Product Description
EX4Z31 is a intelligent three-phase electrical parameter data acquisition measurement indicator EX4Z31 mapping; three meter method has accurate measurement and on-site display electrical parameters of three-phase three wire and three-phase four wire system alternating current circuit of three-phase current, three-phase voltage (RMS), active power, reactive power, power factor, frequency, positive and negative active power, positive and negative directed power supply. And with 2 switch input and 1 way to set the relay alarm output.
The input (0-500v) three-phase voltage, three-phase current 0-500A; output for RS-485 or RS-232 interface of the digital signal and support the communication protocol has four: (ASCII) Advantech Adam compatible communication protocols, hexadecimal LC-04 protocol, MODBUS-ASCII, Modbus RTU.
EX4Z31 type instrument can be widely used in all kinds of industrial control and measurement system and all kinds of distributed power control system.
Using electromagnetic isolation and photoelectric isolation technology, the voltage input, the current input and output of the three side completely isolated.
Product introduction
