Hi Team,
Do we have an evaluation module or reference design of a controller that we can interface to the dosing pump below.

The pump's requirements are as follows;
To operate the P4.1S pump under constant pressure, external control of the pump is required. The pressure can be read out via the analog out of the pump using an A/D converter. With an appropriate software environment (e.g. LabVIEW or Python), a control algorithm has to be established. The control algorithm will then adjust the flowrate of the pump, which is transmitted via a D/A converter to the analog input of the pump. The voltage range of the pressure out is 0 – 1 V (400 bar corresponds to approx.. 400 mV – calibration with the displayed pressure is recommended). The voltage range of the flowrate setpoint is 0 – 10 V (10V = 10 ml/min).
Regards,
Danilo
