A-B 1756-RM
The A-B 1756-RM module, the redundant module in Rockwell Automation’s ControlLogix family, is A key component used to improve system reliability. It guarantees the continuous operation of the system by providing a redundant configuration that ensures that when one module in the system fails, another module can take over its functions.
Product name
Rockwell Automation ControlLogix redundant modules
Product description
The 1756-RM module is typically used with the ControlLogix 5570 series controllers. It can realize the redundant control of the controller and improve the reliability of the system. When one controller fails, the standby controller can automatically take over control to ensure the continuity of the production process.
