Product Isolated Barrier NPEXA-C271

NPEXA-C271

Temperature input isolated barrier, it converts the thermal resistance signals from a hazardous area into 1:1 resistance and 4~20mA 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.
