Product Overview: MR Messko D1272AT 663-BBAAAF (MTRAB)

Parameter Specification
Manufacturer Maschinenfabrik Reinhausen / Messko GmbH, Germany
Model Number D1272AT
Type Code 663-BBAAAF
Product Family MTRAB
Device Type Digital Multifunction Transformer Protection & Monitoring Relay

Application & Fault Scenarios

Typical Uses: Substation power transformer protection, OLTC condition-based maintenance, SCADA integration for grid assets.
Common Field Issues:
  • False thermal trip → verify RTD wiring resistance and ambient compensation offset
  • Modbus timeout → confirm baud rate parity match and shield grounding at one end only
Note: Firmware version determines available IEC 61850 data sets; always check revision before commissioning in new substation automation systems.

FAQ

Q1: What does "663-BBAAAF" indicate in MR Messko D1272AT?
A: It is the type code defining hardware variant: "BB" = 8 RTD + 4 mA inputs, "AA" = standard relay output set, "AF" = Modbus RTU + RS-485; other suffixes denote different I/O or communication options.
Q2: Can D1272AT replace legacy Messko TRASY2 monitoring relay?
A: Yes — MTRAB is the designated successor; use Migration Assistant in ConfigTool to map TRASY2 parameters, but verify OLTC mechanical linkage compatibility separately.
Q3: Does this unit support IEC 61850 GOOSE messaging?
A: Only with optional Ethernet module and firmware ≥ V3.2; base RS-485 version supports Modbus RTU only — specify communication option at time of order.
