Allen-Bradley 1756-0A16I 16-Channel Output Module

The Allen-Bradley 1756-OA16I is a 16-channel discrete AC output module for ControlLogix that provides individually isolated outputs to switch AC loads from a single I/O module. It operates on 74…265 V AC (50/60 Hz) with per-channel ratings of 2 A at 30°C and 1 A at 60°C, for a module-wide maximum of 5 A at 30°C (4 A at 60°C). Outputs are isolated from the backplane and from each other, with 50 V continuous isolation, and wiring is via removable terminals 1756-TBCH or 1756-TBS6H. The module draws about 1.59 W from the backplane and can dissipate up to 5.5 W at 60°C, and it is part of Rockwell Automation’s Series 2 A I/O family designed for ControlLogix systems. Common applications include driving AC relays, contactors, valves, or lighting circuits in automation sequences, leveraging ControlLogix backplanes while keeping field wiring isolated from the controller.
