4 channel PWM timer/counter needed

[mogensen]

Hi,

Can anyone suggest a counter/timer to use as a 4 channel PWM driver? I've got a standalone platform with 4 fluid pumps that I need to control independently via LabVIEW. I need to run it in the field so I cannot use a PCI card and the form factor is important so the PWM-520 module is too big.
I need to run around 4kHz - 20 kHz.

Any suggestions?

Thanks,

Claus Mogensen

Hello Claus,

Since you're not able to use a PCI card or Compact FieldPoint it would be helpful to gather more information about your application before making a product recommendation.

1.  What dimensions are acceptable for your application?

2.  Do you intend to use these PWM signals as current drivers?  If so how much current do you need the device to provide?

3.  What form factors are acceptable?

4.  What is your controller?

5.  Will this setup be deployed in a harsh operating environment?  (Excessive shock/vibration, high temperatures, etc.)  If so what parameters must it withstand?

 

The above questions will help narrow down possible solutions, but if you have any other information about your application please feel free to include it as it will only allow for a better recommendation.

Cheers,
