ABB 1MRK000005-202 BFR01 1MRK000154-BFR01 Binary Input Output Module

Overview

ABB 1MRK000005-202 BFR01 is a binary I/O module for ABB RELION 670 series protection and control IEDs. ABB 1MRK000005-202 BFR01 1MRK000154-BFR01 acquires status signals from field switches, circuit breaker auxiliary contacts and isolators, and outputs binary control commands for trip, close and interlock operation. This ABB 1MRK000005-202 BFR01 1MRK000154-BFR01 is widely stocked as spare binary interface unit for substation relay and power protection automation assemblies.

Features

ABB BFR01 module supports galvanic isolation between field circuits and IED internal logic, suppressing interference from substation switching surge and ground potential difference. It is configured with multiple binary input channels for position feedback and alarm signal collection, and binary output relay contacts for executing breaker trip and close orders. BFR01 works as a plug-in rear module matched to RELION 670 series IED chassis. It has built-in diagnostic circuit to detect wire break, short circuit and power supply abnormality of input loops. Channel configuration and signal mapping can be set via PCM600 engineering software. This module follows IEC 61850, IEC 60255 and substation EMC standards. It is designed for 24/7 continuous operation in high voltage switchgear, distribution substation, generator protection panel and industrial power system relay cabinets. The codes 1MRK000005-202 and 1MRK000154-BFR01 represent the component code and configuration code of this unit.

Specifications

ABB BFR01 Binary I/O Module Brand: ABB Model: BFR01 Part No.: 1MRK000005-202, 1MRK000154-BFR01 Series: RELION 670 Type: binary input output plug-in module Matching device: RELION 670 IED protection relay Input: binary status input with galvanic isolation Output: dry contact relay output for control commands Rated control voltage: 24~250 VDC / VAC Isolation: reinforced isolation between field side and IED core Diagnostic: wire break detection, short circuit supervision Connection: rear screw terminal block Mounting: plug-in slot on IED chassis Protection class: IP20 inside relay cabinet Ambient temperature: -25℃ ~ +70℃ Status: genuine ABB substation relay spare

Principle

ABB 1MRK000005-202 BFR01 1MRK000154-BFR01 receives discrete status signals from primary equipment auxiliary contacts. This Binary Input Output Module converts field contact status into digital logic values and transmits to the IED main processor. When protection logic or remote control command is triggered, the module drives internal relay contacts to send trip or close signals to breaker control circuit. The isolation barrier prevents high voltage transient from damaging the IED core.

Applications

ABB 1MRK000005-202 BFR01 1MRK000154-BFR01 is deployed in transmission and distribution substation protection IED, generator protection system, motor feeder relay and switchgear control cubicles. It collects breaker position, isolator status and fault alarm, and outputs trip and close control signals. ABB 1MRK000005-202 BFR01 1MRK000154-BFR01 is stocked as spare binary I/O module for RELION 670 protection control assemblies.
