ABB 1MRK002133-ABR02: Dual RJ45, IEC 61850 GOOSE/Modbus TCP, REF615/RET670 Compatible

Technical Specifications

Main Features and Advantages

Three-in-one: ADC front-end + protection engine + communication gateway:​ Most ABB spares we have covered so far—P4LG carrier, P3LG drive board, 1MRK000173-BBR03 binary I/O—are single-role. The ABB 1MRK002133-ABR02​ is unusual in packing all three layers of a protection IED onto one PC board: the 22-channel, 16-bit dual-ADC stage with PGA and ±100 ns IRIG-B/PTP sync does the metering and fault-recording capture; the on-board algorithm engine runs the protection curves (overcurrent速断/定时限/反时限, ground fault, distance, differential depending on IED personality); and the dual RJ45 port pushes IEC 61850 GOOSE/MMS and Modbus TCP up to the SAS. That integration is why “1MRK002133-ABR02” shows up in spare catalogs tagged both as “line protection module” and as “communication expansion”—it is both.Relion 615/670 ecosystem fit:​ The 1MRK002133-ABR02​ is the board-level answer when a REF615 medium-voltage feeder protection relay, a RET670 transformer protection IED, or a REG670 line-protection IED needs its internal processing board replaced. Because the same 002133 PCB DNA appears across these IED types with firmware differentiation, a spare purchased as “1MRK002133-ABR02” can serve multiple host models—provided the firmware image flashed onto it matches the host. This is the board’s main “gotcha” and its main value: one spare SKU backing multiple IED types in a utility’s relay fleet.±100 ns time synchronization for PMU-grade sampling:​ The ABB 1MRK002133-ABR02​ is not a protection board that tolerates sloppy sampling. The IRIG-B and PTP (IEEE 1588) sync path, the dual 16-bit ADC running 100 kSPS, and the multi-channel simultaneous sampling are all there to satisfy phasor measurement and fault-location accuracy—critical when the question after a trip is “lightning strike or tree fault?” and the waveform record needs to hold up in a protection-performance audit.IEC 61850 GOOSE ≤ 5 ms in a变电站 EMI envelope:​ The RJ45 ports aren’t an afterthought—they carry GOOSE peer-to-peer tripping between IEDs in a bay, and the 1MRK002133-ABR02​ is specified to keep GOOSE latency at or below 5 ms even with the EMI, voltage dip, and transient environment of a 110–500 kV substation. 3750 V DC isolation on the analog side and the conformally coated PCB (within the IED chassis, IP54 housing-level for RET670) are the reasons the board survives what would kill an office-grade NIC.-40°C to +70°C, MTBF ≥ 400k hours:​ Utility specs drive this. Outdoor substations, desert solar-inverter stations, Arctic transmission corridors—the ABB 1MRK002133-ABR02​ is specified for the full industrial-extended band, and the MTBF number (≥ 400,000 hours, ~45 years at 40% duty) is the figure asset managers quote when justifying “keep two on the region shelf.”PCM600-configurable, firmware-sensitive:​ The board itself carries Flash and runs the IED application image. Swapping a 1MRK002133-ABR02​ into a REF615 that expects a different firmware stepping will throw a mismatch. The upside: once the right image is on it (or the host re-downloads), the board disappears into the IED for another decade. This is exactly parallel to the P3LG drive board behavior we covered earlier—ABB spares with Flash are “matched spare” items, not “grab any off the bin” items.
