Time Synchronization parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 32.768 kHz Crystal 1× 32.768 kHz quartz oscillator crystal rated ±20 ppm over temperature
2 Backup Battery 1× Lithium coin cell (CR2032 or equivalent) maintaining RTC for 5–10 years during power loss
3 RTC IC 1× I2C RTC IC (e.g., DS3231) with built-in oscillator and temperature compensation
4 NTP Synchronization 1× Firmware routine syncing RTC to utility master clock via wireless or PLC daily, drift <1 minute/year
