Product Functions
Data Centralization & Forwarding
- This Multi-Protocol Communication Panel (IEC 61850, Modbus) seamlessly connects multi-brand and multi-protocol intelligent devices such as protection units, power meters and temperature controllers. It converts original data into standard protocols and uploads information to dispatching platforms and background monitoring systems.
Network Construction & Redundant Communication
- Industrial switches build stable station-level and process-level network frameworks, enabling reliable data exchange between field devices and monitoring terminals. Network redundancy design effectively avoids service interruption caused by single-point faults.
Full-station Time Synchronization
- Timing devices receive satellite and upper-level clock signals, and distribute accurate time parameters to protection, measurement and fault recording equipment. It ensures precise fault analysis and consistent SOE event records for the whole system.
Protocol & Security Isolation
- Built-in isolation mechanism separates different network domains and communication protocols, greatly lifting overall system safety level.
Remote Operation & Diagnosis
- As a practical Real-Time Data Monitoring Communication Panel, it supports remote running status inspection of core components via network management software, facilitating rapid fault positioning and daily maintenance.
Product Advantages

- Standard cabinet specification: Unified appearance design allows side-by-side installation with protection and control cabinets
FAQ
Q：How to select communication panel？
A:How to choose a communication panel? Here are my personal opinions. It is advisable to select products from the same manufacturer for the communication panel, relay protection panels and the entire relay protection system of the power station, facilitating subsequent commissioning. Strictly follow technical documents, as specifications and configurations of communication panels vary by technical requirements. Blind selection may cause operational troubles in later use.
