Original Equipment Manufacturer Component PRO RM 20

The PRO RM 20 is a redundancy module designed to connect two power supplies to compensate for a device failure and increase system availability. It is part of the Weidmüller PRO series, featuring a MOSFET-based design that enables optimal efficiency of over 98%. The module ensures that a stable 24 V DC control voltage is maintained even if one power supply unit fails. Each redundancy branch is capable of supplying the full output load .
