Large-capacity capacitor Clock data is retained using the power accumulated in a large-capacity capacitor incorporated into the PLC. When voltage of the large capacity capacitor drops, clock data is no longer accurately retained. The retention period of a fully charged capacitor (electricity is conducted across the PLC for at least 30 minutes) is 15 days (ambient temperature: 25℃). How long the capacitor can hold the data depends on the operating ambient temperature. When the operating ambient temperature is high, the holding period is short. |
