Multi-Functional Digital Panel Meter (PD7777)

Product Description

PD7777 multi-functional digital panel meter
Function: Has programmable measurement\display\digital communication, etc. Many functions, it's mainly used in measuring and analyzing several electrical parameters. It can realize the display and teletransmission of electrical parameters through RS485 data interface communicating with the external device.

Function expansion: 4-way analog output(0~20mA/4~20mA) can realize transmitting output function of electricity; 4-way switch input and 4-way switch output can realize local/remote switch signal detection and control output function("remote communication" and "remote control"functions). You can program and set parameters including transformer rate\upper and lower limit alarm value\communication address of the meter\communication baud rate\transmitting output method\transmitting output range, etc. By pressing the programmable keys on the panel.
