The ICF-1280I-S-ST-T is a rugged fiber optic PROFIBUS converter from the ICF-1280I Series, equipped with two single-mode ST connectors. With a wide operating temperature range of -40 to 75 °C, this device is designed for extreme industrial conditions. It reliably transmits PROFIBUS DP signals at speeds up to 12 Mbps over long distances, making it ideal for applications with stringent EMI shielding requirements.

The unit features built-in 2 kV isolation, dual redundant power inputs, and compact DIN-rail mounting in a durable metal enclosure. Extensive industrial and safety certifications (including ATEX, IECEx, and DNV) ensure suitability for demanding automation environments.
