Product Description

Description

The Allen-Bradley 1771-OZL is an 8-channel digital relay contact output module designed to provide reliable switching control within the PLC-5 system architecture. It offers dry contacts that eliminate leakage current, preventing accidental energization of highly sensitive load devices. The 1771-OZL module functions as an effective interface between control logic and field devices, providing electrical isolation and robust signal switching for industrial automation processes.

Features

  • Zero Leakage Current: Dry contact outputs eliminate solid-state leakage currents, ensuring high-sensitivity load devices remain de-energized when contacts are open.
  • Individually Isolated Channels: Features 8 channels with independent contact isolation, allowing for diverse voltage reference routing.
  • Robust Diagnostic Indicators: Active LED indicators on the front panel provide real-time status display of each relay channel for simplified maintenance.
  • Secure Connection System: Compatible with standard Allen-Bradley I/O chassis swing arms to simplify wiring and field replacement.

Applications

  • High-sensitivity relay and coil control
  • Interlocking and safety signal isolation circuits
  • Solenoid and contactor pilot duty switching
  • DCS and PLC interface systems in process industries

FAQ
What is the key benefit of dry contacts on this module?
The dry contacts on the module prevent any leakage current from flowing when the outputs are open, eliminating the risk of falsely energizing highly sensitive load devices.
Does the device require external power for its backplane logic?
No, the logic power is drawn directly from the 1771 I/O chassis backplane, requiring 1.0 A at 5V DC.
How many outputs does the module support?
The module supports 8 isolated relay contact outputs.
