Profibus PA Insights

What is Profibus PA?

PROFIBUS PA (Process Automation) is a fieldbus technology used in process automation. It is designed for intrinsically safe applications in hazardous areas. PROFIBUS PA allows sensors and actuators to be connected to a control system using a two-wire cable, transmitting both power and data. It is commonly used in industries like chemical, pharmaceutical, and oil & gas for applications such as level measurement, pressure measurement, temperature measurement, and valve control.
