[Introduction]：La série d'hôtes d'E/S distribués LoRa est un puissant dispositif de contrôle à distance et d'acquisition de données sans fil. Utilisant la technologie sans fil LoRa (avec module sans fil intégré), ce dispositif d'E/S LoRa peut être contrôlé par l'envoi de commandes Modbus RTU via un port série ou un périphérique réseau LoRa distant. Il peut être utilisé avec notre radio de transmission de données sans fil (E95-DTU (900SL30)) pour acquérir et contrôler sans fil les signaux d'entrée et de sortie numériques et analogiques (DI/DO/AI/AO). Le boîtier du produit est recouvert d'un revêtement conforme, offrant une résistance à la moisissure, à l'humidité et au brouillard salin.
