Allen-Bradley 1746-OW16 SLC 16-Point Output Module

The Allen-Bradley 1746-OW16 is a 16-point relay-based digital output module for SLC 500 controllers, delivering 16 individually isolated normally open relay contacts for discrete load switching. It operates with 5-265 VAC or 5-125 VDC on its outputs, with a continuous current rating of 2.0 A per output (8.0 A per module total) and contact ratings of 2 A at 30 VDC, 2 A at 120 VAC, and 0.25 A at 250 VDC. Backplane current draw is 0.28 A at 5 VDC, and there is relay isolation between the outputs and the logic circuitry. The module is compatible with 1746 SLC 500 chassis and operates from 0°C to 60°C, designed for mounting in industrial control panels and automation systems. Common applications include controlling motor starters, solenoid valves, contactors, alarms, indicator lights, pumps, and other field devices in manufacturing equipment, conveyor controls, packaging machinery, material handling systems, and industrial process automation where relay outputs are required; this makes it a frequent choice for system expansion, retrofit projects, and maintenance by maintenance teams and system integrators. Common replacements include 1746-OW8, 1746-OB16, and 1746-OV32.
