Allen-Bradley 1756-RM2

ControlLogix Enhanced Redundancy Module | Fiber-Optic Communication | 1 Gbps | High-Availability Control Systems

Product Detailed Description

The Allen-Bradley 1756-RM2 is an enhanced redundancy module for Rockwell Automation ControlLogix programmable automation systems. It supports redundant controller architectures designed to maintain control-system availability if the primary controller or associated components experience a fault. The module uses fiber-optic communication between redundancy partners and supports data transfer at up to 1 Gbps.The 1756-RM2 occupies one slot in a compatible ControlLogix chassis and connects to its partner module using the appropriate 1756-RMC series fiber-optic cable. A redundancy system typically requires two compatible redundancy modules, one in each redundant chassis. Compatibility depends on the controller family, chassis, firmware, and redundancy configuration, so confirm the system design before replacing or adding a module.
