[Introduction]：ME31-XDXX0400 est un module d'acquisition de température à résistance thermique PT100, qui dispose d'une fonction d'acquisition de température PT100 à 4 canaux et prend en charge l'acquisition de capteurs de température PT100 à 2/3 fils.La coque adopte un revêtement à trois niveaux : antifongique, anti-humidité et anti-sel. Il dispose également d'un écran d'affichage pour faciliter le débogage, la configuration et la visualisation de la température sur site. Le module d'acquisition de température prend en charge les interfaces de communication réseau et RS485, et prend en charge le protocole Modbus TCP ou Modbus RTU pour l'acquisition. Il peut également être utilisé comme passerelle Modbus pour envoyer automatiquement des commandes avec des adresses Modbus non natives via le port série/port réseau. Il prend en charge la conversion des protocoles Modbus TCP et Modbus RTU pour faciliter l'extension des appareils esclaves Modbus.
