Communication Interfaces:Ethernet,RS-485,and fieldbus interfaces(such as PROFIBUS and Modbus).
Features
Time Synchronization:The module features a built-in real-time clock(RTC)that supports millisecond-level time synchronization and is compatible with standards such as NTP(Network Time Protocol)and IEEE 1588(Precision Time Protocol).It enables cross-device time calibration via Ethernet or dedicated buses.It also supports dual clock source backup,automatically switching to the backup clock in the event of a master clock failure,ensuring time continuity.Event Logging and SOE:Supports recording of thousands of events with a resolution of 1ms,adding precise time stamps to each event for easy incident analysis,fault tracing,and system optimization.Event logs can also be exported via USB,Ethernet,or dedicated interfaces,making them compatible with mainstream data analysis tools.
Hardware Interface and Expandability:Supports expansion with digital/analog input and output modules,enabling connection to external sensors and actuators for time synchronization and control linkage.With an IP20 protection rating and DIN rail mounting,it is suitable for indoor,dry environments.
Application Areas
Power System Time Synchronization:In power plants and substations,it synchronizes time among relay protection devices,fault recorders,and measurement and control units,ensuring data consistency across devices during incident analysis and supporting time calibration in black start scenarios.
Industrial Automation Process Control:In process industries such as steel,chemicals,and papermaking,it provides a unified time base for distributed control systems(DCSs),optimizing the timing accuracy of logic such as batch control and sequential control,and supporting time coordination for multi-device collaborative operations.Event tracing and fault diagnosis:In safety-critical areas such as rail transit and mining machinery,events such as equipment operating status,protection actions,and operating instructions are recorded to provide time-accurate data support for accident analysis.
