- Operating voltage: Typically 4.5 V to 5.5 V (designed for standard CMOS levels).
-
Power supply: Can be powered directly from the AC mains via a series resistor or by direct current (DC).
(WARNING: INSTALLATION MUST BE PERFORMED BY A QUALIFIED PROFESSIONAL) - Internal power consumption is in the microampere range (excluding triac gate current).
- Time base (frequency reference): Designed for 50 Hz or 60 Hz mains (internal frequency division by 1:50, 1:60, 1:10, and 1:3).
- Output type: Open-collector output (Pin T), synchronized with the zero-crossing switch for direct drive control of triacs or relays.
- Maximum output current : Capable of switching drive currents up to 100 mA.??
Time programming & logic
- Time range: Adjustable delay times from 1 second up to 31.5 hours.
- Programming: The selection of the 8 fixed base times is performed in binary via logic control inputs A, B, and C.
- Multipliers: Fixed time increments (base time unit × 2, × 4, × 8, × 16, etc.) are mask-programmed or configured via pins D, E, F, G, H, and I.
- DIP18 package
