For reference, the followings are the general technical parameters for Analog Input Type Isolated Safety Barrier
Model: NPEXA-KM31
Input: 4~20mA
Output: 4~20mA
Description
This Isolated Safety Barrier detects loop current and converts it from a hazardous area into current or voltage signals to a safe area by isolation and provides transmitter with power in the hazardous area. It allows transmission of HART communication signals. The input, output and power supply are galvanically isolated from each other
