1757-SRM system redundant module

Руководство по продукту：

1757-sRM is a system redundancy module of the Allen Bradley (Rockwell) ControlLogix/ProcessLogix platform, used to achieve controller level primary backup redundancy and ensure uninterrupted critical processes.
Core purpose: To achieve redundancy of ControlLogix dual chassis primary and backup controllers, seamless switching in case of failure.
Synchronization capability: The fiber link speed is 100Mbps, and the synchronization period is as low as 20ms.
Synchronization content: real-time synchronization program I/O、 Variables, timers/counters, and communication buffers.
Switching performance: The primary and backup switches can be completed within a single scanning cycle without disturbance or data loss.

Fiber interface: SC interface, compatible with 62.5/125 μ m multimode fiber, wavelength 1300nm.
Module specifications: occupying 2 slots, standard ControlLogix chassis installation.
Power consumption and heat dissipation: Maximum power consumption of 11.28W, heat dissipation of 38.49BTU/h.
Backboard current: 0.160A at 24VDC, stable load.
Compatible with redundant CPUs such as 1756-L61R/L63R/L73R.
Supporting requirements: Redundant power supply (such as 1756-PA72R) and redundant I/O network are required.
Status indication: The panel LED displays OK, SYNC, FAULT and other statuses for easy maintenance.

Software configuration: Studio 5000 unified configuration, a set of programs automatically manage primary and backup logic.
Industrial environment: wide temperature design, adaptable to harsh environments, сильная антиинтерференционная способность.
Industry applications: high availability scenarios such as electricity, oil and gas, химический, water treatment, и т. д..
Certified Compliance: Compliant with industrial standards, reliable for long-term operation, and reduces downtime risks.
The redundant module of the 1757 SRM system, with high-speed synchronization, seamless switching, and high reliability as its core, is the core board for implementing controller redundancy on the ControlLogix platform.
