Allen Bradley 1757-SRM System Redundancy Module – ProcessLogix/ControlLogix, Backplane Redundancy, 0–60°C Operation

The Allen Bradley 1757-SRM is a high-performance System Redundancy Module designed for ProcessLogix and ControlLogix platforms. It provides controller-level redundancy, enabling two ControlLogix or ProcessLogix controllers to operate in a synchronized, fault-tolerant configuration.

Engineered for demanding industrial environments, the 1757-SRM supports automatic switchover between primary and secondary controllers, ensuring continuous process uptime. It features low backplane power consumption, 0.75A at 3.3V, 1A at 5.1V, and 0.16A at 24V, with a power dissipation of 11.28W. Designed for rugged reliability, it operates in temperatures from 0°C to 60°C.
