Allen-Bradley 1756-OW16I 16-Point Isolated Relay Output Module

The Allen-Bradley 1756-OW16I is a 16-point isolated relay output module for ControlLogix systems, designed to switch AC or DC field devices via individually isolated relay contacts. It provides 16 relay outputs rated 2 A per point (resistive) with a voltage range of 5–265 V AC or 5–125 V DC, mounts in a ControlLogix chassis, and operates from 0 to 60°C. Backplane current draw is 5 V DC or 24 V DC, depending on the module configuration, enabling flexible integration with common ControlLogix backplanes. Typical applications include motor starters, valves, alarms, heaters, and lighting circuits in manufacturing plants, packaging lines, material handling systems, and process control environments. Common replacements include 1756-OW16, 1756-OB16I, and 1756-OB32.
