signals - Powering low-voltages devices using CompactRIO modules and builtin pull-up/down resistors -


i have compact rio 9076 4 different modules: ni-9205 (analog input), ni-9264(analog output), ni-9402 (bidirectional digital i/o), ni-9403 (bidirectional digital i/o). have several 3rd party sensors: sensirion sfm3000 (mass flow sensor) 5v , first-sensor hdi0611arz8p5 (pressure sensor) 5v, oval rv21 (reed magnetic proximity sensor) 10v , humidity sensor 5v.

i wish power them using moudules output. of them require 5v , 1 require 10v. can modules?

for of sensor require communicate using i2c protocol require in/out port , pull-up ressistor. modules include pull-up ressistor inside? referance voltage them? , how should enable it?

also oval rv21 (reed magnetic proximity sensor) require pull-down ressitor, modules include pull-down ressistor inside? referance voltage them? , how should enable it?

in general, possible power sensors using ao ni-9264 since acts floating voltage supply. can out put voltage in ranges specifies however, should consider fact output current of module (current drive) 16mv. if enough sensors, should ok.

unfortunately, none of modules mentioned have pull-up resistor.

the ni-9403 has pull-down resistor on channels , reference voltage 0.8v. can see specification of module in attached link.
