Relay Output on Orange Cube - need help

Cube Autopilot
#1

Hello everybody,
I have an pixhawk orange cube as arducopter, and I wanted to activate Aux Out 5 as a relay.
I also set the parameters in Mission Planner:
BRD_PWM_COUNT = 4
AUX out was set to 54, relay 2
And when I go into the Flight Data menu and want to test the Relay 2 function, nothing happens, only with servo output No.13, there I get a voltage change when clicking, between 0.1 - 0.3 V
How does this relay output work? Is this an open / close contact? Or how should it work this relay output? Do you need an additional relay board?
Where exactly do you have to connect the contacts?
I want to turn a headlight on and off.
Don’t understand the logic behind it.

Thank you for!

It outputs 3.3V.

thanks, but on which pins exactly must be connected to get this 3,3Volt?
See my scheme/pictures with the connectors.
For example, i need a relay output on Aux 5

GND and Signal.
What do you want to use relay on?
You can set it high/low. That is 3.3V or 0V. If it’s triggering, You can send a 3.3V pulse.

thanks, i wann use a relay, that activated one LED BEAM for example, or a separate camera trigger
Where can I set the high/low parameter?

It works for triggering camera for sure. For LEDs make sure your voltage levels are matched or you can also use external relay.
