ABB 1MRB150005R1/K 500BIO01 Binary Input/Output Module

Product Description

The 1MRB150005R1/K (type 500BIO01) is a binary input and output module for ABB REB500 busbar protection relay system. It collects binary status signals from circuit breakers, isolators and auxiliary contacts, and outputs relay trip/control commands. It is the core I/O interface for busbar protection, transmitting field signals to the central unit and executing protection action commands, widely used in power substation busbar protection cabinets.
