NPEXA-C31T1

Analog input isolated barrier, it detects loop current and converts it from a hazardous area into 4~20mA and RS485 signals to a safe area by isolation. It needs an independent power supply. The input, output, and power supply are galvanically isolated from each other. Calibrate the apparatus or modify parameters by using a handheld programmer.
