Thanks for the great information on circuit protection. Resettable as apposed to fuses, I like that.
Currently I am using an Intermatic programmable timer to turn on at 6pm and off at 10pm daily. The timer powers a receptacle with a train transformer and the current 5vdc power supply plugged in to it. The train transformer is only powering incandescent street lights and other lighted accessories that sit on shelves behind displayed trains.
My goal was to not have all of the building lights come on at the same time. The timing between lights turning on would be just a minute or two until all are building are lit.
Do the timing modules need to be powered all the time to retain the settings?
In your video the reed switch is providing the trigger to start the sequence. The two second delay on is the P1 time? The relay being energized for 10 seconds is the P2 time?
In your video application the trigger is momentary and it starts the sequence. If the trigger is constant could/would the removal of the trigger also start a timed sequence? Just wondering.
If I understanding the timer module, for my application I could use the intermatic timer to provide the trigger at a fixed time every day. Each timer module would be set with a different delay on time of say a minute or two. That would stagger5the light on. I would set the timer for minutes and a delay off time of 240 minutes (up to 999) would give me a 4 hour on time for the light. The lights would turn off in the same sequence they were turned on. First on first off.
I do have an optical triggered relay. Bought it at a train show a few years ago. Seemed like a cool idea. Haven’t figured out what to use it for yet.
