Hello! I have this USB-6000 unit which has only 3.3V 4mA digital output. I want to switch a relay by means of MOSFET but so fat the current/voltage capabilities has had no success. I am easily able to it it using any Arduino wiht 5V 20mA out though. Probably lower threshold gate voltage FET would help?Could anyone advise? Except,of course getting a better DAQ.
Thanks!
