À propos du produit
MTL4549 Convertisseur de signal HART 4-20mA à double canal
Spécifications principales
• Canaux : 2 voies isolées 4-20mA
• Support HART : bidirectionnel 500Hz-10kHz
• Capacité de charge : 800Ω par canal (16V @ 20mA)
• Précision : ±20µA @ 20°C (dérive ±1µA/°C)
• Détection de défaut : circuit ouvert/court-circuit (MTL4549Y = circuit ouvert uniquement)
Points forts de performance
• Temps de réponse : 100ms pour se stabiliser dans 200µA
• Ondulation : <40µA p-p signal sans bruit
• Classe de sécurité : Zone 0 IIC / Div.1 Groupe A
• Alimentation : 24V DC (70mA max, dissipation 1,6W)
Différences clés
• MTL4549 : détecte à la fois les circuits ouverts (chute de 0,5mA) ET les courts-circuits (<50Ω)
• MTL4549Y : détection uniquement de circuit ouvert (pas de court-circuit)
Applications typiques
• Positionneurs de vannes doubles dans les raffineries
• Transmetteurs de pression compatibles HART
• Boucles de contrôle redondantes avec surveillance des défauts
• Systèmes de sécurité nécessitant une isolation à double canal
Certifications de sécurité
• Uo=28V, Io=93mA, Po=0,65W par canal
• Isolation Um=253V AC/DC
• Classe de température T4-T6
