Digital-Input Modul 24V

[mamtho]

Hi there,
is there any existing Digital Input Module/unit which works with external 24V using something like optocoupler?

It should have up to 16 digital IO extension, each with an separate optocoupler.

So i can get 24V from any system like an Door closed Sensor.
Each Door has his own 24V.

It would be nice to extend this Inputs by combing more Moduls.
An Grove Unit would be also good, which i can extend with an Hub.

thx Thomas

I have the same question. Did somebody find a simple solution for this?

Concerning the additional I/O I use the EXTEND I/O modules, Provide a PaHUB if you need to use several.

For the inputs here is a solution with optocouplers:

For outputs, I've used this before:
