Redundansi Modular Tiga Kali dan Isolasi Galvanik

Dalam platform SIS Triconex, 3721 beroperasi dalam arsitektur TMR 2oo3, di mana setiap jalur memperoleh data analog secara independen sebelum logika voting menentukan nilai akhir sistem. Isolasi galvanik dan input diferensial terkopel DC menekan interferensi antarsaluran, sementara penolakan mode umum modul sebesar -85 dB mempertahankan integritas sinyal dalam kondisi gangguan industri. Perlindungan di luar rentang hingga 150 VDC/115 VAC memastikan perilaku yang stabil selama gangguan kabel atau lonjakan transien.

Pertanyaan yang Sering Diajukan

T: Apakah 3721 dapat diganti saat sistem bertegangan? J: Ya. Modul ini mendukung kemampuan hot-swap dalam sasis Tricon yang bertegangan.

T: Apakah pemilihan resolusi 12-bit atau 14-bit memengaruhi waktu pembaruan? J: Tidak. Interval pembaruan 10 ms berlaku sama untuk kedua mode resolusi.

T: Bagaimana modul menangani derau mode umum? J: Input diferensial terkopel DC dan CMRR -85 dB menekan derau antara DC dan 100 Hz.

Panduan Instalasi Lapangan

  • Pertahankan torsi yang tepat pada sekrup terminal untuk mencegah pergerakan konduktor akibat getaran.
  • Rutekan kabel analog secara terpisah dari konduktor berenergi tinggi untuk mengurangi derau induksi.
  • Hubungkan pelindung pada satu titik pembumian untuk menghindari arus sirkulasi.
  • Pastikan modul terpasang dengan benar di dalam sasis Tricon sebelum diberi tegangan.
  • Hindari tekukan tajam pada kabel analog untuk mempertahankan impedansi dan integritas isolasi.
