Technical Specifications Dual independent communication channels; Ethernet and serial interfaces; Modbus TCP/IP and Modbus RTU protocol support; automatic redundant switchover; 24V DC power supply; operating temperature 0°C to +65°C.
Functional Features Redundant communication operation; automatic failover switching; load sharing; link status monitoring; seamless switchover without data loss.
Application Scenarios Critical machinery protection systems, power plant turbine monitoring, offshore platform equipment monitoring, high-availability process control systems.
Performance Parameters Millisecond-level redundant switchover time; zero data loss during switchover; high communication reliability; stable long-term operation.
Material Composition Metal shielding chassis, dual redundant communication circuits, gold-plated connectors, industrial grade components.
Structural Characteristics Rack plug-in module, front channel status and fault indicators, rear dual communication interfaces and backplane connector.
Working Principle Two independent communication channels operate in parallel. When the primary channel fails, the system automatically switches to the backup channel to maintain uninterrupted data communication between the monitoring system and upper-level systems.
Installation Requirements Install in designated redundant communication slot; connect both primary and backup communication cables; configure redundant parameters via system engineering tool; test failover function before commissioning.
Usage Notes Test redundant switchover function periodically; do not disconnect both channels simultaneously; follow network security management procedures.
