Product Details
Hardware Architecture
Overall structure of the module
140NRP95400 Fibre Optic Repeater adopts the Modicon Quantum series standard modular design, and its external dimensions and installation structure comply with the Quantum backplane specification. The module is mechanically fixed to the system rack through the backplane connector, for power acquisition and internal signal connection, facilitating unified layout and maintenance in the automation system.
Backplane interface unit
The rear part of the module is equipped with a standard Modicon Quantum backplane interface:
Obtain the system power supply through the backplane interface
Realise the internal signal connection with the PLC CPU or communication module
No separate external power supply is required
The backplane interface also undertakes the data path function, enabling the module to directly participate in system communication as a physical layer device of the network.
Module housing and mechanical design
Industrial-grade plastic casing with certain mechanical strength
The shell design is suitable for installation inside industrial control cabinets
The front panel integrates interfaces and status indication areas
The module supports quick plugging and unplugging, and the replacement operation is convenient
Optical fibre interface assembly
The front end of the module integrates an optical fibre communication interface for the transmission and reception of optical signals.
Independent optical fibre transmitting end and receiving end
The interface structure meets the requirements of a stable connection in industrial sites
Support reliable fixation of optical fibre plugs to reduce the risk of vibration or misinsertion
The optical fibre interface is the core hardware unit for the module to achieve long-distance communication and electrical isolation.
140NRP95400 Fibre Optic Repeater Communication Interface Characteristics
1. Types of optical fibre communication interfaces
The 140NRP95400 adopts an industrial-grade optical fibre communication interface and is used to achieve optical fibre transmission of network signals in the Modicon Quantum series of automation systems. The module converts the electrical signal on the backplane into an optical signal for transmission through photoelectric conversion technology and completes the reverse conversion at the receiving end.
This communication method is suitable for long-distance industrial field environments with high anti-interference requirements, and can effectively reduce the impact of electromagnetic noise, surge voltage and grounding differences on communication quality.
2. Supported communication media
Optical fibre is adopted as the transmission medium
It is compatible with the commonly used types of optical fibres in industrial automation systems
Compared with traditional copper cable communication, optical fibre transmission can maintain stable data transmission characteristics in complex industrial environments
The specific type of optical fibre and connection method should be selected based on the overall design of the system.
3. Communication distance and signal relay capability
The 140NRP95400, as an optical fibre repeater module, is mainly used to extend the network communication distance.
The module regenerates and shapes the incoming optical signal
Compensate for signal attenuation generated during long-distance transmission
Support network segmented deployment to reduce the distance limit of single-segment communication
Cross-regional communication can be achieved in large-scale automation systems through relay methods.
4. Network topology adaptability
This module can be used in various industrial network topologies, including but not limited to:
Point-to-point optical fibre connection
Segmented expansion of linear topology
Remote node connections in a star structure
The specific topological structure is determined by the system controller, I/O distribution mode and on-site network design. The module provides reliable optical fibre communication support for the network at the physical layer.
5. Communication rate and data transparency
The module operates at the physical layer of the communication network
Keep the uploaded and downloaded data content transparent, and do not parse or modify the data frame structure
It does not participate in the communication management of the protocol laye,r but is only responsible for signal transmission and regeneration
Therefore, the communication rate and protocol characteristics are determined by the Quantum network system to which it is connected, rather than being limited by the module itself.
6. Electrical isolation characteristics
Opticafibreer communication interfaces provide natural electrical isolation capabilities:
It helps to isolate the potential difference between different grounding points
Reduce the impact of lightning strikes, surges and electromagnetic interference on communication systems
Enhance the overall safety and reliability of the system's operation
This feature is particularly important in industrial environments such as power, metallurgy, and chemical engineering.
7. Status monitoring and interface indication
The module is equipped with communication-related status indication functions to reflect the working status of the interface:
The status of the optical fibre link establishment
Data sending and receiving activity status
Indication of a communication anomaly or link interruption
The indicator light can assist on-site personnel in quickly determining whether the communication link is normal.
8. Interface relationship with the Modicon Quantum system
The module is connected to the PLC CPU or communication module for data through the Quantum backplane
The optical fibre interface serves as an external communication extension of the system
It does not occupy additional logical communication resources or software addresses.
