General
Power consumption	200 mA @ 12 bis 45 VDC

The IMC-101-M-ST from Moxa is an industrial media converter that enables the conversion of 10/100BaseT(X) copper Ethernet signals into 100BaseFX fiber optic transmission via a multi-mode ST connector. It is designed for use in demanding industrial environments where high mechanical robustness, EMI protection, and temperature resistance are required. The compact design and DIN rail mounting facilitate integration into existing industrial network infrastructures.

Applications
This converter is suitable for industrial applications requiring reliable data transmission over long distances, such as in manufacturing automation, power supply, or ship and machine building. Certification for hazardous areas (ATEX Zone 2, UL/cUL Class I Division 2 Groups A/B/C/D) makes it suitable for use in locations with increased safety requirements. Ship certification according to DNV extends the application range to marine applications.

Functions and Equipment in Detail
The IMC-101-M-ST features an RJ45 port for copper Ethernet connection and an ST port for fiber optic connection in multi-mode format. The integrated magnetic isolation with 1.5 kV protects network components from voltage surges and enables galvanic isolation between network segments. Power supply is via a terminal block with an input voltage of 12 to 45 VDC, and the converter supports overcurrent protection. Power consumption is 200 mA during operation.

Technology Explained Simply
The conversion from copper to fiber optic transmission is performed by the integrated media converter, which converts electrical signals into optical signals and vice versa. The use of multi-mode fiber optic via the ST connector enables transmission over medium to long distances with high bandwidth. The integrated galvanic isolation protects the network from electrical interference and potential differences, which is particularly important in industrial environments.

Compatibility and Accessories
The converter is compatible with standard Ethernet networks in the 10/100BaseT(X) range and supports fiber optic transmission according to the 100BaseFX standard. Certifications according to EN 55032/24, CISPR 32, and FCC Part 15B Class A ensure electromagnetic compatibility. Safety standards EN 60950-1 and UL 60950-1, as well as environmental tests according to IEC 60068-2-1/-2/-3, ensure reliability under various conditions.

Mounting and Installation
Mounting is done on a DIN rail, enabling quick and secure installation in enclosures. Power supply via terminal block is simple and requires no special tools. The compact dimensions of 53.6 x 135 x 105 mm and weight of 630 g allow flexible placement in the enclosure.

Operational Advantages
The operating temperature range of -40 to 75 °C allows use in extreme environments, such as outdoor installations or regions with strong temperature fluctuations. Humidity of 5 to 95 % (non-condensing) expands the range of applications. The high MTBF of 401,000 hours (according to MIL-HDBK-217F) demonstrates the high reliability of the device. The 5-year warranty underscores the quality and longevity of the product.

Protection Rating and Environmental Conditions
The housing is made of metal and provides an IP30 protection rating, protecting against solid foreign objects larger than 2.5 mm. The operating temperature of -40 to 75 °C and storage temperature of -40 to 85 °C allow use in harsh environments. Environmental tests according to IEC 60068-2-1/-2/-3 and vibration tests according to IEC 60068-2-6 ensure functionality under mechanical stress.

Certifications and Standards
The IMC-101-M-ST meets the requirements of the EMC Directive (EN 55032/24), EMI standards (CISPR 32, FCC Part 15B Class A), and EMS tests (ESD, RS, EFT, Surge, CS, PFMF, voltage dips). Safety standards EN 60950-1 and UL 60950-1, as well as certifications for hazardous areas (ATEX Zone 2, UL/cUL Class I Division 2) and ship certification (DNV), confirm suitability for critical applications.

Operational Safety and Reliability
The integrated galvanic isolation with 1.5 kV protects the network from interference and potential differences. The high MTBF of 401,000 hours and the 5-year warranty emphasize the reliability of the device. Certifications for hazardous areas and ship certification extend the application range to safety-critical environments.

Mounting and Maintenance
Mounting on the DIN rail is simple and requires no special tools. Power supply via terminal block is robust and easy to wire. The compact design and low weight facilitate placement in the enclosure. Maintenance is performed by visual inspection of status indicators and, if necessary, replacing the device in case of failure.
