The Weidmüller EM122-RTU-2P is a single/three-phase energy meter with direct connection rated to 100A — no external current transformer required. It is designed for sub-metering distribution boards in commercial and industrial buildings, measuring active energy to Class 1 accuracy (IEC 62053-21) and communicating via RS485 Modbus RTU.
The meter supports both single-phase and three-phase circuit configurations from a single device, simplifying product selection. An LCD display provides local energy and power readings, and a pulse output is included for integration with pulse-counting inputs on third-party systems. Mounts on standard 72mm TS35 DIN rail.
