Description
PRODUCT OVERVIEW
ABB 1MRK000284-ABR02 is a plug-in binary input board specially matched with ABB Relion 650 & 670 series protection control devices. It is responsible for collecting position signals of circuit breakers, isolating switches, auxiliary relays and other field switching quantities in the substation primary system, converting external passive/active switching signals into standard digital signals identifiable by the IED main control board, and uploading status data for bay logic judgment, equipment state monitoring and fault event recording.
Every channel adopts optocoupler isolation design with built-in surge absorption and filtering circuits, which can effectively resist instantaneous overvoltage and strong electromagnetic interference in substation sites. Widely applied in routine maintenance, fault replacement and emergency spare backup of feeder protection, transformer protection, busbar protection and generator protection equipment in power transmission & distribution systems.

FAQ
What core function does 1MRK000284-ABR02 undertake in protection relays?
It is the switching state perception unit of the protection device, feeding back the actual on-off state of primary switchgear to the main control unit. The protection logic realizes interlock control, fault alarm and trip locking according to breaker position signals, preventing misoperation of protection functions caused by abnormal switch state collection.
Will replacing this binary input board erase the original relay protection fixed values?
Protection setting parameters and logic configuration are stored in the Flash memory of the main control board; replacing the BIM board will not modify any device configuration data, only power-on self-check is required after installation.
Are second-hand dismantled boards fully inspected before delivery?
All recycled used boards go through deep circuit cleaning, optocoupler performance screening, full-channel signal response test and long-time power aging test on professional test benches strictly to restore factory standard performance before shipment.
