Allen-Bradley 1794-OF4I FLEX I/O Isolated Analog Output Module

Allen-Bradley 1794-OF4I adalah modul FLEX I/O Isolated Analog Output dari Rockwell Automation yang menyediakan 4 channel analog output terisolasi. Modul ini dirancang untuk sistem 1794 FLEX I/O, FLEX Ex, dan FLEX XT I/O, dengan resolusi hingga 15 bit plus sign. 1794-OF4I mendukung aplikasi kontrol industri yang membutuhkan sinyal analog voltage maupun current dengan isolasi antar channel dan terhadap sistem. Produk ini berstatus Active Mature menurut Rockwell Automation.

Allen-Bradley 1794-OF4I menyediakan pilihan output current 4–20 mA atau 0–20 mA serta output voltage ±10 V, 0–10 V, ±5 V, dan 0–5 V. Setiap channel dapat digunakan untuk perangkat output 2-wire, 3-wire, maupun 4-wire. Modul menggunakan konversi digital-to-analog converter (DAC), dengan conversion/update rate 2,5 atau 5,0 ms untuk seluruh channel dan step response kurang dari 25 µs hingga 63% full scale.

Untuk kebutuhan otomasi dan distributed I/O, 1794-OF4I menggunakan catu daya 24 V DC dan memiliki akurasi absolut hingga 0,1% full scale pada 25 °C. Output voltage dapat menangani beban resistif hingga 750 Ω dengan current load maksimum 3 mA, sedangkan output current mendukung konfigurasi 4–20 mA dan 0–20 mA. Modul memiliki perlindungan dan isolasi yang sesuai untuk aplikasi industri, dengan rentang temperatur operasi -20 hingga 55 °C pada spesifikasi produk Rockwell Automation.
