NPEXA-CM17

Millivolt input isolated barrier, it transfers the millivolt signals from a hazardous area to a safe area. It needs an independent power supply. The input, output, and power supply are galvanically isolated from each other. It has the function of setting over range output when the input is disconnected.

Input signal

Millivolt(-100~100mV)

Output signal

1 : 1

Channels

1 input/1 output

Power Supply Mode

24VDC terminal power supply
