Multifunction Instrction
Intelligent switchboard, switchgear
The SIEG meter is designed adopting the new microprocessor and digital signal processing technology. It gathers three-phase power measurement/display, energy accumulation, power quality analysis, fault alarm, digital input/output and network communication all in one. The product replaces a large number of traditional analog meters and can be used as front-end components for power monitoring systems (SCADA) for remote data collection and control. The RS-485 communication interface of industry standard uses Modbus-RTU communication protocol, which makes the networking easy and convenient, and it is an ideal choice for SCADA system integration. Two-way four-quadrant active power and reactive power of the energy accumulation can provide high-precision measurement data. The maximum / minimum recording function of embedded parameter and demand measurement function, with the master monitoring software can help users to count the energy consumption and load trends of every line, and automatically complete meter reading and generate a variety of power reports The abundant and flexible I/O function makes it fully qualified as the requirement of distributed RTU to realize teleindication, telemetering, remote control and measurement.
