Product Overview
Long cable runs in industrial plants weaken optical signals and corrupt data. The 140NRP95401C from Schneider Electric solves that problem. It is a coated fibre optic repeater built for the Modicon Quantum automation platform. The unit regenerates single mode optical traffic so control data keeps moving across large facilities. It dissipates 5 W and draws 750 mA of bus current. With two LC fibre optic ports and one coaxial connector, it fits practical network layouts without extra hardware.

Key Parameters That Matter
Power and Start-Up Behaviour
The repeater needs 750 mA of bus current and dissipates 5 W. Inrush current reaches 1.8 A at 5 V DC. Plan your power budget around these figures so the module starts cleanly alongside other Quantum components.
Optical Ports and Cabling
Two ports accept LC fibre optic connectors for single mode cable. A third port uses a coaxial connector. This mix lets you link fibre segments and legacy coaxial runs inside one repeater.
Status Signalling
Four green LEDs and three red LEDs report local status. Green indicates normal operation; red flags a fault. Technicians can read module health at the cabinet without a laptop.
Environmental Envelope
Ambient operating temperature spans 0 to 60°C in a non-condensing environment. Storage temperature spans -40 to 85°C. Humidity tolerance reaches 0 to 95% relative humidity without condensation, and operating altitude reaches 2,000 m above sea level.
Physical Build
The housing uses PC (polycarbonate) material. Net weight is 0.5 kg, so one person can handle installation.
Where It Fits in Service
Oil and gas plants often run control networks across kilometres of process area. Single mode fibre carries signals far, but distance and joints still cost optical power. The 140NRP95401C restores signal strength between segments, keeping Modicon Quantum I/O data intact.
Water treatment and pipeline stations face the same issue. A repeater placed between long fibre spans protects data integrity where cable replacement is impractical.

Integration Notes
This repeater belongs to the Modicon Quantum automation platform, so it integrates with existing Quantum racks and cabling. Wiring into plant networks may require an external gateway or connection module. Confirm cables and gateways with your supplier before ordering.
Selection Checklist
Before you buy, verify your fibre type is single mode and your connectors match LC and coaxial interfaces. Check that cabinet power can supply 750 mA bus current. Confirm the ambient temperature stays within 0 to 60°C.
