Hello, I just received a 16 Channel Mini-Relay Module (Model: BK_RL16_01).
I’ve been trying to just get the thing to power up. I imagine I could simply control it using a High and Low signal after that.
Although I’m not sure what to do with the VCC and GND pins. Another thing that sort of gets me is how this board has three pins for each relay. I’m thinking that
perhaps one of them just isn’t used. I found some [instructions (aliexpress.com/item/16Channe … 11119.html)) although they don’t make much sense to me. If someone could point me in the right direction it’d be greatly appreciated as I’ve tried a couple times to get it to work and ended up tripping off my surge protector in one of my attempts so I don’t wanna fry the board before I get a chance to use it.
Below seems to be a so-so schematic of what was found googling for BK_RL16_01. Single pole double throw (SPDT) relays provide for having either open or closed contact states.
