DUET 2 WIFI, RELAY CONTROL VIA GPIO

Gianluca

I connected the relay to the board, as shown in the figure, I added the command M950 F4 C "exp.heater7" Q500 in config.g and I wanted to switch the relay on and off through M42 P7 S1 and M42 P7 S0.
However, it is currently not working ...

thank you for the advice.

@gianluca ~~are you sure that you can switch this relays with 3.3V~~ Ok i have overlooked the datasheet from the relays and this is working between 5 and 12 V not with 3.3V

With M950 F4 you have created a fan#4.
So you have to use M42 P4 S1 afterwards, for switching on the relay.

DIY-O-Sphere

@gianluca
You can control that typ of relay with the PS_ON pin.

Gianluca

@siam I tested the relay with the raspberry PI 4 and it works perfectly powered at 3v

Interesting... could you give me some additional information on this solution?
I found the PS_ON pin, but what configuration could I use men config.g?

Correct, I try this evening...

You can switch the pin with M80/M81.
Check the option for M81 maybe it is useful in your case.

In RRF3 "pson" is available as a pin name for the 6HC . So configurable with M950.
But for the other boards the pin is not listed here.
I would have expected that this is uniform in RRF3, maybe @dc42 can confirm that.
I can't get why for those boards PS-ON is hard wired in the firmware.

dc42

@gianluca that relay should work if you connect the relay connection labelled +5V to +5V on the Duet, instead of to +3.3V.

DIY-O-Sphere

@dc42
So the gpio pin is cappable to take 5V?
I thought since the logic runs on 3.3v no higher voltage should be applied. What is the limit?

Edit:
Talking about expansion port....

dc42

@diy-o-sphere said in DUET 2 WIFI, RELAY CONTROL VIA GPIO:

No, it isn't. However, the schematic for that relay module shows that the SIGNAL input is used to feed a transistor and LED, and the 5V input provides the power to the relay, which is switched by the transistor.

DIY-O-Sphere

@dc42
Ok. That makes sense....

I have tryed with:
M950 F4 C"exp.heater7" Q500 in config.g
and M42 P4 S1 to turn ON on console.
But pin 31 (heater7) is always on 0,0Volt.

I also powered the relay at 5v (not at 3.3V as in the picture ) but nothing changes...

Tested, all working good ... thanks.
Now I just have to work the relay with the GPIO on heater7

Gianluca

Note, the solution for correct run of relay is:
M950 F4 C"exp.heater7" Q500 (create a fan4)
M4106 P4 S1 (to turn ON the fan or relay).
