HART communicationoutput.®
5.1.1 HCUanalogoutputcharacteristics
Theanalogoutputispassive,henceanexternalpowersupplyisrequired.Thevoltageoftheloopsupplyshouldbeatleast12Vdc,andmaynotexceed64Vdc(measuredattheterminalsofthegauge).
Theloopresistanceisthetotalresistancefromtheloop,andhenceincludessupplyoutputresistance,totalcableresistance(includingseriesresistor)andtheinputresistancefromreaderoranaloginput.

Theanalogoutputcanbeseteitherpassiveoractive(refertosection5.2.1).Whensettoactive,thesupplyvoltageintheloopis:20Vdc(±5%).
Thevoltageoftheloopsupplyshouldbeatleast8Vdc,andmaynotexceed64Vdc(measuredattheterminalsofthegauge).Supplyvoltagesover30Vdcrequireanexternalseriesresistor(refertofigure5.1B).
