About the Product
MTL4549 Dual-Kanal 4-20mA HART Signalwandler
Dual-Kanal Lösung für explosionsgefährdete Bereiche
Wandelt 4-20mA Signale um, um HART-Geräte in Zone 0/Div.1 explosionsgefährdeten Bereichen sicher zu steuern. Zwei isolierte Kanäle unterstützen den gleichzeitigen Betrieb von Ventilstellern, I/P-Wandlern oder anderen Feldgeräten.
Wichtige Spezifikationen
- Kanäle: 2 vollständig isoliert
- Signalbereich: 4-20mA (1mA Unter-/24mA Überbereich)
- Lastkapazität: 800Ω pro Kanal (16V @ 20mA)
- HART-Kommunikation: 500Hz-10kHz bidirektional
- Genauigkeit: ±20µA bei 20°C (±1µA/°C Drift)
- Ansprechzeit: 100ms bis auf 200µA des Zielwerts
Erweiterte Diagnostik
- MTL4549: Erkennt sowohl offene Schaltungen (<0,9mA) ALS AUCH Kurzschlüsse (<50Ω)
- MTL4549C: Nur Erkennung offener Schaltungen (kein Kurzschluss)
- Visueller Status: Grüne Power-LED
Technische Details
- Stromversorgung: 24V DC (max. 70mA, 1,6W Verlustleistung)
- Isolation: 253V AC/DC zwischen Zonen
- Sicherheitsbewertungen: Uo=28V, Io=93mA, Po=0,65W pro Kanal
- Zertifizierungen: Zone 0, IIC, T4-T6; Div.1 Gruppe A
Industrielle Anwendungen
- Doppelventilsteuerung in Raffinerien
- HART-fähige Drucktransmitter
- Redundante Sicherheitssysteme
- Prozessregelkreise mit Diagnostik
