About the Product
MTL4549 Dvojkanálový 4-20mA HART Signálový Konvertor
Dvojkanálové Riešenie pre Nebezpečné Oblasti
Konvertuje 4-20mA signály na bezpečné ovládanie HART zariadení v nebezpečných zónach 0/Div.1. Dva izolované kanály podporujú súčasnú prevádzku polohovačov ventilov, I/P konvertorov alebo iných poľných prístrojov.
Kľúčové Špecifikácie
- Kanály: 2 plne izolované
- Rozsah Signálu: 4-20mA (1mA pod/24mA nad rozsah)
- Zaťažovacia Kapacita: 800Ω na kanál (16V @ 20mA)
- HART Komunikácia: 500Hz-10kHz obojsmerná
- Presnosť: ±20µA pri 20°C (±1µA/°C posun)
- Čas Odozvy: 100ms do 200µA cieľa
Pokročilá Diagnostika
- MTL4549: Detekuje otvorené obvody (<0.9mA) AJ skraty (<50Ω)
- MTL4549C: Detekcia iba otvoreného obvodu (bez skratu)
- Vizuálny Stav: Zelená LED indikácia napájania
Technické Detaily
- Napájanie: 24V DC (max 70mA, 1.6W spotreba)
- Izolácia: 253V AC/DC medzi zónami
- Bezpečnostné Hodnotenia: Uo=28V, Io=93mA, Po=0.65W na kanál
- Certifikácie: Zóna 0, IIC, T4-T6; Div.1 Skupina A
Priemyselné Aplikácie
- Dvojité ovládanie ventilov v rafinériách
- HART-podporované tlakové prevodníky
- Redundantné bezpečnostné systémy
- Procesné riadiace slučky s diagnostikou
