NPEXA-K01

Temperature input isolated barrier, it converts the thermocouple/thermal resistance signals from a hazardous area into 4~20mA signals to a safe area by isolation. It has external cold junction compensation terminals. It needs an independent power supply. The input, output, and power supply are galvanically isolated from each other.
