3-point Differential Regulator RR3P, RR3PT RR3P and RR3PT are two relay modules serving to control of valve or damper actuators with feedback signal 0 - 10V. The system aims to make a difference between the preset and the feedback voltage was equal to 0V. To meet this condition appropriate contacts of the S1 or the S2 are shorted. ![]() Price: 61.8 €
