Features:
- Extends Modbus Plus communication up to 3000 meters per hop using 62.5/125 µm multimode fiber.
- Fiber optic transmission eliminates the effects of electromagnetic and radio-frequency interference commonly found in industrial facilities.
- Mounts directly into a Quantum baseplate and operates from the 5 VDC backplane power supply without additional external power.
The Schneider Electric 490NRP25400 provides an effective solution for extending Modbus Plus communication beyond the limitations of conventional copper cabling. By converting electrical signals into optical signals, the module enables stable data transmission across large industrial sites while maintaining the fixed 1 Mbps network communication rate. This makes it suitable for distributed automation systems where equipment is installed over long distances.
Industrial environments often contain heavy electrical equipment capable of generating significant electromagnetic interference. The 490NRP25400 uses multimode fiber optic communication to eliminate the influence of electrical noise, helping maintain reliable communication between PLCs and other Quantum control devices. Optical transmission also introduces electrical isolation, reducing the possibility of damage caused by lightning, ground loops, or electrical faults.
Designed for direct installation into a Quantum module baseplate, the Schneider Electric 490NRP25400 requires no separate power source because it operates from the 5 VDC Quantum backplane. The combination of a 9-pin copper interface, dual ST fiber optic connectors, and support for 3000-meter transmission distances makes the module a practical choice for expanding Modicon Quantum networks in manufacturing plants, processing facilities, and other demanding industrial applications.
The 490NRP25400 Schneider Electric Fiber Optic Repeater MBPL Line may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

- Fiber Optic Terminals: The panel integrates two sets of standard ST-type locking fiber optic connectors for independent signal transmission (TX) and reception (RX).
- Electrical Ports: The bottom is equipped with one standard Sub-D 9-pin female connector for connecting to a local Modbus Plus copper network.
- Topology Cascading: Supports point-to-point serial connections via fiber optic media, or the construction of highly flexible star branch topologies through multi-module combinations.
- Physical Media: The physical layer link strictly requires 62.5/125 micrometer (µm) multimode fiber to ensure minimal optical power loss.
- Long-Distance Interconnection Across Plants: Widely used in large-scale industrial sites such as metallurgy and water treatment plants, bridging distributed control master stations over distances of several kilometers.
- High-Voltage Interference Isolation: Deployed in environments with strong electromagnetic interference (EMI), such as those containing large frequency converters and high-voltage power distribution rooms, using fiber optics to achieve interference-free communication.
- Lightning Strike Ground Potential Isolation: In backbone networks susceptible to lightning strikes, such as outdoor pipeline transportation and long-distance conveyor belts, the electrical path between the control cabinets at both ends is severed to prevent equipment burnout.
- Partial Expansion of Existing Network Segments: Used for the maintenance and in-situ upgrade of existing Modbus Plus network facilities, extending the total length of copper cable communication without changing the original PLC architecture.
- Network Protocol: Natively optimized for 1 Mbps Modbus Plus (MBPL) industrial token bus networks at the hardware layer.
- Platform Compatibility: Adopts the modular form factor standard of the Quantum series, fully compatible and directly plugged into the 140XBP series master/slave backplane.
- Power Supply Compatibility: Requires no external power cables; securely obtains 5 VDC operating voltage directly from the system bus in the backplane slot.
- Replacement Transition: As the Quantum platform is phased out, the functionality of this fiber optic repeater hardware in new control systems will be replaced by dedicated gateways or optoelectronic conversion kits.
