Can one use usb 6210 DAQ for controlling a 24V DC solenoid valve? I read "USB-621x digital lines can drive 16 mA for relay and actuator control"
Goal is to digitally control solenoid valve using usb 6210. What would be the wiring diagram to connect 24 V PS, solenoid valve and USB 6210.
Any help would help me figure out. Right now I am not even sure if 16 mA on digital line is compatible with 24VDC 0.55 W solenod valve. If not then can one work with a lower Voltage solenoid valve 12VDC at 0.55 W with USB 6210?
Need to control two valves with the same USB 6210 DAQ and one 24VPS.
Thanks

The 6210 has a 5 volt output. Not 24 or 12 volts.
Thanks.
Which USB DAQ would I need that can supply 24 VDC and also turn on/off two solenoid valves via Labview vi and DAQ.

Hi,
If you add a switch MosFet (or a relay) you can switch your valve with a digital output from a DAQ device.
If you want I can place a little schematic here. But you have to build some hardware to control the valve.

Thanks KC,
Please do illustrate including the reqd hardware.
there are two 24VDC solenoid valves, one usb DAQ 6210 and one 24VDC PS.
Many thanks!

First what is the current rating of your valve ?
In this thread you find a relay driver.
Also you can place the valve in the circuit where the relay coil is. But it depends on the valve current.
