The Moxa ICF-1150I-M-SC-T-IEX is an industrial-grade serial-to-multimode fiber converter that supports RS-232, RS-422, and RS-485 interfaces. It offers a rugged design with a wide operating temperature range of -40 to 85°C and is certified for use in hazardous environments (ATEX Zone 2, IECEx), making it ideal for mission-critical deployments in oil and gas, transportation, and heavy industry.

This model features 2 kV isolation to protect against ground loops and surges, and supports automatic RS-485 data direction control (ADDC), easing integration. A wide selection of termination and pull-up/down resistor values adds versatility for custom RS-485 topologies.
