Allen Bradley 1794-OW8 Flex 8 Point Isolated Relay Output Module

Product Introduction

The Allen-Bradley 1794-OW8 Flex 8 Point Isolated Relay Output Module is a high-performance relay output module designed for the FLEX I/O series. Manufactured by Rockwell Automation under the Allen-Bradley label, this module provides eight isolated digital relay outputs for controlling a wide range of field devices.

The 1794-OW8 module supports 24 VDC power supply and features a response time of 10 ms, making it suitable for industrial applications that require precise and reliable switching. Each channel can handle up to 2 A, allowing control of motors, solenoids, lamps, and other actuators. Its isolated relay design ensures electrical separation between channels and the backplane, protecting both the controller and field devices from electrical faults.

This module is compact and rugged, suitable for use in harsh industrial environments. It integrates seamlessly with FLEX I/O controllers and other Allen-Bradley automation systems, providing scalable and flexible control solutions for manufacturing, process automation, and building management applications.
