About the Product
MTL4549 Dvokanalni 4-20mA HART Signalni Pretvarač
Rješenje za opasna područja s dva kanala
Konvertira 4-20mA signale za sigurno upravljanje HART uređajima u opasnim zonama Zone 0/Div.1. Dva izolirana kanala podržavaju istovremeni rad pozicionera ventila, I/P pretvarača ili drugih terenskih instrumenata.
Ključne specifikacije
- Kanali: 2 potpuno izolirana
- Raspon signala: 4-20mA (1mA ispod/24mA iznad raspona)
- Kapacitet opterećenja: 800Ω po kanalu (16V @ 20mA)
- HART komunikacija: 500Hz-10kHz dvosmjerna
- Točnost: ±20µA na 20°C (±1µA/°C drift)
- Vrijeme odziva: 100ms do unutar 200µA cilja
Napredna dijagnostika
- MTL4549: Detektira i prekide (<0.9mA) I kratke spojeve (<50Ω)
- MTL4549C: Detekcija samo prekida (bez kratkog spoja)
- Vizualni status: Zelena LED dioda za napajanje
Tehnički detalji
- Napajanje: 24V DC (maks. 70mA, disipacija 1.6W)
- Izolacija: 253V AC/DC između zona
- Sigurnosne ocjene: Uo=28V, Io=93mA, Po=0.65W po kanalu
- Certifikati: Zona 0, IIC, T4-T6; Div.1 Grupa A
Industrijske primjene
- Upravljanje dvostrukim ventilima u rafinerijama
- HART omogućen prijenosnici tlaka
- Redundantni sigurnosni sustavi
- Procesne kontrolne petlje s dijagnostikom
