Core Functions and Technical Advantages

Real-time data exchange
Based on the EGD (Ethernet Global Data) protocol, providing millisecond-level response to meet the real-time control requirements of DCS and PLC systems. Supports bidirectional production and consumption of data.

Flexible data configuration
Customizable data groups including measurement values, alarm states, and diagnostic information. Update rates and priorities can be configured to match the requirements of external control and monitoring systems.

System-level status integration
Aggregates data from all modules within the 3500 rack, enabling centralized monitoring, data sharing, and remote diagnostics at the system level.

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 diagnostics and maintenance
Front-panel LED indicators enable rapid identification of communication and operational faults, while supporting remote configuration, diagnostics, and troubleshooting.

Core Application Scenarios

Power generation
Integration of steam turbine generator 3500 systems with DCS/DEH platforms for real-time monitoring of vibration, displacement, and other critical parameters.

Oil and gas
Uploading data from 3500/70M and 3500/77M reciprocating compressor modules to SCADA systems to support predictive maintenance and condition-based monitoring.

Chemical industry
Centralized collection of rotating machinery status data with linkage to Emergency Shutdown Systems (ESD) for improved safety and operational reliability.
