The ICF-1150I-M-ST is an industrial-grade serial-to-fiber converter engineered for robust and interference-free communication in demanding environments. It supports RS-232, RS-422, and RS-485 interfaces, and uses a multimode fiber ST connector for extended transmission distances. With 2 kV galvanic isolation, it safeguards connected devices from electrical surges and disturbances.

Ideal for applications in automation, energy, transportation, and more, this converter operates reliably within a temperature range of 0 to 60°C.
