Does the RevPi support flowmeter sampling and Peak hold output control?

Purecade · Post by **Purecade** » 17 May 2022, 11:16

Hello,

I would like to know if the Industrial Raspberry Pi supports flow meter input sampling：Voc（3.2-3.4V），Vin（12V），If（1.5kHz）,Tua_in(10us)
Does the RevPi support output peak hold to drive the solenoid valve that controls the hydrogen injection? Peak：4A/1ms(Current)；Hoid：0.8/0~40/ms(Current).

Best regards,
Cade

Hello,
We have DO and AIO module that we can recommand for your Task but: DO (Digital Output) can only supply 500mA and not the required 800mA
AIO ( Analog Input /ouput modul) input conversion time >= 8ms → too slow

I want to go a little further in your request to help you.
What do you want to do in general?
Which flow meter are you using?
