The Moxa ICF-1150I-M-SC is an industrial-grade serial-to-fiber converter designed to convert RS-232, RS-422, and RS-485 signals into 100BaseFX over multi-mode fiber with an SC connector. With built-in 2 kV isolation, it ensures safe data transmission in electrically noisy environments and offers reliable protection against surges and ground loops.

Its compact metal housing, wide DC input range (12–48 VDC), and DIN-rail mounting make it suitable for control cabinets and field deployments. The ADDC (automatic data direction control) functionality simplifies RS-485 network integration. The unit also offers flexible pull resistor and termination options for versatile serial configurations.
