Allen-Bradley 1771-0AD is an eight-channel AC output module designed for PLC-5 and SLC 500 control systems, enabling direct switching of AC loads from the controller. It provides eight independent outputs that operate over a 12 to 120 V AC range, suitable for driving devices such as relays, contactors, lights, and other common AC loads. Each channel uses zero-cross switching to minimize electrical noise when switching AC power. This unit is preowned and ready to integrate into compatible Allen-Bradley backplanes and chassis.
