Moxa ICF-1150I-S-SC-T content_copy

The ICF-1150I-S-SC-T from Moxa is an industrial media converter that connects serial interfaces (RS-232/422/485) with a fiber optic network. It enables secure and reliable data transmission between serial devices and fiber optic cables in industrial environments, particularly where high electromagnetic immunity and extreme operating conditions prevail. The device is designed for use in enclosures and allows the integration of legacy devices into modern fiber optic networks without requiring additional hardware or software modifications.

Applications
This converter is suitable for industrial applications where serial devices such as sensors, controls, measuring instruments, or machines must be connected to a network via fiber optic cables. It is used in manufacturing, energy supply, transportation, and other sectors where high mechanical and electrical stresses as well as extreme temperatures occur. The certification for hazardous areas (UL/cUL Class I Div. 2, ATEX Zone 2) extends its application range to explosive environments.

Functions and Features in Detail
The ICF-1150I-S-SC-T features two serial ports supporting RS-232, RS-422, and RS-485 standards (in 2- and 4-wire technology). The baud rate can be set between 50 bps and 921.6 kbps, including non-standard transmission rates. Serial connections are made via a 5-pin terminal block. For fiber optic communication, an SC connector for multimode fiber is provided. Galvanic isolation of 2 kV protects against interference and voltage spikes, which is especially important in electrically harsh environments.

Technology Explained Simply
The automatic data direction control (ADDC) for RS-485 enables bidirectional communication without additional control lines. Configurable pull-up and termination resistors (150 kΩ to 485 Ω in 10 steps, as well as 120 Ω and 120 kΩ) allow adaptation to existing network topologies and prevent signal reflections. Signal assignment is clearly defined: RS-232 (TxD, RxD, GND), RS-422 (Tx+, Tx-, Rx+, Rx-, GND), RS-485 (4-wire: Tx+, Tx-, Rx+, Rx-, GND; 2-wire: Data+, Data-, GND). Power supply is via a terminal block with 12 to 48 VDC, with a maximum current consumption of 300 mA. Overcurrent and reverse polarity protection safeguard the device against misuse.

Compatibility and Accessories
The converter is designed for use with multimode fiber optic cables with SC connectors. It is compatible with serial devices supporting the mentioned standards. Certifications according to EN 55032/35, CISPR 32, FCC Part 15B Class A, as well as IEC 61000-4-2 to -4-8 ensure high EMC and EMS compatibility. Safety certification UL 61000-2-201 and environmental tests according to IEC 60068-2-1, -2, -3, as well as vibration tests according to IEC 60068-2-6 confirm its robustness. Certification for UL/cUL Class I Div. 2 and ATEX Zone 2 allows use in hazardous areas.

Mounting and Installation
The device is delivered in a robust metal housing designed for DIN rail mounting. The IP rating IP30 protects against contact with foreign objects larger than 2.5 mm and against splashing water, but not against direct water jets or immersion. Dimensions are 30.3 × 70 × 115 mm, weight 330 g. Mounting is directly into the enclosure, with the DIN rail ensuring secure fastening.

Operational Advantages
The high operating temperature range of -40 to 85 °C enables use in extreme environments, such as outdoor installations or industrial halls with high temperatures. The MTBF (Mean Time Between Failures) is 792,085 hours according to Telcordia/Bellcore, indicating high reliability. The 5-year warranty underscores the quality of the device. The combination of galvanic isolation, EMC protection, and robust housing ensures long service life and low maintenance costs in industrial operation.
