LevelOne RJ45 to ST Fast Ethernet Industrial Media Converter, Multi-Mode Fiber, 2km, -40°C to 75°C

LevelOne IEC-4002 is a compact industrial Fast Ethernet media converter that converts 10/100Base-TX copper signals to 100Base-FX fiber. Housed in a rugged aluminium case for effective heat dissipation, the unit is designed for DIN-rail or wall/panel mounting and provides visible status LEDs for straightforward monitoring of port link activity. The converter supports Link Fault Pass Through to notify remote equipment when link status changes and can operate as a pure converter or in switch mode.

Advantages

The aluminium mini-size enclosure ensures robust mechanical protection and improved thermal performance in industrial environments. Wide input power range with polarity protection allows flexible installation using AC or DC sources. Built-in surge and ESD protection, high immunity to noise and interference, and support for Link Fault Pass Through increase reliability for remote and harsh installations. Visible status LEDs simplify on-site diagnostics.

How to use

Mount the IEC-4002 on a DIN-rail or attach it to a wall or panel using appropriate fasteners. Connect the 10/100Base-TX copper cable to the RJ45 port and the 100Base-FX fiber cable to the fiber port, ensuring correct fiber connector type and cleanliness. Provide power using an appropriate AC (18–36VAC) or DC (12–60VDC) source, observing polarity protection. Monitor the front panel LEDs to verify link status and activity; enable or configure LFP behavior and mode (converter or switch) according to system requirements.

Recommendations

For reliable fiber links, use clean, properly matched fiber connectors and follow standard grounding and surge protection practices in industrial environments. Verify power source rating and wiring before powering the device.
