Allen-Bradley 1757-SRM ControlLogix System Redundancy Module

The Allen-Bradley 1757-SRM ProcessLogix and ControlLogix System Redundancy Module is a solid-state device that is employed in critical industrial applications that should not be stopped under any circumstances in order to provide a redundancy system by using an identical pair of PLCs to guarantee operation at all times. The 1757-SRM redundancy module is designed for installation in any free slot of a ControlLogix chassis but predefining the order of the cards to install in each ControlLogix slot is recommended. Both PLC systems, called the primary and secondary PLC systems, should be identical for the redundancy system to work appropriately.
