NPEXA-H61A1P2

Frequency input isolated barrier, it converts the frequency signals from a hazardous area into 4~20mA signals to a safe area by isolation, a relay alarm output. It needs a backplane 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.
