Allen-Bradley 1756-OW16I Relay Isolated Output Module

The Allen-Bradley 1756-OW16I is a ControlLogix 16-point isolated-relay output module that provides sixteen individually isolated normally-open contacts for digital control in a single 1756 I/O backplane slot. Each output supports load voltages from 10 to 265 VAC or 5 to 150 VDC, with a continuous isolation rating of 250 V between outputs and the backplane and between individual outputs, and it draws about 150 mA from the backplane (5 V or 24 V). The module switches with a maximum delay of 10 ms and uses removable terminal blocks 1756-TBCH or 1756-TBS6H for field wiring, with a 36-pin backplane interface designed for ControlLogix systems requiring isolated relay outputs across 16 points.
