I want to light a bulb connected to the socket by using an 1 Channel Optocoupler Relay Module which accepts an input of 5V.
From my understanding, when the modul receives DC current (5V), it's going to turn on the other circuit and turn on the bulb.
I'm not sure how to connect the module in this context.
It looks like this:
+----------------------+ | 10A 250VAC 10 125VAC | DC+ – 10A 30VDC 10 28VAC – NC DC- – – COM IN – – NO | SRD-05VDC-SL-C | +----------------------+
It didn't came with any documentation, so I'm not sure what these notations mean.
I assumed I have to connect the positive wire from the 5V circuit to
DC+ and the negative/ground to the
DC-. I'm not sure if this is correct.
However, I don't understand how to connect the wires at the other end.
I have no ideas what
Is there any place where I can find the documentation for this kind of relay or are these universal notations? What do they mean?
How should I make the connections?
The module looks like this:
So, I connected the bulb wires to
NC and the bulb is turned on when I connect it to the socket. Then I tried connecting a battery to the
DC- and the power led of the relay component is turned on, but the bulb is not turned off.
