K8055 Extend inputs

Hi everybody,

I develop an application with this card (WINDEV language) to control 4 digital inputs…it works fine !

Now, my problem is that my complete project is to manage 4 modules (so 16 input controls)…but not at the same time.

So, it’a a probleme because i need to “open again” the 4 inputs of the actual module if i want to control the next one.

Look : pagesperso-orange.fr/amadjo/images/pg.jpg

What can i do ?

  • Connect 4 K8055…expensive and i am sure that it’s possible
  • Using the digital outputs with a k2633 (so do i will have enough current ?)
  • Using the analogic outputs with a bridge of resistances (but how ?)

Thank you for your help

You may also use the digital outputs of the K8055 to select (activate) one of your modules 1 to 4 - maybe…
