Allen-Bradley 1756-OW16I Digital Output Module

The Allen-Bradley 1756-OW16I Digital Output Module is a 16-channel isolated relay output module for ControlLogix I/O, designed to switch discrete loads in industrial automation. Each relay output provides full isolation between the channel and the logic, enabling independent control of field devices such as actuators, lamps, solenoids, and valves across a ControlLogix backplane. Outputs support AC and DC loads with a typical rating up to 2 A per contact, and the module interfaces via the ControlLogix backplane with DIN rail or chassis mounting options depending on the system. Operating temperature range is 0°C to 55°C for standard industrial environments. This module is commonly used in conveyor systems, packaging machinery, material handling equipment, and process automation panels where multiple discrete loads must be switched in coordinated automation sequences. Common replacements include Allen-Bradley 1756-OW16, 1756-OW8, and Siemens 6ES7 322-1BH01-0AA0.
