A Capable & Inexpensive Digital Timer
I recently came across a
single board timer with a 3 digit LED display at a good price
that appeared to have capabilities that make it ideal for many
model railroading applications. It is designed to activate a
relay for a set number of seconds then turn the relay off for
another set number of seconds. Both of these times (time on and
time off) can range from 1 second to 999 seconds and are clearly
shown on the red LED display making setup a snap. |
