Is it any modules that can control 12v relay switches via the profilux 4?
I have been reading the 1-10V only can support 20ma, and thats not a good thing, but using the 1-10V to trigger a relay could work. Any electronic relays that work with the 1-10V port? (or relay modules that is dedicated for this use).
(to control things like solenoid valves etc without using a transformator or a 220v solenoid).

Caution: outputs per charge only 20mA, do not forget free wheeling diodes!
You can also use S port

Is the S port also limited to 20mA or is it the same?Quote:

Can you suggest a free wheeling diode that would work with the 20ma limit of the GHL?Quote:

Any 1N4001 diode like is ok.
I have 1N4007 will those work?
Yes, i use personally use 1N4007
So circuit is 12v + relay output from ghl then a 1n4007 on each lead then a Finder 43.41.7.012.2000?
Anyone who can help me with my last question so I can make the correct circuit :)
