常见问题

What is the primary function of a timestamp circuit in industrial error logging?

To provide accurate, synchronized time records for machine events and failures, enabling precise maintenance scheduling and root cause analysis.

How does the timestamp circuit maintain accuracy during power outages?

Through lithium battery backup that powers the RTC chip independently, preserving timekeeping functionality until main power is restored.

What time synchronization methods are used?

Typically GPS time signals or network time protocol (NTP) synchronization, with some systems using radio time signals for facilities without network access.
