Problem with NI 9411 5VDC output channel

[Mike640]

Hi,

   I am having a problem with the NI 9411 5VDC output channel. According to the module specification, it was stated the module required an external power source of 5-30 VDC. Upon supply the module with the voltage requirement, i am still unable to obtain the output voltage from the output channels. Does that mean the voltage output can only be available depending on the program?

Thanks in advance,

Regards,

Hi Mike,

Thank you for posting on the National Instruments forum.

You should still be able to get an output voltage by correctly powering the NI 9411 and your external device.

If you do not have a 5 V power supply to directly power the external device or if you want to simplify wiring, you can connect an external power supply to the Vsup and COM terminals on the NI 9411 screw-terminal connector, and connect the external device to one of the +5 Vout pins. If the external device is already powered, you do not need to connect a power supply to the NI 9411 or connect the +5 Vout pin to the external device.

Hope this helps.
