Two unique uses for the AAR that may solve a problem for you.
Problem: From one analog signal I want to turn ON a load when the analog signal increases to a certain value, and if it continues to increase, OFF again.
Solution:
- Set R1 to turn ON at (?) 6 mA.
- Set R2 to turn OFF at (?) 10 mA
As the signal input to the AAR increases to 6 mA the load will turn ON. As the signal input to the AAR continues to increase to 10 mA, the load will turn OFF.
Problem: From one analog signal I want to turn a motor ON at low speed when the signal increases to a certain value, and to high speed if the signal continues to increase above a certain value.
Solution:
- Set R1 to turn ON at (?) 6 mA.
- Set R2 to turn ON at (?) 10 mA
When relays R1 and R2 are off, High and Low speed are OFF.
When relay R1 is energized, Low speed is ON.
When relays R1 and R2 are ON, High speed is ON, Low speed is OFF.
