1794-OW8

Product Overview

1794-OW8 is an Allen-Bradley FLEX I/O 8-point relay output module from Rockwell Automation designed for distributed industrial automation systems. This module provides 8 isolated normally open relay contact outputs for FLEX I/O platforms, allowing PLC systems to control a wide range of AC and DC field devices. Supporting relay switching up to 240V AC and 125V DC, with DIN rail mounting and FLEXBus communication, it is widely used in machine control, factory automation, process systems and industrial equipment applications.
