The YY204Z series comprehensive power monitoring instrument is designed for the power monitoring needs of power systems, industrial and mining enterprises, public facilities, and intelligent buildings. It can measure all commonly used power parameters with high precision, such as three-phase voltage, current, active power, reactive power, frequency, power factor, four quadrant electrical degree, etc. It uses a large LCD screen to display the instrument measurement parameters and the operation status information of the power grid system. The instrument surface board has four programming keyboards, and users can easily switch displays and program parameters on site, with strong flexibility.

The YY204Z series comprehensive power monitoring instrument has multiple output modes for expansion functions to choose from: the RS485 digital interface can achieve instrument network communication function; Two electrical pulse outputs and one or four analog outputs (4-20mA) can achieve the function of transmitting and outputting electrical energy and quantity; The functions of 4-way or 6-way switch input and 2-way or 4-way switch output can achieve local or remote switch signal monitoring and control output ("remote signaling" and "remote control" functions).

The YY204Z series comprehensive power monitoring instruments have a very high cost performance ratio, which can directly replace conventional power transmitters, measuring and indicating instruments, energy metering instruments, and related auxiliary units. They have the characteristics of easy installation, simple wiring, easy maintenance, small engineering quantity, on-site programmable input parameters, and the ability to complete networking of different PLC and industrial control computer communication software in the industry. As an advanced intelligent and digital front-end data acquisition component of the power grid, the PD204Z series comprehensive power monitoring instruments have been widely used in various control systems, SCADA systems, and energy management systems.
