I am trying to solve a simple question (I think). I found this circuit board and I was wondering if I could use it as a power circuit :
My idea is to connect the arduino outputs to the gates of the mosfets, letting the current flow through some solenoids, motors, fluorescent tube.
The thing is I am not familiar with PLC circuits at all and would need some advice. It seems a bit more tricky than I expected. Also I would need to choose between PNP and NPN input. I beed to be able to control this via PWM also...
I hope someone will be able to help.
Cheers.
There's a mistake in the specifications but I don't think it's fatal. It says the "output contacts" are 5A 250V but that would only be true if you were using this board to drive a 5A 250V relay.
I don't see where you choose PNP or NPN input. It probably doesn't matter. A 5V Arduino will probably drive this just fine with either option.
The 5KHz "switching frequency" indicates that it will work with PWM just fine.
