Isolated safety barrier/One_switch two_way read analog input isolated safety barrier

[Ex ia Ga] II C [Ex iaD] Dust explosion-proof certification products! Two-wire system intelligent transmitter (HART), three-wire transmitter, and current source input detection terminal are isolated by safety barrier, providing isolated power supply for transmitters in dangerous areas, 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, power supply, input and output isolation.
