Summary&application: PZ7777-□S series three phase digital Voltmeter is the new generation of programmable intelligent instrument, mainly applied into real-time measurement and indication for the phase voltage, wire voltage in the three phase electrical circuit, realizing remote data for the measured electrical quantity data through RS485 interface or analog quantity transmission interface.
◆Real-time measurement and indication for the phase voltage and wire voltage value in the electrical circuit.
◆Extendible for one-way analog output function, with optional transmitting specifications of 4-20mA, 0-20mA and 0-10mA.
◆Extendible for relay switch quantity output function, to realize the upper and lower limit alarming output.
◆Extendible for RS-485 communication interface, adopting the standard ModBus-RTU communication protocol and the baud rate can be set.
◆The instrument is characterized with parameters such as range, upper/lower-limit alarm value, alarm return difference, communication address of the meter, baud rate, transmitting output mode, etc. are programmable.
