More Information

Overview Manuals Specifications Application Scenarios Communication Compatibility

Features:

  • Provides a point-to-point fiber optic communication link between Modbus Plus network sections.
  • Uses multimode fiber to extend communication paths while reducing exposure of the optical section to electromagnetic interference.
  • Combines an electrical Modbus Plus interface with a fiber optic transceiver for integration into Modicon Premium and Modicon Quantum automation networks.
Schneider Electric 490NRP25300 provides a practical communication link for industrial control systems where Modbus Plus devices are distributed across separate production areas, buildings, or process sections. Rather than keeping the entire network on electrical cable, the repeater introduces a fiber optic section between two Modbus Plus connections. The arrangement supports network expansion while maintaining communication between connected PLC equipment. Applications can include large manufacturing lines, electrical monitoring systems, transportation infrastructure, water treatment facilities, and process plants. Fiber transmission can be especially useful where conventional network cabling would pass through electrically demanding industrial environments.

A key application value of 490NRP25300 comes from the point-to-point network structure. One electrical Modbus Plus interface communicates through one fiber optic transceiver, creating a dedicated optical link between two network sections. The architecture allows separated network areas to remain part of the same industrial communication system without requiring continuous electrical cabling across the entire route. Optical path planning should consider cable attenuation, connector losses, splices, and available optical power margin. Schneider Electric documentation recommends graded-index multimode glass fiber for the repeater family.

For maintenance personnel, Schneider Electric 490NRP25300 also provides status indication for power, Modbus Plus activity, and the fiber port. Such indicators can assist during commissioning and fault isolation when communication is interrupted between network sections. Schneider Electric troubleshooting guidance uses two 490NRP25300 repeaters in a point-to-point configuration and identifies LED behavior as part of network diagnosis. Combined with the repeater's fiber optic communication function, the arrangement supports dependable operation in distributed automation systems where communication continuity is important to overall process availability.

The 490NRP25300 Schneider Electric Fiber Optic Repeater may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Description
Schneider Electric 490NRP25300 is a fiber optic repeater for Modbus Plus networks within Modicon Premium and Modicon Quantum automation platforms. The unit provides a point-to-point optical connection between two Modbus Plus network sections, combining an electrical Modbus Plus interface with a fiber optic transceiver. Converting the communication path to optical fiber helps extend network connections beyond conventional electrical cable installations and provides a practical method for linking separated control areas.

In industrial plants, 490NRP25300 can be used where communication paths pass through areas affected by electromagnetic or radio-frequency interference. Fiber optic transmission does not depend on electrical signal conduction along the communication medium, making the repeater suitable for distributed PLC networks in power monitoring, heavy industry, metallurgy, transportation systems, water treatment, and process control installations. The repeater regenerates the communication signal between network sections so that attenuation along the transmission path can be managed more effectively.

Schneider Electric 490NRP25300 operates with multimode fiber rather than single-mode fiber. Schneider Electric specifically identifies multimode fiber for 490NRP25300, while the repeater guide recommends 62.5/125 µm graded-index multimode glass fiber for general applications. The documented optical interface uses ST-type connectors and an 820 nm optical wavelength, with point-to-point distances dependent on fiber size, attenuation, connectors, splices, and the total optical power-loss budget. The documented operating temperature range is 0°C to 60°C, while storage temperature extends from -40°C to +85°C with 10% to 95% non-condensing humidity.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How does Schneider Electric 490NRP25300 help extend communication distance?
The repeater receives and retransmits communication through a fiber optic point-to-point link. Actual allowable distance depends on fiber attenuation, connectors, splices, and the total optical loss budget rather than a single universal cable-length value.
Can 490NRP25300 operate with single-mode fiber?
No. Schneider Electric specifies multimode fiber for 490NRP25300. The repeater documentation recommends graded-index multimode glass fiber, particularly 62.5/125 µm fiber for general installations.
What optical wavelength does 490NRP25300 use?
The fiber optic repeater specification identifies an optical wavelength of 820 nm. Fiber selection and attenuation calculations should therefore be based on the optical characteristics specified for the repeater and installed cable.
Does Schneider Electric 490NRP25300 support point-to-point communication?
Yes. Point-to-point operation is the defined Modbus Plus application for 490NRP25300. The repeater contains one fiber optic transceiver and one electrical Modbus Plus interface for connecting two network sections.
