GS8500-EX Analogue Intrinsic Safety Barrier

2-wire (HART) transmitter, 3-wire transmitter, current source input isolated barrier, provide isolated power supplies for transmitters which located in a hazardous area. Transfer 4~20mA signal from hazardous area to safe area. 


It also allows bi-directional transmission of HART communication signals. This galvanic isolation barrier needs an independent power supply and galvanic isolation among power supply, input, and output.
