Dual-Load 3-Phase Energy Meter CT Input, Modbus RTU

The Weidmüller EM124-RTU-2L is a multifunction power meter that simultaneously measures two separate three-phase circuits — replacing what would otherwise require two individual meters. It has been engineered specifically for split load distribution boards in commercial buildings where power and lighting circuits must be measured independently to support NABERS or equivalent energy efficiency ratings.

The EM124-RTU-2L uses innovative plug-and-play 3-phase current transformer (CT) blocks that connect back to the meter via a simple RJ12 cable, eliminating the risk of CT wiring errors. Measured parameters include V, A, W, VA, VAR, PF, THD, frequency, kWh, and demand. RS485 Modbus RTU supports daisy-chain connection of up to 64 devices. CT options (125A, 150A, 250A) are available separately.
