Schneider 140NRP95400

Product Overview

The Schneider 140NRP95400 is a dual-channel fiber optic repeater module designed for the Modicon Quantum automation system. Its primary function is to extend remote I/O network communications over long distances while maintaining high signal quality and immunity to electrical noise. It supports two independent multimode fiber channels with ST-type connectors, along with a coaxial connection interface. By converting and repeating signals between fiber optic and coaxial media, it ensures reliable data transmission across large-scale industrial facilities.

This module is typically installed within Quantum racks and connects to other repeaters or remote drops in a distributed control network. It is built to operate in demanding industrial environments and is certified to meet rigorous safety and performance standards. With a transmission range of up to 3 km over appropriate fiber types, it is a key component for applications where long cable runs and robust communication integrity are essential.

Key Features

• Dual Independent Fiber Channels
  Two fully separate fiber optic channels allow flexible topologies—supporting redundant paths for high availability or separate communication links for segmented systems.

• Long-Distance Communication Capability
  Capable of transmitting signals over distances up to 3,000 meters using suitable multimode fiber (e.g., 100/140 µm core), ensuring reliable connectivity in large facilities.

• Multimode ST-Type Fiber Connectors
  Uses industry-standard ST connectors for secure, low-loss optical connections that are straightforward to install and maintain.

• Coaxial Interface for Hybrid Networks
  Includes a BNC coaxial port, enabling seamless bridging between copper-based coaxial segments and fiber optic links.

• Industrial-Level Electrical Performance
  Low optical signal rise and fall times (around 20 ns) ensure rapid, accurate data transmission. The receiver sensitivity of approximately –30 dBm and a dynamic range of about 20 dB provide stability even with varying optical signal strengths.

• LED Status Indicators
  Front-panel LEDs display optical link status, coaxial communication status, activity signals, module readiness, and fault conditions—enabling quick diagnostics without specialized tools.

• Low Power Consumption
  Operates at around 5 W with a 5 V DC supply, drawing approximately 700 mA. Designed to minimize energy load on the system power budget.

• Rugged Industrial Design
  Built for continuous operation in environments from 0 °C to 60 °C, withstanding storage temperatures down to –40 °C and humidity up to 95 % non-condensing. Certified to standards such as UL 508, CSA, FM Class 1 Division 2, and TÜV.

• Compact Rack-Mount Module
  Fits easily into Modicon Quantum racks, measuring roughly 40 mm wide, 250 mm high, and 104 mm deep, with a weight of about 0.55 kg.

Applications

• Extended Remote I/O Networks
  Used to link remote I/O drops over distances exceeding the limitations of copper cabling, common in sprawling manufacturing plants or multi-building sites.

• Harsh Electrical Environments
  Ideal for facilities with significant electromagnetic interference, where fiber optic transmission ensures immunity to noise.

• Redundant Communication Paths
  The dual-channel capability supports designing redundant network loops, minimizing downtime in case of a single link failure.

• Industrial Campuses and Utility Sites
  Suited for oil and gas facilities, water treatment plants, and power stations where long-distance, interference-free communication is critical.

• System Expansion and Retrofits
  Enables existing Modicon Quantum systems to be expanded without replacing the primary control hardware, making it cost-effective for gradual upgrades.
