The Allen-Bradley 1756-OA16I is a ControlLogix digital AC output module designed to control field-side industrial actuators, motor starters, and solenoids. Operating across a broad output voltage range of 74 to 265 V AC, the 1756-OA16I features 16 individually isolated channels to prevent cross-channel interference and ensure reliable system operation. Equipped with a 36-pin removable terminal block interface, this module integrates seamlessly into standard ControlLogix chassis architectures and supports minimum firmware revisions 1.0, 2.0, and 3.0 alongside Studio 5000 / RSLogix 5000 design software version V20 or higher.
