Slim Type Thermocouple Temperature 4 20ma Signal Isolation Converter
Description Slim Type Thermocouple Temperature 4 20ma Signal Isolation Converter
The isolation converter provides isolated working power to the transmitter in the field, and detects the
The current/voltage signal, after transformation, outputs an isolated current/voltage signal, realizing
Three-terminal isolation between input, output and power supply.
