Allen Bradley 1756-RM2 ControlLogix 5370 PLC Controller With 1 GHz Processor

The Allen‑Bradley 1756-RM2 is an enhanced redundancy module designed exclusively for  ControlLogix 5570 series PLC control systems. It enables bumpless redundant controller operation by synchronizing primary and backup ControlLogix chassis via high-speed fiber communication. Paired with two 1756-RM2 modules installed in separate control chassis, it achieves fast runtime synchronization and seamless controller switchover. This hardware guarantees continuous production for critical processes where unplanned downtime must be eliminated, widely cooperating with ControlLogix L7x series controllers to build high-availability industrial control architecture.
