General
Magnetic isolation	1,5 kV

The IMC-101-M-SC-T is an industrial media converter from Moxa, developed for use in demanding environments of industrial networking. It converts 10/100BaseT(X) Ethernet signals via an RJ45 port into 100BaseFX fiber data, transmitted through a multi-mode SC connector. This conversion enables the connection of copper and fiber networks, increasing the transmission range and immunity to interference. The device is specifically designed for use in factory automation, power distribution, the transport sector, and other areas where reliable communication under harsh operating conditions is required.

Applications

The IMC-101-M-SC-T is designed for industrial applications requiring high electromagnetic compatibility (EMC) resistance and environmental durability. It is suitable, for example, for networking machines in production facilities, for transmitting control and measurement data in power supply networks, or for communication solutions in vehicles and rail vehicles. Its robust construction and extended operating temperature range of -40 to 75 °C also make it suitable for outdoor or harsh environments where temperature fluctuations and mechanical stress occur.

Functions and Equipment in Detail

The device features an integrated magnetic isolator with a protection voltage of 1.5 kV, which electrically isolates network signals and prevents interference and voltage spikes in the network. This increases the safety and reliability of data transmission. The multi-mode SC connector allows connection to standard multi-mode fiber optic cables, commonly used in many industrial installations. The RJ45 port supports common Ethernet protocols 10/100BaseT(X), enabling easy integration into existing copper networks.

Technology Explained Simply

The media converter acts as a bridge between copper and fiber optic networks. It receives Ethernet data via the RJ45 cable, converts them into optical signals, and transmits them over the fiber optic cable. The conversion occurs without data loss and at high speed, as signals are transmitted according to the 100BaseFX standard. The integrated magnetic isolation protects the device and connected equipment from electrical disturbances caused by inductive or capacitive coupling. Power supply is via a terminal block with a voltage of 12 to 45 VDC, enabling flexible integration into existing power supply systems.

Compatibility and Accessories

The IMC-101-M-SC-T is compatible with standard multi-mode fiber optic cables with SC connectors. The use of cables with other connectors or modes (e.g., single-mode) is not intended and not supported. Power supply is via a terminal block, allowing connection to industrial power supplies. The devices are designed for use in environments with high electromagnetic interference and comply with relevant standards such as EN 55032/24 and CISPR 32.

Mounting and Installation

Mounting is done via a DIN rail, enabling quick and secure installation in enclosures. The robust metal housing with a protection rating of IP30 protects the device from mechanical impacts and limited dust and splash water ingress. Dimensions are 53.6 x 135 x 105 mm, allowing the device to fit in standardized enclosures. Installation requires no special tools, as mounting is done via the DIN rail and connections are made via terminal blocks.

Operational Advantages

The IMC-101-M-SC-T offers high operational reliability due to its robust construction and integrated magnetic isolation. The wide operating voltage range of 12 to 45 VDC allows flexible connection to various power supply systems. The long service life with an MTBF of 401,000 hours (according to MIL-HDBK-217F) and the 5-year warranty underline the reliability of the device. Certifications for hazardous areas (ATEX Zone 2, UL/cUL Class I Division 2) extend the application range to explosive environments. The marine certification (DNV) also makes the device suitable for use on ships.
