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.
