ABB RLM01 redundant connection module

Product Description

The ABB RLM01 (part number 3BDZ000398R1) is a redundant connection module designed for the ABB AC800M controller series, a core element of the ABB 800xA distributed control system. Its primary function is to maintain continuous operation by providing a secure communication link between two controllers.

In the event of a primary controller failure, the RLM01 enables a seamless switchover to a standby controller, ensuring system reliability and uptime. With support for both fiber optic and electrical redundancy links, it offers flexible integration in critical industrial automation environments.
