I am using a NI USB-6009 to control a relay which is used for controlling a 24V Solenoid Valve. The relay control voltage is 4-28V and therefore the 5V output should be enough for it. Once I energize the pins, I can get a differential voltage of 5V, but when I connect the relay to the same pins, the voltage drops to 3.3V which is not enough for the relay. I assume it has something to do with the relay requiring a current more than what the DAQ can provide. Is there any way to fix this? Like any suggestions for a relay that can be controlled by USB-6009 and yet be able to control a 24V valve? (I am using another power supply for the valve so I just need the DAQ to support the relay.)
