Please note that the activation voltage has no fixed polarization, therefore the terminal C1 can
be connected to a positive or negative voltage.

Digital outputs

There are two types of outputs: Q1 to Q4 are relay outputs, capable of switching 8A, and Q5 to
Q8 are open collector outputs.

The following diagram shows how to connect a lamp using Q1.
