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.
◆Real-time measurement and indication for the 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.
After-sale service: within 18 months after delivery, provides local service or on-site installation and training service depends on the market
