Allen-Bradley 1771-OW16 Electromechanical Contact Output Module

The Allen-Bradley 1771-OW16 is a 16-relay electromechanical output module for PLC-5 and 1771 I/O control systems, providing isolated relay-based switching for industrial automation. It offers 16 normally open outputs, each rated at 2 A for a total of 8 A per module, with an operating voltage range of 5-265 VAC or 5-125 VDC and contact ratings of 2 A at 30 VDC, 2 A at 120 VAC, and 0.25 A at 250 VDC; it also provides relay isolation between outputs and logic circuitry and a backplane current draw of 280 mA at 5 VDC, with Alternate Part Number 1771-0W16. The module is compatible with 1771 I/O chassis and uses 1771-WH wiring arms, is chassis-mounted, and operates 0°C to 60°C, commonly used to control motor starters, solenoid valves, contactors, pilot lights, alarms, and pumps in packaging, conveyor, assembly, and process-control environments.
