Using the CI-6500 interface to measure over the 10 V limit
To measure up to 30 V on the analog input, use a limiting circuit to prevent the box itself from actually seeing over 10 V. Use Zener diodes and a resistor to create a Zener voltage divider. The readings at the box will be proportional to the input voltage up to ~ 9.3 V.
