Isolated safety barrier/two_in and two_out analog output 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 to provide isolated power supply for transmitters in dangerous areas. The 4 ~ 20mA (or 1~5V) output generated by the transmitter, it also supports bidirectional transmission of HART digital signals. This product requires independent power supply and three isolation of power input and output.
