Dear sir,
Actually i want to develop an ANALOG IO CONTROLLER in the devicenet
netork.I am using 4 analog input and 4 analog out put channels with
120v ac as input , i am stepping down this voltage to 3.3v that can
be given as an input for my A/D converter inside my controller.Does
the analog voltage 120vac needs to step down to the required operating
voltage of the analog pins inside my controller or else do i need to
calculate the exact voltage between 0 to 120vac in this ANALOG IO
CONTROLLER modules that can be fed as input to the controller analog
pins. Can you please explain me how an analog i/o controller works
with respect to 0 to 120 vac input voltage in the device network.
With Regards,
Vasu
