The master clock maintains high-precision standard time and generates synchronized time pulse signals.www.plcva.com
Transmit uniform timing pulses to all distributed slave clocks across the vessel to ensure all slave clocks show identical time.
Slave clocks receive pulse signals from the master clock and synchronize local time display.
Built-in fault monitoring: alarm if pulse signal loss or master clock abnormality occurs.
Adapt to marine environmental conditions including vessel vibration, humidity and temperature fluctuation.www.plcva.com
