The IMC-101-M-SC from Moxa is an industrial media converter from the IMC-101 series, converting Fast-Ethernet copper connections (10/100BaseT(X)) into optical 100BaseFX signals over multi-mode fiber optic cable with SC connector. It is used to connect Ethernet networks over longer distances, particularly in environments with electromagnetic interference, where stable and interference-free data transmission is required. The conversion is bidirectional, enabling the connection between copper and fiber optic segments in the network.

Applications
This converter is designed for industrial applications, particularly in automation technology and control systems, where high operational reliability and safety are required. It is suitable for locations with electromagnetic interference (EMI), such as production halls, factories, or facilities with powerful electrical machinery. The robust construction and approvals for hazardous areas (ATEX Zone 2, UL/cUL Class I Div. 2) extend its application range to explosive environments as well as marine environments (DNV approval).

Functions and Features in Detail
The IMC-101-M-SC features an RJ45 port for copper connection (10/100BaseT(X)) and an SC connector for fiber optic (100BaseFX, multi-mode). The integrated magnetic isolation with 1.5 kV protects connected devices from voltage surges and electrical disturbances. Power supply is via a terminal block with an input voltage of 12 to 45 VDC, with a current consumption of 200 mA. An integrated overcurrent protection provides additional safety.

Technology Explained Simply
The conversion of electrical Ethernet signals (copper) into optical signals (fiber optic) is performed by an integrated transceiver. Fiber optic transmission allows for greater reach and immunity to electromagnetic interference compared to copper cables. The multi-mode fiber optic cable is suitable for short to medium distances, with the exact range depending on the fiber quality and mode. The SC connector is a standardized, mechanically stable connection suitable for industrial applications.

Compatibility and Accessories
The converter is compatible with standard 10/100BaseT(X) Ethernet networks and 100BaseFX multi-mode fiber optic cables. It can be integrated into existing networks to connect copper and fiber optic segments. The use of fiber optic cables with SC connectors is required to utilize the optical interface. The approvals for hazardous areas (ATEX, UL/cUL) allow use in special environments, with the exact approval varying by region and application.

Mounting and Installation
The IMC-101-M-SC is mounted on a DIN rail, enabling quick and secure installation in enclosures. The metal housing provides mechanical protection and heat dissipation. The protection rating IP30 protects against solid foreign objects with a diameter of at least 2.5 mm and against splashing water, but not against direct water jets or immersion. Mounting requires no additional tools, with power supply connected via the terminal block.

Operational Advantages
The operating temperature range of 0 to 60 °C allows use in environments with moderate to high temperatures, such as industrial halls. The MTBF of 401,000 hours (according to MIL-HDBK-217F) indicates high reliability. Certifications according to EN 55032/24, CISPR 32, FCC Part 15B Class A and additional EMS tests (ESD, RS, EFT, Surge, CS, PFMF) ensure high immunity to electromagnetic interference. Safety approvals according to EN 60950-1 and UL 60950-1 ensure safe operation under industrial conditions.

Certifications and Standards
The converter meets the requirements of the EMC Directive (EN 55032/24), is approved for use in hazardous areas (ATEX Zone 2, UL/cUL Class I Div. 2), and has marine approval (DNV). Environmental tests according to IEC 60068-2-1/2/3 (climate, humidity, temperature) and vibration testing according to IEC 60068-2-6 ensure functionality under real operating conditions. The warranty is 5 years; further details are available on the manufacturer’s website.

Protection Rating and Environmental Conditions
The IP30 protection rating protects against solid foreign objects larger than 2.5 mm and against splashing water, but not against direct water jets. The operating temperature is between 0 and 60 °C, and the storage temperature is between -40 and 85 °C. Humidity is 5 to 95 %, non-condensing. These conditions are typical for industrial indoor environments and enclosures.

Dimensions and Weight
The device measures 53.6 mm (width) × 135 mm (height) × 105 mm (depth) and weighs 630 g. The compact design saves space in enclosures. DIN rail mounting is standardized and allows for quick installation.
