Two-wire system intelligent transmitter (HART), three-wire transmitter, current source input high distribution voltage detection terminal isolation type safety barrier, provide isolated power supply for transmitter in dangerous area, the 4~20Ma signal (or current source signal) generated by the transmitter is isolated and transmitted from the dangerous side to the safe side with 4~20Ma (or 1~5V) output, it also supports bidirectional transmission of HART digital signals. This product requires independent power supply and isolation of power supply, input and output.
