The ICF-1150I-S-SC-IEX from Moxa is an industrial converter that converts serial interfaces of the RS-232, RS-422 and RS-485 standards into multimode fibre optic with SC connector. The device is designed for use in hazardous explosive environments, secured by certifications UL/cUL Class I Div. 2, ATEX Zone 2 and IECEx. The operating temperature range of -40 to 85 °C enables use in extreme industrial conditions, for example in process industry, energy sector or manufacturing. The galvanic isolation of 2 kV protects connected devices from voltage surges and potential differences, increasing the reliability and safety of communication.

Applications include all scenarios requiring serial data transmission over long distances without signal interference from electrical noise. Typical use cases are connecting control devices, sensors, frequency converters or industrial PCs via fibre optic cables, especially in environments with high electromagnetic interference or where galvanic isolation is required.

Functions and features in detail include two serial ports, which can be configured as RS-232, RS-422 or RS-485 (2- or 4-wire) depending on requirements. The baud rate can be set between 50 bps and 921.6 kbps, including support for non-standard transmission rates. The automatic data direction control (ADDC) for RS-485 enables easy integration into existing networks without requiring additional control lines. For RS-485 configuration, various pull-up/pull-down resistors (e.g. 150 kΩ, 10 kΩ, 4.7 kΩ, 3.3 kΩ, 1 kΩ, 909 Ω, 822 Ω, 770 Ω, 500 Ω, 485 Ω) and terminator options (N/A, 120 Ω, 120 kΩ) are available to ensure signal integrity.

Technology explained simply shows that the converter features a 5-pin terminal block for serial connections and an SC connector for the multimode fibre cable. Power supply is via a terminal block with an input voltage of 12 to 48 VDC, with a maximum current consumption of 300 mA. The converter includes overcurrent protection and reverse polarity protection to prevent damage from incorrect connection conditions. The housing is made of metal and offers IP30 protection, safeguarding against mechanical impacts and limited protection against solid foreign objects. Mounting is done on a DIN rail, enabling flexible installation in enclosures.

Compatibility and accessories refers to use with multimode fibre optic cables with SC connector. The converters are designed for industrial networks requiring high levels of electromagnetic compatibility, reliability and safety. Certifications according to EN 55032/35, CISPR 32, FCC Part 15B Class A as well as IEC 61000-4-2 to -4-8 guarantee high EMC and EMS compliance. Safety certification UL 61010-2-201 and environmental tests according to IEC 60068-2-1, -2, -3 as well as vibration tests according to IEC 60068-2-6 highlight the robustness of the device.

Mounting and installation is done via DIN rail, allowing integration into existing enclosures. Connections are made via terminal blocks, ensuring a secure and reliable connection. The operating temperature range of -40 to 85 °C requires no additional cooling or heating measures in most industrial environments.

Operational advantages include high reliability, galvanic isolation, support for various serial standards and flexible configuration options. The MTBF is 792,085 hours according to Telcordia/Bellcore, indicating high service life and low failure probability. The 5-year warranty underscores the quality and durability of the product. The device is designed for use in critical industrial applications where stable and secure communication is essential.
