The IMC-101-M-SC-T-IEX is an industrial media converter from Moxa's IMC-101 series, converting 10/100BaseT(X) copper connections to 100BaseFX fiber optic. It is specifically designed for use in hazardous environments, as it meets the certifications IECEx, ATEX Zone 2, and UL/cUL Class I Division 2 Groups A/B/C/D. These approvals make it suitable for applications in the oil and gas industry, mining, or other areas with explosion risks. The device features a multi-mode SC connector for fiber optic communication and an RJ45 port for copper connection, serving as a bridge between different network media.

Applications

The IMC-101-M-SC-T-IEX is used in industrial networks where reliable data transmission over long distances is required, for example in production facilities, power supply networks, or rail transport. The fiber optic transmission offers advantages such as high bandwidth, low signal loss, and immunity to electromagnetic interference. The certifications for hazardous areas extend its application range to installations where explosion hazards exist, without requiring additional protective measures.

Functions and Features in Detail

The device includes an integrated magnetic isolation filter of 1.5 kV, which electrically isolates network signals and prevents disturbances or voltage surges in the network. The power supply is via a terminal block with an input voltage of 12 to 45 VDC, with a current consumption of 200 mA. An overcurrent protection is also integrated to protect the device from damage due to excessive current draw. The DIN rail mounting allows for quick and secure installation in enclosures.

Technology Explained Simply

The media converter converts the electrical signals of an Ethernet copper cable (RJ45) into optical signals for a fiber optic cable (SC connector, multi-mode). This enables longer reach and higher immunity to interference compared to pure copper connections. The protection rating IP30 ensures protection against solid foreign objects (minimum 2.5 mm) and is suitable for use in enclosed enclosures. The metal housing provides additional protection against mechanical impacts and improves EMI shielding. The operating temperature of -40 to 75 °C makes the device suitable for extreme environmental conditions, such as those found in outdoor installations or regions with extreme climates.

Compatibility and Accessories

The IMC-101-M-SC-T-IEX is compatible with standard Ethernet networks and can be integrated into existing infrastructures. The use of multi-mode fiber optic cables with SC connectors is required. The certifications ATEX, IECEx, and UL/cUL Class I Division 2 allow use in explosive environments. The maritime certification DNV extends the application range to ships and offshore installations.

Mounting and Installation

Mounting is done via a DIN rail, enabling quick and secure fixation in standard enclosures. Power supply is via a terminal block connected directly to the supply voltage. Connections for copper and fiber optic cables are clearly marked and easily accessible. Installation requires no special tools or additional components.

Operational Advantages

The IMC-101-M-SC-T-IEX offers high reliability due to its robust construction and integrated isolation. The MTBF of 401,000 hours according to MIL-HDBK-217F indicates the high service life of the device. The 5-year warranty underscores its quality and durability. The combination of EMI protection, temperature resistance, and certifications for hazardous areas makes the device a reliable solution for demanding industrial applications.

Certifications and Standards

The device complies with EMI standards EN 55032/24, CISPR 32, and FCC Part 15B Class A. EMS tests include ESD (6 kV contact, 8 kV air), RS (10 V/m), EFT (2 kV power, 1 kV signal), Surge (2 kV power, 1 kV signal), CS (3 V/m), PFMF (IEC 61000-4-8), and voltage interruption (IEC 61000-4-11). Safety standards EN 60950-1 and UL 60950-1, as well as environmental tests according to IEC 60068-2-1/-2/-3 and vibration (IEC 60068-2-6), guarantee reliability under industrial conditions.
