Isolator Pemancar HART Saluran Ganda MTL4544
Kondisi Sinyal Saluran Ganda untuk Area Berbahaya
MTL4544 menyediakan dua saluran isolasi independen untuk pemancar 4-20mA/HART 2-kawat atau 3-kawat di lokasi berbahaya Zona 0/Div. 1. Solusi intrinsik aman ini memberikan daya pemancar 16,5V sambil mempertahankan kemampuan komunikasi HART penuh.
Fitur Utama
- Dua saluran 4-20mA yang sepenuhnya terisolasi dengan transparansi HART
- Daya keluaran 16,5V memberi daya pada pemancar lapangan pada 20mA
- Mendukung beban hingga 450Ω di area aman (20mA)
- Waktu respons ultra-cepat 50μs untuk proses kritis
- Perangkat sederhana bersertifikat untuk instalasi mudah
Spesifikasi Teknis
- Rentang Input/Output: 0-24mA (4-20mA nominal)
- Pasokan Pemancar: 16,5V pada 20mA per saluran
- Akurasi: ±15μA pada 20°C (±0,8μA/°C drift)
- Kapasitas Beban: 450Ω @ 20mA per saluran
- Konsumsi Daya: 1,4W @ 24V DC
- Rating Keamanan: Uo=28V, Io=93mA per saluran
- Sertifikasi: ATEX, IECEx Zona 0 IIC
Aplikasi Tipikal
- Antarmuka pemancar pintar HART
- Monitoring kepala sumur minyak dan gas
- Instrumentasi pengolahan kimia
- Sistem pengukuran level tangki
- Kontrol pembakar dan boiler
MTL4544 memenuhi semua persyaratan keselamatan intrinsik sesuai IEC 60079-11, menyediakan isolasi sinyal yang andal untuk pengukuran proses kritis di atmosfer yang mudah meledak.
