Using NI 9403 as voltage source for its own inputs

[OrHirshfeld-SK]

Hello all

I know it few years old topic but i have similar problem

I have Compact RIO 9076 with 4 different modules: ni-9205 (Analog Input), ni-9264(Analog Output), ni-9402 (Bidirectional Digital I/O), ni-9403 (Bidirectional Digital I/O).

I have several 3rd party sensors: sensirion SFM3000 (mass flow sensor) 5v , First-Sensor hdi0611arz8p5 (pressure sensor) 5v, OVAL RV21 (Reed magnetic proximity sensor) 10v and another humidity sensor 5v.

i wish to power them using moudules output. most of them require 5v and the one require 10v. can i do it with my modules?

for some of the sensor i require to communicate using i2c protocol which require in/out port and pull-up ressistor.

is the modules include pull-up ressistor inside? what is the referance voltage for them? and how i should enable it?

Also the OVAL RV21 (Reed magnetic proximity sensor) require pull-down ressitor, is the modules include pull-down ressistor inside? what is the referance voltage for them? and how i should enable it?

Thank You
