Allen-Bradley 1756-OW16I Digital Relay Module 1756OW16I

Description:

The Allen-Bradley 1756-OW16I Digital Relay Module is a discrete output module used in industrial control systems to provide 16 isolated relay output channels for machine control and logic functions. Designed for use with Allen-Bradley ControlLogix systems, this module interfaces with field devices such as actuators, lamps, solenoids, and valves to support complex automation sequences. Maintenance teams, OEM machine builders, and system integrators use this output module for system expansions, control panel upgrades, and replacement of existing modules to support increased output requirements in distributed control architectures.

Applications:

The 1756-OW16I digital relay module is commonly applied in industrial automation systems where multiple isolated relay outputs are needed. Typical installations include conveyor systems, packaging machinery, material handling equipment, process automation panels, and manufacturing cells requiring switching of discrete loads. Its isolated relay outputs provide flexible interfacing with AC and DC field devices in factory automation and control applications.
