2. Optical-Electrical Conversion and Signal ExtensionPrix ​​des relais de surcharge thermique série 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 (par ex., over 100m). Par exemple, 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 SupportPrix ​​​​du parasurtenseur CHINT

When used with Schneider CRA (BMECRA31310) modules, 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 (par ex., 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, etc., it has strong electromagnetic interference (EMC) résistance, suitable for harsh industrial environments with dust, oil, and vibration.

III. Scénarios d'application

1. Automatisation industrielle

Remote I/O Connection: In automotive manufacturing workshops, the BMXNRP0201 connects distributed I/O modules (par ex., 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 (par ex., 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 (par ex., wind speed, power generation) via fiber, with significantly better EMC resistance than copper cables.

3. Intelligent Buildings and Transportation

Automatisation des bâtiments: Connects access control systems, elevator controllers, security cameras, etc., to build campus-level IoT, supporting long-distance transmission (par ex., cross-building connections).

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

1. Installation and Configuration Key Points
2. Hardware Installation

Montage sur rail: 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.

Exigences de mise à la terre: The module must be reliably grounded (PE) with a grounding resistance ≤4Ω to reduce electromagnetic interference.

2. Software Configuration

Network Parameter Setting: Configure the module’s IP address and communication protocol (par ex., Modbus-TCP) via Schneider Unity Pro software, and associate it with the PLC’s I/O mapping table. Par exemple, 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 (par ex., “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.

1. Précautions
2. Compatibility Verification

Ensure BMXNRP0201 is compatible with PLC models (par ex., 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 (par ex., 15 km), while multimode fiber (MM) is for short distances (par ex., 550 m). To extend the distance, cascade multiple BMXNRP0201 modules.

3. Redundancy Design

In critical applications (par ex., 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 (environ 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 (par ex., mill speed, temperature monitoring) was achieved. En plus, a redundant link built with the CRA module ensured continuous system operation during fiber faults, reducing downtime by approximately 30%.
