The Moxa ICF-1180I-M-ST-T is an industrial media converter that transmits PROFIBUS-DP signals over a multimode fibre cable. It serves as a bridge between a PROFIBUS network and an optical fibre infrastructure, thereby increasing the communication range and noise immunity. The device is designed for use in industrial environments where high mechanical stress, extreme temperatures, and electromagnetic interference may occur.

Applications
This converter is intended for applications in industrial automation and control, particularly in production facilities, power supply networks, or machine building. It enables the extension of PROFIBUS-DP networks over long distances, with fibre cables offering higher immunity to electromagnetic interference compared to copper cables. The operating temperature range of -40 to 75 °C makes it suitable for outdoor use or demanding climatic environments, such as in conveyor technology or heavy industry.

Functions and Features in Detail
The ICF-1180I-M-ST-T features a serial PROFIBUS interface with a DB9 connector (female) and supports baud rates from 9600 bps to 12 Mbps. The integrated galvanic isolation of 2 kV protects the device and connected equipment from voltage surges and potential differences. Signals PROFIBUS D+, D-, RTS, Signal Common, and 5V are transmitted, ensuring compatibility with standard PROFIBUS end devices. The optical interface uses an ST connector for multimode fibre, representing a cost-effective and widely used solution for industrial fibre communication.

Technology Explained Simply
Fibre communication transmits data as light signals, which are not affected by electromagnetic fields. This increases the reliability of data transmission, especially in environments with strong interference sources such as motors, transformers, or switchgear. Multimode fibre allows for greater bandwidth than single-mode fibre, but is limited to shorter distances. The ST connector is a mechanically robust and easy-to-connect fibre cable system widely used in many industrial installations.

Compatibility and Accessories
The device is designed for PROFIBUS-DP networks and can be connected to standard PROFIBUS end devices and master systems. Power supply is provided via a terminal block, with two inputs available for redundant power supply. The input voltage ranges from 12 to 48 VDC, enabling flexible integration into existing power supply systems. The integrated overload protection function safeguards the device against current surges.

Mounting and Installation
The converter can be wall-mounted or mounted on a DIN rail using an optional mounting bracket. The metallic housing construction provides mechanical stability and protection against external influences. The IP30 protection rating safeguards against finger contact and solid foreign objects, but not against water or dust. Installation is performed by connecting the PROFIBUS cable to the DB9 connector and attaching the fibre cable to the ST connector. Power supply is provided via the terminal block.

Operational Advantages
Galvanic isolation and fibre communication enhance noise immunity and operational safety. The wide operating temperature range of -40 to 75 °C enables use in extreme environments. Redundant power supply via two inputs increases device availability. The high MTBF (1,722,769 hours) according to Telcordia and GB standards demonstrates the device’s high reliability. Certifications according to ATEX, IECEx, and DNV make it suitable for use in explosive environments or in marine applications. Compliance with EMC and safety standards such as IEC 60950-1 and UL 508 ensures safe operation in industrial facilities.
