The Flexcharge Real Time Programmable Timer is a 24 hour, 8 event ON, 8 event OFF clock based programmable 8A load controller. Multiple load ON and load OFF times are programmed into this real time clock controller. Each day can be programmed with its own unique timing pattern. Eight ON and eight OFF events can be programmed independently. Example, Use one ON event to have a light come on at 7 pm every day then use seven different OFF events to turn the light OFF at a different time each day.


  • Internal battery maintains clock and programmed memory for up to 3 yeas with no external power. (The battery will not operate the timer)
  • Consumes less than 5 mA in standby mode.
  • Drives up to 8A inductive Loads (motors, lights with ballasts) or 16 A Resistive Loads. Expandable with an external relay.
  • Isolated relay contacts allow user to directly control up to 240 VAC Loads
  • Reverse Polarity Protected
  • Manual override allows the user to manually turn the load ON and OFF as desired
  • Easy to Use Terminal Block for simple installation.
  • Easy programming of timer functions. Reset button to wipe out all settings if desired.

The clock circuit of the timer must have 12 volts to operate it but the timer will switch any voltage up to 240 VAC. Because the clock only draws 5 mA in standby and 45 mA when the load is ON, you can operate the timer from a 12 volt battery in the system but then switch any higher voltage. This works well on a 24 volt system.

Note the minimum ON time is 60 seconds.
