Product Introduction
The Allen-Bradley 1771-OAD AC Output Module is a digital AC output module designed for the PLC-5 1771 I/O platform by Allen-Bradley. It is used to switch AC loads in industrial automation systems under the control of a PLC, providing reliable and precise AC output control for a variety of field devices.
This module offers 16 AC output points, supporting operating voltages from 10 to 138 VAC and a recommended voltage range of 12–120 VAC. It can handle a maximum continuous current of 2 A per output and 8 A for the entire module. With a typical DC signal delay of 50 ms, the 1771-OAD ensures timely switching of AC loads in process control and automation systems.
Installed in a 1771 I/O chassis, the module communicates with the PLC-5 processor via the backplane. Its compact design, high output capacity, and reliability make it ideal for controlling motors, solenoids, lights, heaters, and other AC-powered devices in industrial environments.
