Allen Bradley 1756-RM2 Enhanced Redundancy Module

The AB 1756-RM2 is an enhanced redundancy module for the ControlLogix system, enabling high availability through chassis-based controller redundancy. It allows two ControlLogix controllers to operate in a primary/secondary configuration, automatically synchronizing tasks, data, and system status for seamless hot standby operation.

Designed for critical process control and high-uptime applications, the 1756-RM2 provides fast switchover response, minimizing downtime during controller failure events. It fits directly into the ControlLogix chassis and requires a fiber-optic communication cable for synchronization between primary and secondary controllers.
