The PZ series electric energy meter adopts AC sampling technology, which can directly or indirectly measure electrical parameters such as current and voltage, power, and electric energy in three-phase power grids.It can be used for local display and can also be connected to industrial control equipment to form a measurement and control system. The product complies with the enterprise standard PZAccording to the regulations of "Series Communication Programmable Digital Intelligent Meter".The instrument has an RS-485 communication interface and is compatible with Modbus RTU protocol; Can convert the power signal into standard analog output; Can bring fourTwo way switch input/two way switch output. According to different requirements, set parameters such as transformation ratio, alarm, and communication through the dashboard buttonsAnd control.The performance price ratio of PZ series instruments can directly replace conventional power transmitters and measuring instruments. As an advanced intelligent and digital technologyThe digital front-end acquisition component of this power instrument has been widely used in various control systems, SCADA systems, and energy management systems.
