Overview

The Allen-Bradley 1756-RM2 is a ControlLogix Redundancy Module designed to improve system reliability and uptime. By pairing two modules in separate ControlLogix chassis, you create a redundant system. The system automatically switches to the backup controller if the primary controller fails, ensuring continuous operation and minimizing downtime.

Key Features and Benefits

• Enhanced Redundancy: Synchronizes two controllers and switches automatically to the backup during a failure.

• High-Speed Communication: Supports up to 1000 Mbps for fast and efficient data transfer between controllers.

• Minimal Scan Time Delay: Provides a typical switchover delay of ~20 ms, reducing process disruption.

• Cross Loading: Transfers data seamlessly between controllers through redundant fiber ports.

• Enhanced Diagnostics: Advanced diagnostics help identify and resolve potential issues efficiently.
