Hello,
I need to control a DC Motor, so I’m interested in the K8055 USB board. I’m just still not sure whether this card meets the conditions.
So firstly, I would like to know, how the PWM-port of the K8055 board is working:
Which frequencies and which voltage amplitudes can be generated?
How much power and current can be applicated out of this port?
Also, generally, is it possible to raise the voltage of the PWM and the analog ports at a level of 10V by linking the board to a second additional power supply? Or anyhow else?
Could you please send me the technical data and the circuit plan of this board?
And is it possible to gain control over the board by Labview programming?
Best regards,
Edgar Brauer
The PWM output is an open collector NPN transistor output.
[quote]Which frequencies and which voltage amplitudes can be generated?[/quote]The PWM frequency is fixed 23.43kHz. Maximum voltage is 40V.
[quote]How much power and current can be applicated out of this port?[/quote]max 100mA
[quote]Also, generally, is it possible to raise the voltage of the PWM and the analog ports at a level of 10V by linking the board to a second additional power supply?[/quote]Yes up to 40V external power supply can be used.

Yes, seems to be possible. On the downloads page there is 3rd. party, National Instruments Labview driver for the K8055 board.

- Also Google gives quite many results with the words K8055 and Labview.
e.g. these:
