The Senva EMX-IP is a revenue-grade True RMS electrical energy meter (ANSI C12.20 Class 0.2, 0.2% meter accuracy) with native BACnet IP and Modbus TCP/IP over 10/100 Base-T Ethernet, a color OLED display, data logging, and 2 pulse inputs. It is self-powered from 1 to 3 phase service (90–600V), monitors loads from 0.25 to 6000A using any 0.333V CT or metering Rogowski coil, mounts on PR30 DIN rail, and is made in the USA by Senva, Inc. (Buy American Act, BABAA, ARRA, and TAA conformant).
Senva EMX-IP True RMS Energy Meter for BACnet IP & Modbus TCP/IP
The Senva EMX-IP brings the EMX revenue-grade metering platform directly onto the building’s IP network — no RS-485 trunk, no gateway. With native BACnet IP and Modbus TCP/IP over 10/100 Base-T Ethernet, the EMX-IP integrates straight into modern BAS architectures and IT-managed networks. SenvaSync app setup over NFC works even while the device is powered off, and the meter is line-powered from the monitored service with no separate power supply.
Like the rest of the EMX family, the EMX-IP accepts any 0.333V CT or standard metering Rogowski coil without external integrators, and its 2 pulse inputs relay additional meters (water, gas, steam) onto the network. True RMS measurement maintains 0.2% ANSI C12.20 Class 0.2 accuracy on heavily distorted, harmonic-rich loads.

Frequently Asked Questions
Is the Senva EMX-IP a revenue-grade meter?
Yes. The EMX-IP meets ANSI C12.20 Class 0.2 standards (0.2% meter accuracy), commonly referred to as ANSI revenue grade, making it suitable for tenant submetering and billing applications.
What protocols does the EMX-IP support?
The EMX-IP communicates over BACnet IP and Modbus TCP/IP on a 10M/100M Base-T Ethernet connection. It does not have an RS-485 port — for BACnet MS/TP or Modbus RTU/ASCII, use the standard EMX or EMX-L.
Does the EMX-IP have pulse outputs?
No. The EMX-IP omits the pulse outputs found on the EMX and EMX-L; energy data is delivered over the network instead. It retains 2 pulse inputs (7 ± 0.5 VDC rating) for aggregating additional water, gas, or steam meters.
Does the EMX-IP work with my existing CTs?
Yes. The EMX-IP accepts any standard 0.333V output CT as well as standard metering Rogowski coils, with no external integrators required.
Does the EMX-IP need a separate power supply?
No. The EMX-IP is self-powered from the monitored line voltage, accommodating 1 to 3 phase service from 90VLN to 600VLL.
Is the Senva EMX-IP Buy American Act compliant?
Yes. The EMX series is manufactured in the USA by Senva in Beaverton, Oregon, and conforms to the Buy American Act, Build America Buy America Act (BABAA), ARRA Section 1605, and the Trade Agreements Act (TAA). The signed 2026 conformance declaration is available in the documentation section above.
