Allen-Bradley 1756-RM2 is a ControlLogix redundant module. It has enhanced features with speeds up to 1000 Mbps. When paired with the 1756-L7x controller in both cases, it provides the best scanning performance. For cross loads, the 1756-RM2 uses redundant fiber optic ports with no single point of failure. During channel switching, the processing chassis stays synchronized, while scan times can experience a delay of about 10 milliseconds. It has enhanced security features with interference-free diagnostics.

The 1756-RM2 redundant module consumes 1.16A current at 5.1V DC and 3.4 mA current at 24V DC. It has a maximum power consumption of 6W and a heat dissipation of 21 BTU/ hour. It can be installed in any slot in the ControlLogix chassis. 1756-RM2 weighs 0.64 LBS. It has an open shell. For communication, it supports up to 7 enhanced control networks and Ethernet /IP communication modules. For cabling, the 1756-RM2 supports 1756-RMC1, 1756-RMC3, and 1756-RMC10 cables in lengths of 1, 3, and 10 meters, respectively.
