Allen-Bradley 1756-0A16IK Digital Output Module

Allen-Bradley 1756-OA16IK is a 16-point AC digital output module for the Rockwell Automation ControlLogix platform. It provides 16 independently isolated outputs that switch 74–265 VAC loads, with a rating of up to 1 A per point, enabling direct control of AC devices such as relays, contactors, and solenoids from a ControlLogix controller. The IK suffix denotes conformal coating on the circuitry, improving reliability in environments with moisture or chemical exposure. As a 1756 I/O backplane-compatible module, it integrates with existing ControlLogix systems to expand AC switching capacity across manufacturing lines, packaging equipment, conveyors, and process-control applications. Isolation between outputs helps minimize cross-talk and fault propagation, while the 16-point footprint supports scalable expansion within a single module to meet growing automation needs.
