Features:

  • 8-Point Discrete Configuration
  • High-Voltage AC Output
  • Modular FLEX I/O Architecture
  • Zero-Cross Switching Technology
  • Flexible Terminal Base Support
The Allen-Bradley 1794-OM8 is a robust 120V AC digital output module designed as a part of the versatile FLEX™ I/O distributed system. This module serves as a reliable interface for a PLC or PAC to execute control commands for high-voltage alternating current field devices. By providing 8 discrete points in a modular form factor, the 1794-OM8 bridges the gap between low-voltage control logic and high-power industrial hardware like actuators, valves, and alarm systems.

The Allen Bradley 1794-IE12 module is a reliable input component from the Flex I/O 1794 series. It operates within a nominal power supply voltage range of 10.5 to 31.2 volts DC, with a typical rating of 24 volts DC and a FLEXBus current requirement of 80 mA.

The 1794-OM8 Allen-Bradley Output Module may still be available for purchase and support from Amikon Limited beyond End-Of-Life (EOL) by the manufacturer (OEM).

A key technical advantage of the 1794-OM8 is its integration into the FLEX™ I/O platform, which prioritizes space efficiency and ease of maintenance. The module is designed to mount onto a terminal base that remains permanently wired, allowing the electronic module itself to be swapped out quickly in the event of a failure without disturbing the field wiring. This "Hot-Swap" capability is critical for reducing downtime in continuous process industries such as food and beverage, pharmaceuticals, and manufacturing.

Mount the Terminal Base: Position the terminal base on a 35 x 7.5mm DIN rail and rotate it to lock onto the rail.
Configure Keyswitch: Set the keyswitch (1) on the terminal base to position 8 to match the 1794-OM8 module.
Attach Module: Align the 1794-OM8 module with the terminal base, ensuring the pins are straight, and press down until you hear a click, indicating the latching mechanism is secure.
