Relay selection - igurgo - 10-06-2023
Slim relay mounted screw socket with LED and protection circuit, as this:

Why doesn't it work with A64?
What compact relays can be used for switching the 220V load with A64?

i think it's ok, but the PDF file not clearly to see the relay's coin voltage.
if relay's coin use by DC12v or 24v, it's ok for A64 board.

24v. But it don't work.

if use 24v relay, let your A64 board and Vin terminal all connect with 24v dc power supply.

The voltage of the digital output without load is 22.4V.
When the relay is connected, the voltage is 8v.
If you pull the SSR out of the relay, the voltage is 12.7V.
At the same time, with a load, the LED of the digital output always lights up, and the relay does not click.
Separately, the relay works if the voltage is supplied directly from the same power supply (24v, 4A).

take a photo how you wire your A64 board.

can you change another power supply for a test? not use LED power supply.

I don't have another 24V power supply yet.
But there is a 12V power supply that was included with the A64 (model YU1202 - 12V, 2A).
If it is connected to my circuit, then the indicators are as follows:
The voltage of the digital output without load is 11.0V.
When the relay is connected, the voltage is 4.3V.
If you pull the SSR out of the relay, the voltage is 6.7V.
In any case, the voltage goes somewhere.
I tried several relays, I have a lot of them.

we will buy your relay for a test with A64 board.
