Talon SRX also has a single analog input. That might be another way to get the analog voltage into the RIO (over CAN bus). You don't need to use the sensor for closed-looping, you can just use CAN bus to get more analog inputs that way.

The analog in is 3.3V max but with the analog encoder breakout, you can wire a 5V signal (the breakout scales it to 3.3V).

Default update rate is 100ms, but that can be overridden depending on language. Also if you "select" the sensor programmatically, you can get it at 20ms per update.
