WP8000-EX series repeat-type zener barrier is not only completed with Two-wire transmitters, electrical converters, electrical valve positioner, solenoid valves, alarm, liquid level switches, etc. but also completed with two-wire smart transmitter, two-wire smart valve positioner, intelligent electromagnetic flowmeters to realize high-precision analog signal transmission.
It can restrict dangerous energy enter into dangerous place from intrinsically safe terminals and convert 4～20mADC signal to 4～20mADC（1～5VDC）signal. The different from other zenor barrier is that when the dangerous energy is disappeared, they can work normally again.
