The ICF-1150I-M-ST-T is an industrial-grade serial-to-fiber converter supporting RS-232/422/485 and multimode fiber via ST connector. Designed for extreme conditions, it operates in a wide temperature range of -40 to 85°C and features 2 kV galvanic isolation for reliable signal protection and system integrity.

The converter includes automatic data direction control (ADDC) for RS-485 communication and configurable terminator and pull-up/pull-down resistors, making it flexible for various deployment needs. Power is supplied via 12 to 48 VDC input and installation is DIN-rail friendly.
