# Signal Inputs

he VAN PI Core is equipped with 8 isolated input signals, designed to provide versatile control over the relays or LEDs through the Dimmy interface. These input signals accommodate a voltage range from 6V to 30V, ensuring compatibility with various control systems. For proper operation, **it is essential to add a ground** connection to the 10-pin connector for the signals. This ground can either be tied to your system ground or to a separate isolated ground, depending on your specific requirements. 

You have the flexibility to use either a switch for permanent changes or a button as a trigger signal. You can find the configuration options for these inputs on the web interface under **Config -> Switches -> Inputs**. By following this guideline, you can ensure reliable and stable performance of the VAN PI Core in your applications.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://pekaway.gitbook.io/van-pi/connecting-devices/signal-inputs.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
