Hi,
I want to control two 24VDC 3/2 way solenoid valve using the USB 6008 DAQcard. Now from previous posts and NI examples I have understood that I need a solid state relay than can switch with a 5mA signal from USB 6008 and then using a 24V DC power supply can energize the solenoid valve. Now what I am unable to understand due to my lack of knowledge of electronic devices as to what choices to make for these equipments i.e. solid state relay (amperage and other ratings), power supply(amperage rating choice). I apologize if there is any lack of information. I was also told that the current rating for the solenoid would also be a deciding parameter ( I am unsure of that as well). Any help is more than welcome.
