2.2.3 Closed loop control: differential pressure with sensor 4…20mA set point via analog input
A constant differential pressure of 4 bar is needed. The 4…20mA differential pressure sensor with a measurement range of 0-6 bar is
connected to analog input 2. The set point is given via analog input 1 by a voltage 0…10V signal. The set point is 4 bar is equivalent to
6,66V (10V/6bar*4bar).
Info: the set point via analog input has a higher priority than the set point via display.
