Product Overview

ABB 500BIO01 (1MRB150005R1/J) is a dedicated binary input‑output hardware module for the ABB REB500 busbar protection system. It forms the physical signal interface between the protection unit logic and high‑voltage primary plant equipment such as circuit breakers, disconnectors and auxiliary relays. Opto‑isolated inputs acquire auxiliary contact status feedback from switchgear; relay outputs execute trip and interlock commands for busbar fault conditions. Conformal coating improves reliability in substation cabinet environments. It is widely stocked as original spare hardware for maintenance and retrofit of legacy REB500 busbar‑protection installations in power substations.

Series

500BIO01 belongs to the REB500 busbar‑protection hardware family. The REB500 platform delivers high‑speed busbar differential protection for medium‑and‑high‑voltage switchgear yards. The system consists of central processing units, signal acquisition boards and BIO binary I/O modules. Different hardware revisions are marked by suffix letter variants such as /J for firmware and component revision control.

Function

500BIO01 1MRB150005R1/J reads auxiliary‑contact status from circuit breakers and disconnectors via opto‑isolated binary inputs, and transmits status information to the REB500 central protection unit over the internal backplane bus. When busbar‑fault protection logic triggers, the module activates relay outputs to send trip commands to high‑voltage switchgear. Built‑in diagnostics detect channel failures and report fault information to the protection system for alarm logging. It realizes safe galvanic separation between substation field‑circuit signals and the protection‑relay internal logic.

 

Purpose

Provide binary‑signal interface between REB500 busbar‑protection relay and high‑voltage substation switchgear. Replace defective BIO modules to restore status‑acquisition and trip‑output functions for busbar‑protection systems. Used for spare‑part stocking and maintenance of legacy REB500‑equipped power‑substation installations.

 

Application Fields

HV‑/MV power‑substation busbar‑protection systems, utility‑power grid substations, industrial‑plant main‑switch‑yard protection, power‑plant auxiliary‑switchgear protection, legacy ABB REB500 busbar‑protection‑system maintenance and retrofit projects.
