Description of operation
TheSI120isasignalisolatordesignedto
eliminatepotentialgroundloopproblems
prevalentin4-20mAcontrolloops.Itcanalso
beusedinotherapplicationswheregalvanic
isolationisarequirement.Theunitincorporates
twoisolated24Vdcpowersuppliesforinput
andoutputloopsallowingittobeusedwith
mainsand/orlooppoweredtransmitandreceive
instrumentswithouttheneedforadditional
powersupplies.Bothpowersuppliesarecurrent
limitedat30mA.Isolationisachievedbytheuse
ofanopto-couplercurrentmirrorcircuit.
