NPEXA-C21L

Temperature input isolated barrier, it converts the resistance signals from a hazardous area into 4~20mA signals to a safe area by isolation. It has loop powered. The input and output is galvanically isolated from each other. Calibrate the apparatus or modify parameters by using a handheld programmer.
