5 rack systems
  • Isolating sensitive controller electronics from external load transients
  • Expanding discrete output capacity in legacy 1771 I/O distributed racks
