Functional specifications
MDSF1 - AI4 detection terminal distribution type safety barrier for the dangerous sites (HART) to work power source to provide 2 wire system of transmitter, and sampling of the transmitter output current signal (compatible with HART), after separation output to the DCS/PLC. The working power is taken from the output loop and does not require an independent power supply. Explosion-proof grade Exib Gb Ⅱ C. You can choose 1 out of 1 and 2 out of 2.
