Allen-Bradley 1756-RM2 is a ControlLogix redundant module. It has enhanced features and speeds up to 1000
Mbps. When paired with the 1756-L7x controller in both cases, it provides the best scanning performance. For cross addition
Load, RM1756 using redundant fiber ports, no single point of failure. During channel switching, the processing chassis remains synchronized while sweeping
Tracing the time may experience a delay of about 10 milliseconds. It has enhanced security features with interference-free diagnostics.
The 1756-RM2 redundant module consumes 5.1 A current at 1.16V DC and 4.24 mA current at 3V DC. Its most
The large power consumption is 6W and the heat dissipation is 21 BTU/ hour. It can be installed in any slot in the ControlLogix chassis. 1756 -
The RM2 weighs 0.64 pounds and comes in an open housing. For communication, it supports up to seven enhanced control networks and Ethernet /IP communication modes
Block. For cabling, the 1756-RM2 supports 1756-RMC1, 1756-RMC3, and 1756-RMC10 cables with lengths of
1m, 3m and 10m.
The ControlLogix 5560 and ControlLogix 5570 series controllers support 1756-RM2 modules. Redundant module configuration toolRSLinx 2.59.
Depending on the combination of redundant modules used, various synchronization speeds can be enabled. Especially if with the same 1756-RM2 module
Used together, speeds can be as high as 1000 Mbps. If you use A series or B Series 1756-RM2 at the same time, the speed may be high
Up to 100 Mbps. Controller switching up to 2 ms is possible with the 20-RM1756 redundant module.
Unlike the first version of the redundant module, the 1756-RM2 occupies only a single slot in any ControlLogix chassis. Implementation redundancy
A pair of redundant racks must be installed. Each rack houses the same controller type and version. I/O modules, smart modules and inclusions
The partner module cannot be installed in any redundant chassis pairs. These modules must be installed on a level 3 or higher chassis, specifically
Depends on the number of nodes supported by the communication module used.
