The Moxa ICF-1150 is an industrial media converter that connects serial interfaces in the RS-232/422/485 standard with fiber optic communication. It serves as a bridge between classic serial devices and modern fiber optic networks, enabling data transmission over long distances without impairing signal quality. The device is specifically designed for use in harsh industrial environments where high mechanical stress, extreme temperatures, and electromagnetic interference are common. The converter features an ST connector for multimode fibers, enabling reliable, galvanically isolated data transmission.

Applications

The ICF-1150 is suitable for applications in industrial automation, such as manufacturing control, power supply, transportation infrastructure, or process automation. It is used when serial devices, for example sensors, controls, or measuring instruments, need to be connected to a network over long distances without compromising signal integrity. The certification for hazardous areas (ATEX Zone 2, UL/cUL Class I Div. 2) extends its application range to environments with increased explosion risk, such as petrochemical or mining industries.

Functions and Equipment in Detail

The converter features two serial ports supporting the standards RS-232, RS-422, and RS-485 (in 2- and 4-wire technology). The baud rate can be set within a range of 50 bps to 921.6 kbps, including non-standard values. Data direction control is handled automatically via the ADDC function (Automatic Data Direction Control), simplifying the configuration of RS-485 networks. Galvanic isolation of 2 kV protects connected devices from voltage surges and potential differences. The RS-485 resistors can be individually configured, with various terminator and pull resistors (e.g. 120 Ω, 120 kΩ, 150 kΩ) available to adapt signal transmission to the respective topology.

Technology Explained Simply

The serial interface is connected via a 5-pin terminal block, with signal assignment varying according to the standard (RS-232, RS-422, RS-485). The fiber optic side uses an ST connector for multimode fibers, enabling high bandwidth and low attenuation. Power supply is provided via a terminal block with an input voltage of 12 to 48 VDC, with a maximum current draw of 300 mA. Integrated protection functions such as reverse polarity and overcurrent protection enhance operational safety. The robust metal housing provides mechanical protection, and the IP30 protection rating safeguards against finger contact and solid foreign objects, although not against water or dust.

Compatibility and Accessories

The ICF-1150 is compatible with a wide range of serial devices supporting the mentioned standards. The use of multimode fibers allows flexible integration into existing fiber optic infrastructures. Certifications according to EN 55032/35, CISPR 32, FCC Part 15B Class A, and IEC 61000-4-2 to -4-8 ensure high electromagnetic compatibility (EMC) performance, which is crucial for reliability in industrial environments. Explosion protection certifications (ATEX Zone 2, UL/cUL Class I Div. 2) allow use in hazardous areas.

Mounting and Installation

The device is designed for DIN rail mounting, enabling easy integration into existing enclosures. Dimensions are 30.3 × 70 × 115 mm, and weight is 330 g. Installation involves connecting the serial interface via the terminal block and the fiber optic connection via the ST connector. Power supply is also connected via the terminal block. Operating temperature ranges from -40 to 85 °C, enabling use in extreme environments. Humidity of 5 to 95 % (non-condensing) is also typical for industrial applications.

Operational Advantages

The ICF-1150 offers high operational reliability through galvanic isolation, integrated protection functions, and a robust design. Automatic data direction control (ADDC) reduces configuration effort for RS-485 networks. Support for non-standard baud rates extends compatibility with specialized devices. Certifications for hazardous areas and EMC robustness increase reliability in critical applications. The MTBF (Mean Time Between Failures) is 792,085 hours according to Telcordia standard, indicating high service life and low failure probability. The 5-year warranty underscores the quality and reliability of the device.
