DJZY102-2 Rack Mount DC Electrical Energy Monitor
General introduction:
DJZY102-2 rack mount DC electrical energy monitor integrates measurement, electric energy metering, teleindication and telecontrol, LCD display and network communication, which can measure DC voltage and current, power and other parameters of the grid, as well as positive and negative DC electric energy. The monitor is equipped with RS-485 communication interface supporting MODBUS-RTU and DL/T645-2007 dual communication protocol. With switch input and output function, the monitor can realize analog transmission output as well.
Our monitor complies with the following criteria:
1. Q/OKRW 016-2014 electronic DC energy meter.
2. ZB Y318—85 technical specifications of electronic DC watt-hour meter.
3. JJG842—1993 verification conditions of DC electric energy meter.
4. DL/T645-2007 communication protocol of multifunctional electric energy meter.
5. MODBUS-RTU communication protocol.
