Door activated power on
Posted: Thu Sep 27, 2012 4:25 pm
I have a fit-pc that I need to power on/off based on a door opening/closing. I can fairly easily have the door trigger a relay which will in turn power up the fitPC taking advantage of the auto-on feature. However, my concern is the door closing and abruptly disconnecting power to the fitPC.
I started looking at some programmable relays that I could put in line between the power source and the fitPC. The programmable relay could power up the fitPC based on the door switch. I also have some general purpose IO board connected to the fitPC that I use for other monitoring. I could have the fitPC tell the relay to disconnect power after some delay when ready to shutdown.
Is this the way to go or is there a simpler way that I am overlooking?
