The Allen-Bradley 1756-RM2K is a redundancy module developed by Rockwell Automation for the ControlLogix system.
It enables controller redundancy in critical automation applications by allowing primary and secondary controllers to operate in a synchronized configuration.
The 1756-RM2K supports Ethernet-based ControlLogix systems and is typically the only redundancy module required in a chassis.
It has a current draw of 1.16 A at 5.1 VDC and 3.4 mA at 24 VDC, providing efficient operation while maintaining high reliability and fault tolerance.
The module is a key component in achieving high system availability and minimizing downtime in industrial automation networks.
