Core Functions and Technical Advantages

Dual-protocol data exchange
Supports both Modbus RTU (serial) and Modbus TCP (Ethernet), enabling flexible communication with different external control and monitoring systems.

Flexible data mapping
Modbus register addresses and data content can be freely configured. Measurement values, alarm states, and diagnostic information from all modules within the 3500 rack can be uploaded on demand.

Multiple interface adaptation
Ethernet is used for high-speed data transmission and remote configuration, while RS-485 supports fieldbus applications and long-distance communication.

Industrial-grade reliability
Designed for wide operating temperature and voltage ranges with strong electromagnetic interference immunity. Suitable for harsh industrial environments, with MTBF > 100,000 hours.

Convenient configuration and maintenance
Supports remote parameter configuration via 3500 rack configuration software. Front-panel LED indicators enable rapid identification of communication faults and support online diagnostics.

System-level integration capability
Aggregates the global status of the 3500 system, enabling centralized monitoring and linkage control with DCS and PLC platforms.

Core Application Scenarios

Power generation
Integration of steam turbine generator 3500 systems with DCS/DEH platforms, uploading real-time parameters such as vibration, displacement, and speed.

Oil and gas
Uploading compressor and pump condition data to SCADA systems via Modbus to support predictive maintenance and condition-based monitoring.

Chemical industry
Centralized monitoring of rotating machinery groups, with linkage to Safety Instrumented Systems (SIS) for rapid fault response and improved plant safety.
