Product Description

Allen-Bradley output modules are critical components in Rockwell Automation’s Programmable Logic Controller (PLC) systems, including platforms like ControlLogix, CompactLogix, SLC 500, and POINT I/O. These modules act as interfaces between the PLC and field devices, converting digital signals from the controller into actionable outputs to drive devices such as actuators, relays, solenoids, motors, and indicator lights. Available in digital and analog variants, they cater to diverse industrial automation needs with high reliability and flexibility.
