Is there a way a certain current can be set for one of the outputs?


I need to trigger a solenoid and this requires a current of around 0.8A, I'm using Matlab to control the outputs from LabJack.

The short answer is no, you cannot directly control a solenoid that requires that much current.  The highest current a LabJack U3/U6/UE9/T7 can provide (without an expansion board) is 0.02A(20mA), by using the DAC0/DAC1 analog outputs. 


Remember that the LabJack U3/U6/UE9/T7 is powered by the USB port, and most USB ports can't even provide 0.8A, they usually max out at about 0.3-0.5A.


If you need to control a large current, you should look at the PS12DC power switching board, or an RB12 Relay Board, and associated modules.  Both of these solutions require an external power supply, since USB power is not enough.
