Moxa IMC-101-S-SC content_copy

The IMC-101-S-SC from Moxa is an industrial media converter that converts Ethernet signals in the format 10/100BaseT(X) via an RJ45 port into optical 100BaseFX signals via an SC multi-mode fibre connection. The device is designed for use in harsh industrial environments where high electromagnetic compatibility, mechanical robustness, and reliability are required. It enables the connection of wired Ethernet networks with fibre optic infrastructures, allowing secure and stable data transmission over long distances and in electromagnetically noisy environments.

Applications
This converter is particularly suitable for industrial automation applications, such as in manufacturing, energy supply, transportation, or process automation. The certifications for use in hazardous areas (ATEX Zone 2, UL/cUL Class I Division 2 Groups A/B/C/D) extend its application range to hazardous installations. The maritime certification (DNV) also makes it suitable for use on ships or in marine environments. The operating temperature range of 0 to 60 °C allows use in indoor environments as well as in protected outdoor areas.

Functions and Features in Detail
The device features an RJ45 port for connecting to Ethernet networks and an SC multi-mode fibre connection for optical data transmission. The integrated magnetic isolation with 1.5 kV protects connected devices 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, with a current consumption of 200 mA. An integrated overcurrent protection provides additional safety.

Technology Explained Simply
The conversion of electrical Ethernet signals into optical signals is performed by an integrated transceiver. The fibre optic connection via SC connectors enables high bandwidth and low signal loss over long distances. Multi-mode fibre is suitable for short to medium distances in industrial applications. The galvanic isolation at 1.5 kV protects against electrical interference and potential differences, which are common in industrial networks. EMC protection measures, such as ESD protection (6 kV contact, 8 kV air), EFT (2 kV power, 1 kV signal), and surge protection (2 kV power, 1 kV signal), ensure stable operation even in the presence of electromagnetic interference.

Compatibility and Accessories
The converter is compatible with standard Ethernet networks and can be integrated into existing automation systems. The certifications for hazardous areas allow use in installations subject to special safety requirements. The maritime certification (DNV) enables use in marine environments.

Mounting and Installation
The device is mounted on a DIN rail, enabling quick and secure installation in enclosures or control cabinets. The robust metal housing provides mechanical protection, and the protection rating IP30 protects against contact with moving parts and against larger solid objects. Dimensions are 53.6 x 135 x 105 mm, and the weight is 630 g.

Operational Advantages
The high EMC immunity, galvanic isolation, and certifications for hazardous areas increase the reliability and safety of operation. The long service life (MTBF 401,000 hours according to MIL-HDBK-217F) and the 5-year warranty underline the quality and durability of the device. The compact design and DIN rail mounting facilitate integration into existing systems. The operating temperature range of 0 to 60 °C allows use in a wide range of industrial environments.
