PROTOCOLE HART
Une résistance de 250 Ω permet de convertir le signal 4-20 mA en signal 1-5 V Ce signal est relié à un Modem FSK qui assure la liaison avec le port série du PC |
Les caractéristiques techniques du protocole HART spécifient que l'impédance de la boucle – résistance du câble inclue – sont au minimum de 230 Ω et au maximum 1 100 Ω.
Hors de cette plage d'impédance, la communication HART ne fonctionne pas.
