Analog Input Tranzorb Failure

AcommoncauseofAnalogInputTranzorbFailureonAna-

logInputsModel2,3,4&5:Ifa4-20mAcircuitisinitially

wiredwithlooppower,butwithoutaload,theanaloginput

couldsee24VDC.Thisishigherthantheratingofthetran-

zorb.ThiscanbesolvedbyNOTconnectinglooppower

priortoloadconnection,orbyinstallingalow-costPTCin

seriesbetweentheloadandanaloginput.
