NPEXB-HM31
1 input and 1 output contrast
Analog output isolated barrier, it transfers 4~20mA signals from a safe area to a hazardous area. It allows transmission of HART communication signals. It needs a backplane power supply. The input, output, and power supply are galvanically isolated from each other. The LFD function of output short-circuit/ line-break can be closed by the DIP switch on the front side.
NPEXB-HM3D11
