TheT32isa2-wiretemperaturetransmitter.Dependingonthe
version,itcanbesuppliedwithvarioustypesofpowersupply.
Connectthepositivelineofthepowersupplytotheterminalmarked
with⊕,thenegativelineofthepowersupplytotheterminalmarked
with⊖.
Withexibleleadswerecommendtheuseofcrimpedconnector
sleeves.Theintegratedreversepolarityprotection(wrongpolarityon
theterminals⊕and⊖)preventsthetransmitterfromdamage.The
followingmaximumvaluesareapplicable:
■
ModelT32.xx.000:DC42V
■
ModelT32.xx.0IS:DC30V
■
ModelT32.xx.0NI:DC40V
TheT32.xStemperaturetransmitterrequiresaminimumterminal
voltageofDC10.5V.Theloadmustnotbetoohigh,asotherwise,in
thecaseofrelativelyhighcurrents,theterminalvoltageatthetrans-
mitterwillbetoolow.
TheT32isequippedwithterminalvoltagemonitoring('under-voltage'
detection).
Iftoosmallavoltageisdetectedattheterminal(<10V)theerroris
signalledontheoutput(<3.6mA).
