Product Description

19D-NX Modbus energy meter is Blue Jay's next-generation din-rail meter power meter. Using a 3M width expand model can build a max 40x3P4W or 120x1P2W energy metering system. A flexible selection of different modules can build the most suitable on-site integrated metering device. The 19D-NX din rail dc power meter uses CTs connect, and provides max 0.5 class metering accuracy. The default is RS485 Modbus-RTU port so it can be called an energy meter with RS485. Furthermore, the customized expand module of the 240v electric meter can provide extra IoT modules valid for different projects.
