NPEXB-HM3D11
2 inputs and 2 outputs 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.
NPEXB-KM31
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. The input, output, and power supply are galvanically isolated from each other. Besides, the LFD (line fault detection of field connections) function of output circuit is available.
