Allen-Bradley 1756-OA16 ControlLogix 16-Point AC Output Module
The Allen-Bradley 1756-OA16 is a 16-point AC digital output module designed for the ControlLogix platform. It provides reliable switching for alternating current loads operating within a voltage range of 74 to 265 VAC. Engineered for industrial control architectures, this module delivers high-density output capabilities to interface controllers directly with industrial AC actuators, solenoids, and motor starters.
Output Performance and Electrical Characteristics
The module features 16 individual AC output points capable of handling a continuous current rating of 0.5 A per point. It operates efficiently within a 74 to 265 VAC voltage spectrum, accommodating standard industrial single-phase AC control supplies. The plug-in modular design allows rapid integration and replacement within a standard ControlLogix chassis without requiring complex wiring teardowns.
Installation and Physical Configuration
Housed in a standard rack-mount format, the unit weighs approximately 0.55 lbs and mounts directly into any available slot of a 1756 ControlLogix chassis. Removable terminal blocks (RTBs) are used to interface field wiring, allowing maintenance personnel to disconnect field cables easily without disturbing the module electronics. Proper fusing should be incorporated externally to protect individual output points against high-current surges and short circuits.
