can we still use the CPR-360?

As the title says, can we still using this converter http://www.andymark.com/product-p/am-0899.htm ?

If the use is for the radio then there is no need for it since we now have the Voltage regulator module, If it is for something else the voltage regulator module also has an empty port or 2 that has the same effect as the converter.

It's for take the signal of a sensor from 12 VDC to 5 VDC so it can be detected for the roboRIO, so in ths way we don't have to build a costum circuit

Are you not able to use one of the 12v to 5v ports on the VRM?

No, because that for powering, and I want to use the CPR-360 for signal conditioning

Oh, I see , from what I can see there is nothing against using it for custom circuits in updates/ the manual. I would suggest asking in the Q and A to be sure though.

It won't do that very well, if at all.

Based on earlier posts about a 12V sensor, I think the proper solution is a very simple custom circuit: use two resistors to make a voltage divider.

Connect the output of the sensor to one end a 1.5 kilohm resistor. Connect the other end of the 1.5k resistor to the roboRIO's signal input pin, and also to one end of a 1 kilohm resistor. Connect the other end of the 1k resistor to the negative pin on the roboRIO's input. When the sensor supplies 12 volts, the roboRIO will see approximately 4.8 volts.

I know, it's even better a zener regulator, that way I don't lose any current, contrary what could happen with the voltage divider, it's just that talking with the team we want to use all that we have in our hands instead that starting to build stuff, but yeah I will try voltage divider and zener regulator.
