1、 Performance Overview

Convert the current signal from the safe area into a 4mA to 20mA current signal through isolation and output it to the hazardous area. On site equipment such as electrical converters and valve positioners that can control hazardous areas. The three terminal isolation of input, output, and power supply has the advantages of fast response, low power consumption, and good temperature characteristics.
