I've been trying to drive a 12V inkjet valve (specs)with a 5V digital output from a National Instruments controller (PCI-7334). I'm using a Radio Shack 13.8VDC 3A power supply to power the injet head. Based off the numbers I have of the injet valve, I've picked this NPN transistor.
I tried...
I'm trying to drive a 12V valve with a TTL signal from my motion controller. After various suggestions, I'm trying a mosfet to drive the circuit. Specifically, I am using this mosfet: http://www.digikey.com/scripts/DkSearch/dksus.dll?Detail?Ref=60832&Row=533489&Site=US
I have the TTL connected...
Before I begin, I am completely out of my element in this project, so my apologies if I don't use correct terminology.
I am trying to control a microliter dispensing valve using a relay control circuit. This circuit needs to be fast, as I need the droplet sizes to be very small. My digital IO...
