Low power, potential free, switching

[Warichet]

Hi,

Anyone knows about a very low power, potential free, switching actuator ? 4-6 channels ?
All the actuators I can see are switching at least 6A, what an overkill when all I want is switching a couple of mA.
So, I'm looking for a low cost alternative. I cheked Zennio, but they don't offer potential free, switching.

Thank you for any tip.

Have a look at:

Siemens

N 567/12 Schaltaktor N 567/12
8 x AC 230 V, 2 A

}

5WG1 567-1AB12 257,––

You might check this discussion in addition (one year old). Finally, the Siemens seemed to be the only choice besides making your own (what I did and wouldn't do a second time ...)

Siemens
N 567/12 Schaltaktor N 567/12
8 x AC 230 V, 2 A

Die Ausgänge schalten mit vier potentialfreien Kontakten

Vier ?!? and what about the "vier" others ?
178€ = still 22,25€/port

(what I did and wouldn't do a second time ...)

Aah ?
You burned your fingers ?
I guess it's a hell of a job, with much time investment.

Isn't this lack of devices a hole in the KNX market ? (unless almost nobody needs it)

Another solution:

KNX Universal Konzentrator
32 Outputs
about 3xx Euro

in combination with a number of Finder Relays.

Cheapest solution.

No. Done it before.

Yes. Too much time investment, even for me. See here.
