NI9472 giving an output of 12V instead of 24V to activate solenoid

[Miller34]

I'm using a cDAG-9188 with a NI9472 connected to it, to activate a solenoid of 24V.

I've connected 24 +VDC to Vsup and the - to COM.

The output that i get is 12VDC instead of the 24VDC that I need.

Can someone maybe help me to solve this issue?

How much current does your solenoid need to activate?  Can your power supply handle that much current?  How do you have the solenoid hooked up?

[Miller34]

There are 2 different DACQ systems,  1 with a solenoid of 16W (0.67A) and another one with 22W (0.91A).

The connection is based on attached picture.

I've tested the output with NI-DAQmx by putting the output from 0 to 1.

When I do this, the signal that comes out of the DAQ gives 24V.

But when I use labview it only gives 12V.

So i think this is a software instead of hardware issue.

Is there maybe a way to adapt the voltage of the outputs in labiew?

The digital outputs are literally just relays to connect your power source to the output.  So the only voltage control is the power supply.  Are you controlling the power supply with your code as well?

[Miller34]

No there is no control on the power supply in the code.

Hi Miller34,

Are you able to upload your code and/or screenshots? How are you reading the 12V reading is it on an external piece of hardware or is it in software? 

Are you able to provide any more details about your set up?

Many thanks

I will try to upload some screenshots today.

I am reading it with a multimeter over the connection. So on the hardware, not the software.

The logic of the system is that when the solenoid is powered a feedback signal gets send to the DAQ via a TRIAC and then it reads out some sensor values.

So the "24VDC signal"  from the output is going in paralllel to the solenoid and to the TRIAC.
