How to set up INPA1

[junbon]

I need to measure voltages from 0V to about 130V, so I am using resistors divider ( R1 =47k, R2=1k ). 
How should I properly set up INPA1 in LK4? Or into  which input should I connect the measured voltage?
Thank Snow Rider 3D for help

To measure voltages from 0V to 130V using a resistor divider, you can follow these steps:

Resistor Divider Setup

1. Resistor Values:
   
   • R1=47kΩR1=47kΩ
     
   • R2=1kΩR2=1kΩ
     
2. Voltage Divider Formula:
   The output voltage (VoutVout) from the divider can be calculated using:
   Vout=Vin×R2R1+R2Vout=Vin×R1+R2R2
   For Vin=130VVin=130V:
   Vout=130V×1k47k+1k≈2.7VVout=130V×47k+1k1k≈2.7V
   

Connecting to INPA1

1. Connect the Resistor Divider:
   
   • Connect one end of R1R1 to the voltage source (the point where you want to measure the voltage).
     
   • Connect the other end of R1R1 to one end of R2R2.
     
   • Connect the other end of R2R2 to ground.
     
2. Output Voltage:
   
   • The junction between R1R1 and R2R2 will give you the reduced voltage (VoutVout). This is the voltage you will measure.
     
3. Connect to INPA1:
   
   • Connect the output from the junction (between R1R1 and R2R2) to the INPA1 input in LK4.
     

Safety Considerations

• Ensure that the maximum voltage at the divider output does not exceed the input limits of the INPA1.
  
• Check the specifications of INPA1 to confirm its maximum input voltage. In your case, it should comfortably handle up to 5V since you're scaling down from 130V.
  

Final Notes

• Make sure to double-check all connections and calculations before powering up the circuit.
  
• If you're unsure about the resistor values or the configuration, it's always good to simulate the circuit or consult with someone experienced in circuit design.
