The ICF-1150I-M-ST-T is an industrial-grade RS-232/422/485 to multi-mode fiber converter with an ST connector. It features 2 kV galvanic isolation, automatic data direction control (ADDC) for RS-485, and supports both standard and non-standard baudrates. Designed for extreme environments, it operates in a wide temperature range from -40 to 85°C.

Its rugged metal housing, DIN-rail mounting capability, and built-in protection features such as reverse polarity and overload protection make it a highly reliable solution for extending serial communication over fiber in industrial settings. Certifications for hazardous locations and strong EMC immunity further ensure dependable performance.
