Product Description

The 490NRP95400 (490-NRP-954-00) is a fiber optic Remote I/O (RIO) repeater for the Schneider Electric Modicon Quantum PLC platform. It extends the reach of the RIO network beyond standard coaxial cable limits, providing total electrical isolation and eliminating ground loops and EMI in industrial environments. This module supports long-distance, high-speed, deterministic communication between the CPU and remote I/O racks, making it ideal for distributed installations across multiple buildings or expansive plant floors.

Network Extension and Reliability

  • Extends RIO network distances beyond the 500-meter coaxial limit, up to several kilometers depending on fiber quality and layout.

  • Ideal for environments with high-voltage equipment or lightning-prone areas, preventing electrical surges from affecting communications.

  • Supports mixed topologies (point-to-point, star, ring) and can bridge coaxial and fiber optic segments seamlessly.

Technical FAQ

Can coaxial and fiber optic segments be mixed in the same RIO network?
Yes. The 490NRP95400 acts as a bridge, allowing coaxial from the CPU to the first repeater, then fiber optic to distant remote racks, where another repeater converts signals back for local I/O.

Does this module require software configuration in Unity Pro?
No. The module operates transparently at the physical layer, repeating RIO signals without complex logic programming. Drop addresses on remote adapters must still be set correctly.
