TM221CE16R Calculation Issue

There are numerous examples for when to use them.....Normally it is to trigger something like a counter or a pulse timer or set or reset a coil. Sometimes you dont care what the condition of something is you just want to know when it switched on or off

Hi again,

Does anyone of you know what is the function of rising and falling edges? I essentially want to trigger a timer once a coil is turned off, after being on.

Thanks guys

Maybe you should use falling edges with TOF Timer to solve this.

I haven't really understood it unfortunately I guess.. I essentially want to run M1 for 9 seconds once M0 goes to LOW, from HIGH..
