PZ7777-series digital Voltmeter

Summary&application: 

PZ7777-series digital Voltmeter is the new generation of programmable intelligent instrument, integrating measurement, alarm, transmission, communication, mainly applied into real-time measurement and indication for the voltage in the electrical circuit. It can output the limit-value alarming output for the measurement value according to the settings, and conduct transmitting output for the measured electrical quantity data, realizing networked through RS485 communication interface and host computers.


1. Main functions and characteristics:

◆Real-time measurement and indication for the current/voltage value in the circuit.

◆Extendible for one-way analog quantity output function, with various transmitting specifications optional and extendible for switch quantity output function of relay. It can realize upper/lower-limit alarm output, extendible for RS-485 communication interface, adopting 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.
