Hi
I'm using a CompactRIO to monitor some sensors of temperature and pressure.
Now I need to control a pump and some fans.
After my testing, the pump works from 10V(0%) to 24V(100%), and the fans works from 0V(0%) to 12V(0%).
As a result, I wonder if I need an analog output module to control these devices.
However all the C-series modules seems not to be applicable for my case.
Could someone give me any suggestion how to control these kind of devices?

The thing is called an amplifier.
Some fans accept a PWM as an control input, same with the certain pumps.
Since it's a common task to control such units with 'standard' output (PWM, 20mA,10V) ask the vendor or the devices what amplifier they recommend.

Hi Henrik Volkers,
Thanks to your reply, but my pump and fans are not controlled by PWM and they vary with the voltage amplitude.
I wonder if I should find some programmable power supply to control them ~~
