The Schneider Electric 490NRP25300 is a dedicated fiber optic repeater engineered to extend the reach of Modbus Plus networks within the Modicon Quantum and Premium automation ecosystems. By converting standard RS-485 copper signals into fiber optic transmissions, this module facilitates long-range communication while providing complete galvanic isolation. It is an essential component for industrial facilities where long cable runs, high electromagnetic interference (EMI), or ground potential differences threaten network reliability.

Features

  • Signal Conversion: Seamlessly bridges Modbus Plus copper media to fiber optic media.
  • Extended Range: Supports signal transmission over distances up to 3 km, depending on fiber quality.
  • Noise Immunity: Fiber optic isolation eliminates ground loops and protects against electrical noise in high-voltage environments.
  • Network Flexibility: Supports point-to-point and star network topologies.
  • Diagnostic Monitoring: Integrated LED indicators provide real-time status updates for power, copper link activity, and fiber signal detection.

FAQ

Does the 490NRP25300 support single-mode fiber?

No, this module is specifically designed for use with multimode fiber (62.5/125 um or 50/125 um) at an 820 nm wavelength.

Can this repeater be used in hazardous locations?

The module carries certifications including UL, CSA, CE, and FM Class I Div 2, making it suitable for many demanding industrial environments. Always verify specific site requirements against the device's documentation.

How is the module powered?

The unit requires an external 24 VDC power supply, typically sourced from the industrial control cabinet's power distribution system.
