Allen-Bradley 1757-SRM System Redundancy Module
The Allen-Bradley 1757-SRM System Redundancy Module is designed for mission-critical applications where downtime is unacceptable.
This module ensures seamless redundancy between primary and backup controllers, providing a highly reliable and available system.
With its robust design and wide operating temperature range, it can withstand harsh industrial environments.
The module supports Ethernet/IP communication for easy integration into existing networks.
Certified to CE, UL, CSA, and ATEX standards, the 1757-SRM is suitable for use in various industries including manufacturing, oil and gas, and water treatment.
Its hot standby redundancy method guarantees minimal downtime in case of a controller failure, making it an essential component for any high-reliability industrial control system.
ControlLogix Redundancy Module:
The 1757-SRM is a module used to provide redundancy in Allen-Bradley ControlLogix and ProcessLogix systems. This means that it helps create a backup system to keep critical processes running even if the primary controller fails.
Function:
Its primary function is to maintain communication and synchronization between the primary and secondary controllers. This ensures that the secondary controller has an up-to-date copy of the primary controller’s data.
It helps in “cross loading”, i.e. transferring any changes that occur in the primary controller to the secondary controller.
Key Features
High-speed data transfer between redundant chassis using fiber optic communication.
LED status indicators show the operational status of the module.
This is a dual-channel module.
Important Notes:
This model is considered an older generation redundancy module. Newer systems typically use the 1756-RM or 1756-RM2.
Two identical control logix chassis are required to use this module.
Application:
Used in industries where downtime is critical, such as
Oil and gas
Chemical processing
Pharmaceuticals
Any process that requires continuous operation.
