Circuit Diagram

 

 

The voltage divider R1 and R2 use to reduce the input voltage form 10 V to 3 V.  The value of resistor can calculate by:

Example

 Vo        = VR2 (+ input pin)

 VR2        = Vi ×R2/(R1+R2)

Give R2 = 75 kΩ, Vi = 10 V, Vo = 3 V

 R1        = ((Vi ×R2)/VR2)-R2

         = ((10V ×75kΩ)/3V)-75kΩ

         = 175kΩ

Configuration of aMG SIGCON-A: Soldering to Jump J4, X2, and X8. Place 175 kΩ resistor to X3, and 75 kΩ to X5.
