Hi! I am currently using DAQ Card 6062E for data acquisition and in the catalogue it says that it accepts +/-10V for both input and output. But in the pinout diagram, I could find only +5V output. So, I would like to know if that is for illustration purpose only or is it really 5V. My sensor needs a power supply of 9-30V DC, so I'm a little worried. Kindly let me know your suggestions, please. Thanks in advance! 🙂

Read the SPEC! 5V+ is the only power you can directly use for sensor supply .. max. current READ SPEC... (5to10 or +-15V DC/DC supplies exists ... look for a low noise one)
Or choose an external powersupply..
If you want to (ab)use the AO 10V to power your sensor: READ both SPECs !
NI AOs usually don't provide more than 2mA current.

Hi, sorry I couldn't find the details mentioned in the manual given. I found just one manual from the NI website and there was no mention of this information. 😞 My sensor consumes less than 60mA, so it should be okay if I wire the supply to AO 10V and AO GND I guess? Can you kindly tell me what the both SPECs are, please?
Thank you.

Hi, sorry I got the manual fortunately! Thank you very much for the suggestion. Regarding my previous query, I guess the 2mA current should be okay? Also, I can use the AO as a power supply for the sensor?
Thank you!

SPEC mean the specification documentation usually found in the manual´/documentation of the device..
G**Gle is your friend 😉
Yeah, it's all buried in the fineprint 😄
And have you read my warning about the AO ?

Haha, yes of course. I read your note about AO and also the manual of 6062E. I saw that AO gives 5mA at 10V, which is okay I guess, since my sensor datasheet tells me that it would consume <60mA.
Spotreba in Czech means consumption and the red part above is the input voltage. 😉

59mA is <60mA but >5mA!!

**bleep**! I look like a fool now xD. Thanks for the conceptual lecture! 🙂 I got the point. Thank you very much!
