Multi Mode Timer (version II) - 8 to 8192sec (2.3h)

Documentation in acrobat format
Schematic to show how to connect two x CPS152 together to get very long duration timers - to 20 years

cps152.jpg
A 555 timer IC can be set to 1 second oscillation. The 555 output is fed to a 4020B ripple counter IC. Eleven time outputs from the counter is jumper selectable to an on-board relay. PCB dimensions: 58mm x 53mm. Power supply: 12VDC (CPS152)

Timer kit 2 - 555 pulse a counter
 
This is the classic 555 timer circuit switching a relay after a period of time determined by resistor & capacitor connected to the 555. The 555 is used as a monostable. Pot is used to set the time. You can chage the component values & treshold trigger.
