Thermocouple Input Module imavomereza zolowetsa zisanu ndi zitatu kuchokera ku thermocouples ndikusintha mulingo wolowetsa wa chilichonse kukhala mtengo wa digito. Gawoli limathandizira mitundu yosiyanasiyana ya ma thermocouple, monga momwe zalembedwera mugawo la Module Specifications. Kulowetsa kulikonse kungathe kukonzedwa kuti kufotokoze zambiri monga millivolti kapena kutentha (gawo khumi la madigiri Celsius kapena Fahrenheit). Pamene ma thermocouples ayesedwa, gawoli likhoza kukhazikitsidwa kuti liyang'ane kutentha kwa thermocouple junction ndikuwongolera mtengo wolowera pamagulu ozizira. Polamulidwa kuchokera ku microprocessor yamkati ya module, gawo lolimba, lophatikizana ndi ma multiplexer limapereka mtengo wamakono wa analogi wazomwe zaperekedwa kwa analogi-to-digital converter. Chosinthira chimasintha mphamvu ya analogi kukhala ya binary (15 bits kuphatikiza chizindikiro) mtengo woyimira magawo khumi (1/10) a madigiri Celsius kapena Fahrenheit. Zotsatira zake zimawerengedwa ndi microprocessor ya module. Microprocessor imazindikira ngati zomwe zalowetsazo zatha kapena pansi pamtundu wake wokhazikika, kapena ngati pali mawonekedwe otseguka a thermocouple. Pamene gawoli lakonzedwa kuti liyeze ma millivolts m'malo mwa zolowetsa kuchokera ku thermocouples, zotsatira za kutembenuka kwa analogi-to-digital ndi mtengo womwe umanenedwa mu hundredths (1/100) ya mamilivolti. Bus Interface Module imayang'anira kusinthana kwa data yonse ya I/O ya ma module mu I/O Station pa basi yolumikizirana. Chithunzi chomwe chili pansipa chikuyimira ntchito zazikulu za module ya Thermocouple.
