From Unofficial Stationeers Wiki
This is the schematic/circuit to make a timer for other circuits.
It could, for example, be set to cycle every 10 seconds, and another circuit could use this to turn on a beacon for 2 seconds every 10 seconds.
In this exact implementation, by using an "equal", if for "some reason" the value goes over the max value, it will never reset.
It takes 85W to run.
