how to select 1 input analog signal out of 12

Post by adewavrin »

Dear all,
In our project we have 12 analog voltage input signals (thermo measures - range 0 to 1v) that we want to measure in turn, every minute.
The selected input signal has to go through a stabilizer circuit (jenco) before it's measured with an ADC
So we have to let only ONE signal go through a 12-to-1 selector.

We plan to use :
-revpicore for software,
-revpiADC for measurement of the selected input voltage,
-revpiDO to control a multiplexer.
but we still miss a multiplexer to select which of the 12 input signals arrives on the ADC

My question is : does kunbus sell such a device ? If not, what would you use ? A power relay like (https://images-na.ssl-images-amazon.com ... 3U0b5S.pdf) would be a little bit overkill I believe...
Thanks in advance,
Anselme

Dear adewavrin, we at KUNBUS unfortunately do not offer such a multiplexer hardware.
