This circuit is a cyclic timer, with independently adjustable ON and OFF
periods. The ON and OFF periods can be adjusted via two PC board mounted
trimmer potentiometers from a few seconds to approximately 30 minutes. It
includes a relay which can handle loads of up to 3A / 110V AC or 24V DC.
Supply voltage: 9V DC /
100mA
Timing adjustment:
ON period from a few
seconds to 30 minutes
OFF period from a few
seconds to 30 minutes
