Counting thermostats opening and closing

Counting thermostats opening and closing

Counting thermostats opening and closing

I've made a test rig that tests thermostats opening and closing.

I have fifteen stats on test. I'd like to count the switches opening and closing. Can I put a small DC voltage through the switches and measure this going from +V to 0 and counting the pulse.

Is there something on the market I could use? Nice and simple as I am a meterials engineer not a programming/hardware wizard!  

RE: Counting thermostats opening and closing

A dry contact counter will count the simple opening and closing of a switch, no voltage involved.  Ideal for thermostat testing.  We use these on our cycle test rigs.  They are very reliable and won't introduce anomolies into other electrical equipment.


It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.
