The Allen-Bradley 1756-RM is a ControlLogix Redundancy Module specifically designed for enabling controller redundancy within the ControlLogix platform. It seamlessly manages two identical controllers, ensuring uninterrupted operations through its embedded LED indicators for system monitoring and health status. Compatible with various ControlLogix chassis and power supplies, the 1756-RM operates with speeds up to 100 Mbps when paired with a module of the same series and connects using a single-mode LC fiber optic interface. It requires the 1756-RMCx cable for synchronization and offers robust configurability through the Redundancy Configuration Tool and Studio 5000 Logix Designer. This single-slot module boasts a power dissipation of 9 Watts and thermal dissipation of 31 BTU per hour, and it operates efficiently within a temperature range of 0 to 60 degrees Celsius. Certified by CE, CSA, Ex, C-Tick, and c-UL-us, it adheres to stringent industrial standards, reflecting its reliability and durability in demanding environments.
