Description

The Allen-Bradley 1746-OX8 is a high-performance relay output module designed for the SLC 500 programmable logic controller system. This module provides 8 isolated relay contact outputs, allowing for the control of various field devices such as motor starters, solenoids, and indicators. The 1746-OX8 is engineered to handle diverse voltage requirements, making it a versatile solution for industrial automation applications where electrical isolation between the controller and the load is required.

Features

  • 8 isolated N.O. (Normally Open) relay contact outputs.
  • Designed for seamless integration into the SLC 500 I/O chassis.
  • Provides electrical isolation between the PLC backplane and field devices.
  • Compatible with a wide range of AC and DC voltage applications.
  • Robust construction suitable for standard industrial environments.

Applications

This module is commonly utilized in industrial control systems for switching high-current or high-voltage loads that require galvanic isolation from the PLC processor. Typical applications include machine control, process automation, and interface logic for motor control centers.
