Allen-Bradley 1756-OW16I 16 Pt Digital Module 1756OW16I

Description:

The Allen-Bradley 1756-OW16I is a 16-point isolated relay digital output module designed for ControlLogix automation systems to control AC or DC field devices. It provides individually isolated relay contacts, allowing flexible switching of motors, solenoids, contactors, and signaling devices within high-performance Logix-based architectures. Commonly installed in motor control centers, production lines, packaging equipment, and process control systems, this module expands discrete output capability in ControlLogix chassis assemblies. Maintenance teams and system integrators use this module for system expansion, replacement of failed output cards, retrofit projects, and maintaining reliable discrete control in industrial environments.

Applications:

The 1756-OW16I digital output module is used to switch field devices requiring relay-based control, including motor starters, valves, alarms, heaters, and lighting circuits. It is widely applied in manufacturing plants, material handling systems, water and wastewater facilities, and heavy industrial processes where electrical isolation and dependable output switching are required.
