Performance & Structural Characteristics
This communication module adopts dual-speed data processing mechanism, separating high-speed fixed I/O signal transmission and secondary Modbus data packet processing to avoid data congestion and ensure real-time system response. The redundant Ethernet design effectively prevents network disconnection failures and improves system operational stability. Conformal coating enhances environmental adaptability, resisting harsh interference such as temperature fluctuation, dust and electromagnetic noise in power plants. It supports flexible protocol and channel configuration to adapt to diverse external device communication demands. With integrated self-diagnosis indicators, it enables real-time working status monitoring and rapid fault locating. It supports long-term 24-hour continuous operation and features low failure rate and convenient maintenance.
