Allen-Bradley 1757-RM2 ControlLogix Redundancy Module

Product Description

Allen-Bradley 1757-RM2 ControlLogix Redundancy Module is a ControlLogix system redundancy communication module designed to provide high availability for industrial automation systems. It enables two ControlLogix controller chassis to operate in a redundant configuration, allowing automatic transfer from the primary controller to the secondary controller when a fault occurs, reducing system downtime and improving control system reliability.
