Power reading converter
Product:
G2BA480V12A 4-20mA
Data sheet:
Task:
The pressure applied by the cleaning brush for cleaning circuit boards should remain as constant as possible to ensure optimal results.
Solution
When the pressure increases, the power drawn by the brush motor also increases. The use of a power measuring transducer forwards the power consumption of the brush motor to the PLC over a standard signal (4–20 mA), and the PLC then adjusts the position of the brush accordingly with an actuator.

Use/value:
- The solution offers the required rapid reaction
- Mechanical solution too expensive and complicated
