MTL4549 Konverter Sinyal HART 4-20mA Saluran Ganda

Solusi Area Berbahaya Saluran Ganda

Mengubah sinyal 4-20mA untuk mengendalikan perangkat HART dengan aman di lokasi berbahaya Zona 0/Div.1. Dua saluran terisolasi mendukung operasi simultan posisi katup, konverter I/P, atau instrumen lapangan lainnya.

Spesifikasi Utama

  • Saluran: 2 terisolasi penuh
  • Rentang Sinyal: 4-20mA (1mA di bawah/24mA di atas rentang)
  • Kapasitas Beban: 800Ω per saluran (16V @ 20mA)
  • Komunikasi HART: 500Hz-10kHz dua arah
  • Akurasi: ±20µA pada 20°C (±1µA/°C drift)
  • Waktu Respon: 100ms hingga dalam 200µA dari target

Diagnostik Lanjutan
