The WattNode® Module for Modbus® is a kilowatt hour (kWh) energy and power meter with ANSI C12.1 and ANSI C12.20 class 0.5 accuracy. Designed for easy customization for nearly any application or type of equipment, the WattNode Module provides bidirectional energy and power readings via an RS-485 port using Modbus RTU communications.  The WND-M1-MB meter measures 1, 2, or 3 phases, in delta or wye services, from 120 to 600 Vac. It is packaged in a compact, DIN-rail mount enclosure. Current transformers are available in various opening sizes with ratings from 5 to 6,000 amps. The Module is instrument powered from 6-24 Vdc or from an isolated 12-24 Vac control transformer.  The optional MDR-10-12  can power up to 12 WND-M1-MB meters.
