I'm using MIDI triggered solenoids to make a percussion robot.
I have a larger 12vdc 8a solenoid that I want to use. I had an earlier setup with an Arduino Leonardo card. With that, in order to power that solenoid I used an IRF520 Mosfet module (please see attached pic) with a 12v 10a power supply.
Now instead of an Arduino I am making a system with a card called MIDi Switcher shown here: https://six4pix.net/product/midiswitcher/
The card can handle eight solenoids but has an 8a maximum, so if I use the card as is I can only hook up 1 solenoid, so I'd like to use an external mosfet with an external power supply like i did with the Arduino setup.
The manufacturer of the MIDI Switcher states:
The MIDI switcher outputs are “open drain” so when they are “on” they provide a path to ground. This means the screw terminals on the MIDI switcher could switch an external PNP transistor or P-MOSFET (these are switched “on” when their base/gate is “pulled down”) but the could not switch an NPN or N-MOSFET (switched when their base/gate is “switched on”)
From what I can tell, the IRF520 module I have is NPN so is the wrong type. Please correct me if that isn't right.
Is there a similar module that I can use for this? I like having a module that has the screw terminals, it makes for easy hookup.
I might also mention that it could be that my total amperage is below 8a so I don't need to even use an external mosfet. But I would feel safer using an external module. The Midi Switcher card runs on 12vdc so that would be the voltage it would send out to an external module.
