2. Optical-Electrical Conversion and Signal ExtensionЦена тепловых реле перегрузки серии Chint NXR

The BMXNRP0201 converts electrical signals (RJ45) to optical signals (LC interfaces) and vice versa, addressing signal attenuation in industrial environments for long-distance transmission (например, over 100m). Например, in factory automation, if the distance between two I/O substations exceeds 100m, the BMXNRP0201 enables fiber connection to ensure data real-time performance and reliability.

2. Redundant Communication SupportЦена сетевого фильтра CHINT

When used with Schneider CRA (BMECRA31310) модули, it can build redundant Ethernet links to enhance system reliability. For instance, in waste-to-energy control systems, dual fiber paths achieved via BMXNRP0201 and CRA modules ensure uninterrupted communication for critical equipment (например, incinerator control).

3. Hot Swapping and Plug-and-Play

It supports hot swapping, allowing module replacement during system operation without shutdown, reducing maintenance time. The module is plug-and-play, seamlessly integrating with Schneider PLCs without complex configuration.

4. Industrial-Grade Reliability

Adopting Green Premium environmental design, compliant with RoHS, REACh, и т. д., it has strong electromagnetic interference (EMC) resistance, suitable for harsh industrial environments with dust, oil, and vibration.

III. Сценарии применения

1. Промышленная автоматизация

Remote I/O Connection: In automotive manufacturing workshops, the BMXNRP0201 connects distributed I/O modules (например, sensors, actuators) to PLCs, enabling cross-workshop data transmission and replacing traditional copper cables to reduce signal interference.

Process Control: In chemical production, it connects distributed control systems (DCS) with field instruments (например, flowmeters, control valves), supporting Modbus TCP/IP protocol to ensure real-time data collection and command issuance.

2. Energy and Power Systems

Substation Automation: Connects protective relays, smart meters, and other devices to monitoring systems via fiber, enabling remote fault diagnosis and power dispatching over a transmission distance of up to 15 km.

Renewable Energy: In wind farms, it connects wind turbine controllers to the central monitoring room, transmitting large volumes of data (например, wind speed, power generation) via fiber, with significantly better EMC resistance than copper cables.

3. Intelligent Buildings and Transportation

Building Automation: Connects access control systems, elevator controllers, security cameras, и т. д., to build campus-level IoT, supporting long-distance transmission (например, cross-building connections).

Rail Transit: Used in metro signal systems to connect wayside equipment (например, signals, switch machines) with the control center, ensuring high real-time performance and reliability.

1. Installation and Configuration Key Points
2. Hardware Installation

Монтаж на рельсе: The module directly mounts on a 35mm AM1 ED rail, requiring good ventilation to avoid high-temperature environments.

Fiber Connection: Use single-mode fiber (9/125μm), and it is recommended to select industrial-grade optical cables compliant with IEEE 802.3u standard to avoid signal loss due to excessive bending radius.

Grounding Requirements: The module must be reliably grounded (ЧП) with a grounding resistance ≤4Ω to reduce electromagnetic interference.

2. Software Configuration

Network Parameter Setting: Configure the module’s IP address and communication protocol (например, Modbus TCP) via Schneider Unity Pro software, and associate it with the PLC’s I/O mapping table. Например, in an M580 PLC, set the BMXNRP0201’s optical port to “100Mbps full-duplex” mode.

Redundancy Configuration: If used with a CRA module, enable PRP (Parallel Redundancy Protocol) in the software, set primary and backup paths, and ensure automatic switching during faults.

3. Fault Diagnosis

LED Indicators: Judge link status via green LED (например, “LNK” on indicates link connectivity, “ACT” blinking indicates data transmission).

Logs and Alarms: View module diagnostic logs in Unity Pro to locate issues like communication interruptions or fiber faults, and replace fibers or modules if necessary.

2. Compatibility Verification

Ensure BMXNRP0201 is compatible with PLC models (например, X80, M340) and firmware versions, referring to Schneider’s official compatibility list.

2. Fiber Selection

Single-mode fiber (SM) is suitable for long-distance transmission (например, 15 km), while multimode fiber (MM) is for short distances (например, 550 м). To extend the distance, cascade multiple BMXNRP0201 modules.

3. Redundancy Design

In critical applications (например, petrochemical, nuclear power), adopt dual fiber paths and CRA modules for redundancy to avoid single-point failures.

1. Typical Application Case

In a hot-rolling production line of a steel plant, BMXNRP0201 connects remote I/O substations with the central PLC (Modicon M580). Due to the large span of the production line (примерно 2 km), traditional copper cables could not meet signal transmission requirements. By converting electrical signals to optical signals via BMXNRP0201 and using single-mode fiber transmission, stable real-time data interaction (например, mill speed, temperature monitoring) was achieved. Кроме того, a redundant link built with the CRA module ensured continuous system operation during fiber faults, reducing downtime by approximately 30%.
