The idea is to have simply changeable timer interval

Some LOGO! can measure a 0-10 Volt signal as a anaolg input. Somtimes u have to use a extra LOGO! module (pe the AM2) Connect a 10 Volt power to teh potmeter, and the loper can connectd to the Analog input. 2/ set 'setpoint' time for on-delay timer Yes also to other timers etc. 3/ for example Min-max analog range matches 1s-5s delay Not directly, but there are al lot of timers in the LOGO so you can program it easy 4/ trigger the timer from some event, for examplebinary input. Yes thats very easy.
