Dear all
I recently got myself a GLH profilux 4 and a breakout box.
For now I'm just using to monitor the tank.
I run a lot of DIY stuff, mostly out of arduinos. The idea is to slowly change them to the profilux.
The first to go will be the DIY light controller (1-10v). That's pretty easy to control with the profilux and the GHL connect app.
However, I cant figure out how to control relays.
According to the breakout box, each L-port can control 2 relays and 2 1-10v. Does anybody know how to program the relays using the GHL connect app?
The 1-10v I can do under illumination.

Also, does anyone have the schematic for the float switch connectors? I have a lot of them around, so I may play with them at some point.

Thank you all.

For the moment forget the L-ports relays. They are for old dimmable (1-10 V) drivers that did not get all the way to zero. They normally is in use together with EVG-AP-2F-HIC and these relays will cut of the power when the illumination is zero - as I understand. I have used them that way with old LED drivers that still get some current when the signal was 1 V. If you want to use them - all Illumination (dimmable) over 0 will activate the relay (as I understand it)

You should more concentrate on your S ports (I hope it is not P4E you bought because they have not the S ports) The S ports can control 4 of relays. Do you use S 1-4 - you will find this in socket 1-4 at the switchable sockets meny, if you use S 5-8 - you will use switch 5 - 8 in the switchable sockets menu. It is important that you not have configure any PAB power bars to those switches in the meny.

Hi Lasse
Thanks for the answer.
Of course I have the 4e
Anyway according to the picture above you still have two relay controls with the l ports. I just can't figure out how to activate them with the ghl connect app. Would they still be in the switchable socket menu?

Once again, thanks

Yes - and as I remember (it was more than 7 years ago) - they get activated when the illumination channel connected to the L port was above 0. If you connect Ill channel 1 to L1 - the relay 1 will be activated as soon as the brightness is over 0 and deactivated when the brightness is below 0. The 1-10 V signal also manage the on and off stage of the relay

I send with the manual for the EVG-AP-2F-HIC - you maybe get some ideas from there

This was relays that´s was connected with L-ports and it was GHL:s own "extension" card EVG-AP-2F-HIC.

With the S-ports - I suppose you can use all type of relays that that have a control voltage of 12V DC and max 100 mA .

Oh ok.. so for wiring, would you connect all the relays to pin 1 and then each one to the respective relay pin (1 to 4)?
Would this basically be like using a powerhub, except that you have to have an external power supply?

If I understand it right - not pin 1 but pin 6 (GND) Each of 2 - 5 have its own + 12 V source If you use S (1-4) as a source -
If you activating switch channel 1 (in your profilux) it will send +12 V through pin 2 - pin 2 further connecting to the + pole on the control part of the relay. The minus connected to GND (pin6). The current (when pin 2 is activated) will have the control part of the relay to switch on the load part. The load part can be whatever in voltage. It could be a source between 0 - 240 V AC or DC, Yes it will be the same as if you use a 4 outlet power bar of the old model but without a given voltage for the load.

In some way it will act as an powerhub but the real power hub use GHL PAB protocol not the on/off behavior of the S (1-4) and S (5-8) ports

Please @Vinny@GHLUSA correct me if I´m wrong
