The ICF-1150-M-SC-T from Moxa is an industrial media converter that integrates serial interfaces RS-232, RS-422, and RS-485 via multi-mode fiber optic cable with SC connector into an Ethernet network. It is designed for use in harsh industrial environments, particularly in areas such as automation, transportation, and energy, where high electromagnetic interference and extreme environmental conditions occur. The converter enables the connection of legacy devices to modern network infrastructures, with data transmission via fiber optic cable, ensuring high immunity to interference and long transmission distances.

Applications

The ICF-1150-M-SC-T is suitable for applications where serial devices such as sensors, controls, or measuring instruments need to be integrated into an Ethernet network. The use of fiber optic cables with SC connector enables reliable data transmission over distances of several kilometers, independent of electromagnetic interference. The operating temperature range of -40 to 85 °C makes it suitable for outdoor use, in climate control systems, in manufacturing, or in power generation. Certification to UL/cUL Class I Division 2 and ATEX Zone 2 allows use in hazardous explosive areas.

Features and Equipment in Detail

The converter features two serial ports that can be configured between the standards RS-232, RS-422, and RS-485 (in 2- and 4-wire technology). The baud rate can be set between 50 bps and 921.6 kbps, including support for non-standard transmission rates. Data direction control for RS-485 is handled automatically via ADDC technology, simplifying integration into existing serial systems. Additionally, various configurable pull-up/pull-down resistors and termination resistors (120 Ω, 120 kΩ) are available to ensure signal integrity across different network topologies.

Technology Explained Simply

The serial interfaces are connected via a 5-pin terminal block, while the fiber optic side is connected via an SC connector. Power supply is provided via a terminal block in the range of 12 to 48 VDC, with the converter featuring protection against overcurrent and reverse polarity. The maximum current consumption is 300 mA. The housing is made of metal and has an IP30 protection rating, offering protection against solid foreign objects and limited splashing water. Mounting is done on a DIN rail, enabling flexible installation in enclosures.

Compatibility and Accessories

The ICF-1150-M-SC-T is designed for use with multi-mode fiber optic cables connected via an SC connector. The serial interfaces support common protocols RS-232, RS-422, and RS-485, with signal assignments defined per mode (e.g., RS-485-4w: Tx+/-, Rx+/-, GND). Configuration of pull resistors and termination resistors allows adaptation to various network topologies. Certifications to EN 55032/35, CISPR 32, FCC Part 15B Class A, and IEC 61000-4-2 to -4-8 ensure high EMC and EMS compliance.

Mounting and Installation

Mounting is done on a DIN rail, enabling quick and secure installation in standard enclosures. Connections for serial interfaces and power supply are made via terminal blocks, ensuring a secure mechanical connection. The fiber optic side is connected via an SC connector, with the connection made using a multi-mode fiber optic cable. Installation requires no special tools, and configuration is done via physical settings on the device.

Advantages in Operation

The ICF-1150-M-SC-T offers high reliability due to its robust construction and support for extreme environmental conditions. The automatic data direction control (ADDC) for RS-485 reduces complexity when integrating into existing systems. Support for non-standard baud rates and flexible selection of pull resistors increases adaptability to different applications. Certification for hazardous explosive areas extends its application range in sensitive industrial environments. The MTBF is 792,085 hours according to Telcordia standard, indicating a high service life. The warranty is 5 years.
