- Description
The ABB 2TAZ665054R2000 (D1M 20 Ethernet) is a DIN-rail power meter for 1-phase or 3-phase systems with Modbus TCP/IP over RJ45, accepting 1 A or 5 A current inputs up to 300 V AC. It delivers Class 0.5 active-energy accuracy per IEC 61557-12, tighter than a Class 1 multimeter, with an LCD display and 2 digital inputs plus 2 digital outputs.

Selection Notes
Class 0.5 accuracy on the D1M 20 Ethernet is tighter than the Class 1 rating used on simpler multimeters in this range, which matters for revenue-grade or sub-billing measurement. Modbus TCP/IP over RJ45 integrates directly into an Ethernet network rather than requiring an RS-485 bus and gateway. Choose the RS-485 Modbus RTU variant of this power meter instead when the panel only has a serial bus available.
