This schematic shows how to switch a smoke generator with a relay:

I bought a relais with 5 poles.
1 pole NO
1 pole NC
1 pole COM
And two poles with nothing written on it.
Must i connect all 5 poles or just 4.
And how do i connect the poles?

You need only 4 pins:
  • NO -> Battery +
  • COM -> Smoker
  • 1. "unwritten" pin -> X1/8
  • 2. "unwritten" pin -> X1/9

To the "COM" pin of the relay. I've improved the schematic.

Hello, I find this very interesting. I have a smoke generator with a fan that controls the amount of smoke with the speed of the ship model. So I have 4 wires, 2 for the heater and 2 for the fan. I found the sheme for the connection of the heater with the relais module, but were do I connect the wires for the fan?

Thanks

Hello,

you can wire the fan in parallel to the heater so that only one output is required. Alternatively you can define two outputs for your smoke generator:
- Smoke generator heater
- Smoke generator fan

The 2nd output functions similar to the 1st one except that it has a configurable power-off delay timer (0-255 sec) to blow out the remaining smoke. See also the manual on pages 53 and 79/80.

If the power consumption of the heater and fan does not exceed 1,5A each (total 3,0A for the whole sound module) you may connect those directly to the output. Don't forget to add a flywheel diode between fan output and positive supply if the fan does not have an internal diode.
If the power consumption is higher use a relay module as described in the previous posts, but in this case the output options can't be used and must all be set to 0 or 100% since the output controls the relay only.

Possibly the heater may require a relay module but perhaps the fan can be driven directly from the output so that you can use the options for the fan at least.
