The ICF-1180I-S-ST from Moxa is an industrial media converter specifically designed for connecting PROFIBUS-DP networks with fiber optic cables. It enables secure and reliable data transmission over long distances, protecting against electromagnetic interference and ground potential differences through integrated isolation. The device is designed for use in demanding industrial environments where high immunity to interference and mechanical robustness are required.

Applications
This converter is suitable for industrial automation systems where PROFIBUS-DP networks need to be extended over long distances or connected to existing fiber optic infrastructures. Typical applications include production facilities, power supply, transportation technology, and marine installations. Support for hazardous areas (ATEX, IECEx, Class I Division 2) extends its use into explosive environments.

Functions and Features in Detail
The ICF-1180I-S-ST features a PROFIBUS-DP interface with a DB9 female connector, supporting baud rates from 9600 bps to 12 Mbps. Available signals include PROFIBUS D+, D-, RTS, Signal GND, and 5V. The integrated 2-kV isolation protects against electrical interference and potential differences. On the optical side, a singlemode ST connector is integrated, enabling stable fiber optic communication. Power supply is provided via a terminal block with an input voltage range of 12 to 48 VDC, with two power inputs available. Overcurrent protection is also implemented.

Technology Explained Simply
The use of singlemode fiber optic enables high data transmission rates over long distances with minimal signal attenuation. The ST connector is a standardized fiber optic interface commonly used in industrial applications. The integrated 2 kV isolation ensures that electrical disturbances caused by differing ground potentials or inductive coupling do not enter the network. The wide input voltage range of 12 to 48 VDC increases installation flexibility, allowing the device to be connected to various industrial power supplies.

Compatibility and Accessories
The converter is designed for use with PROFIBUS-DP networks and supports the standard protocols of this bus type. The fiber optic side is designed for singlemode cables, with the ST connector providing the physical connection. Certifications according to ATEX, IECEx, and Class I Division 2 allow use in hazardous areas. Compliance with EMC standards such as EN 55032/35, CISPR 32, and FCC Part 15B Class A ensures low electromagnetic emissions and immunity to interference.

Mounting and Installation
The device is housed in a robust metal housing with protection rating IP30 and can be mounted either on a DIN rail (optional) or on a wall. Dimensions are 30.3 × 115 × 70 mm, and weight is 180 g. Mounting requires no additional tools, with DIN rail mounting being optional. Operating temperature ranges from 0 to 60 °C, and relative humidity is 5 to 95 % (non-condensing).

Operational Advantages
The ICF-1180I-S-ST offers high reliability with an MTBF of 1,722,769 hours (Telcordia, GB). The integrated isolation and robust construction ensure long service life and low maintenance. Support for two power inputs increases availability, as redundant power connections are possible. Compliance with international safety and environmental standards (IEC 60950-1, UL 508, IEC 60068-2-1/-2/-3, IEC 60068-2-6, DNV) ensures safe operation in various environments. The 5-year manufacturer’s warranty underscores the quality of the device.
