Duex 5 control relay
-
Hey guys,
I would like to control a relay via the GPIOs of the Duex 5. If done that before on another printer. The problem is that its not working on the Duex 5. I got 5 V on the GPIO pin but the relay is not switching.
If I grab 5V from the duet2 the relay is working. If I grab 5V from the Duex5 it is not working.
I have nothing else on the 5V rail at the moment.Maybe relevant: I am using the 12V from the Duex5 to power an Arduino Nano but that should not make a difference.
According to the datasheet the Relay takes about 80mA.

https://www.farnell.com/datasheets/1870236.pdfSo my question is:
Why?Custom ANET A8

@taconite said in Duex 5 control relay:
If I grab 5V from the duet2 the relay is working.
Do you mean using +5V from the Duet 2 and switching the -'Ve side of the relay from the Duex5? The 5V on the Duex5 is supplied by the Duet2 so its the same supply.
Can you show a diagram of how you have it wired when its working, and when its not. also post how you are configuring it in both cases.

Hey Toni,
As per standard the positive side of the relay should to be switched.

mh strange now from the 5V fo the GPIO Header it is working but again not from the GPIO 3 pin. but I measure 4,7 V from GPIO 3 to GND

According to the datasheet the Relay takes about 80mA.
the GPIO pins are driven from a SX1509B
https://www.mouser.com/datasheet/2/761/sx150x_89b-1283302.pdf
so they are sourcing max 8mA
you may need to switch the -'ve side using one of the fan mosfets.
-
wow okay 8mA is very little you may want to think about upgrading this in the future otherwise they are pretty much useless. That is very unfortunate. I really don't understand why GPIOs did play so a little role in the board design as this is often needed for flexibility. And in terms of flexibility Duet always showed off.
You may want to add that to the wiki pageUnfortunately all fan outputs are used.
Is it possible to use a heater output? That should work like this, right?M950 P4 C"e1.heat" M42 P4 S1but than it would be 24V instead of 5V if I am running a 24V-system, correct?
Are they active high on bootup aswell?Could you recommend a transistor that I could just patch in between?

@taconite you can use a heater output to switch the -'ve side, just leave the +'ve side connected to the 5V.
-
the problem is, that I have a manual button that I would like to use as well. With the GPIO I could have just run them in series. With the low side switching via the heater output that's not possible, or is it?

@taconite do you mean a manual button to turn the relay off when it is on, like an override/cutout. You can cut the supply with a button in series on the -'ve side as well.
