M31-XAXA0404G Module IO distant distribué pour l'acquisition de signaux analogiques et numériques, compatible avec le protocole Modbus standard, modulable et facilement extensible
[Interface de communication]：RJ45, RS485
[Tension de fonctionnement]：DC 9 ~ 36 V
[Poids du produit]： 170 ± 5 g.
[Introduction]：La série M31 de maîtres IO distribués prend en charge les protocoles Modbus TCP et RTU, permet l'accès simultané de 5 clients et est compatible avec les codes de fonction 01, 02, 03, 04, 05, 06, 15 et 16.La coque adopte un revêtement à trois niveaux : antifongique, anti-humidité et anti-sel. Son design extensible permet de connecter jusqu'à 16 modules d'extension IO selon les besoins, sans nécessiter l'achat d'un système complet, ce qui permet d'économiser les coûts et facilite l'intégration sur site. L'appareil intègre une fonction de diagnostic d'état, surveillant en temps réel l'état des communications.
