I need help on designing a sequential timer to switch on and off
atleast 3 relays in a particular sequence using timer ic.Thank You!

Far less components to do this with a small microcontroller and capture
the timing logic in code. This scheme also allows for far easier
inclusion of user control switch inputs, LEDs, and possible other
display device such as an LCD module.
