Allen-Bradley 1794-OW8 Relay Output Module 1794OW8

Description:

The Allen-Bradley 1794-OW8 Relay Output Module is a discrete output module used in industrial control systems to provide eight relay output channels for machine control and logic functions. Designed for use with Allen-Bradley FLEX I/O systems, this module supports multiple relay outputs to interface with field devices such as solenoids, lamps, and actuators in automation circuits. Maintenance teams, OEM machine builders, and system integrators use this output module for system expansions, retrofit projects, and replacement of existing modules to support increased output requirements in distributed control architectures.

Applications:

The 1794-OW8 relay output module is commonly applied in industrial automation systems where multiple relay outputs are needed to control field devices. Typical installations include packaging machinery, conveyor systems, material handling equipment, automated test stands, and factory process controls that require switching of sensors, actuators, solenoids, and indicator circuits. Its relay outputs allow versatile interfacing with both AC and DC loads in discrete control applications across manufacturing environments.
