The Controller has been specifically designed for Hauhinco Control Valves and forms a closed loop circuit with hydraulic valve.
The demand values for the pressure at the working connection or the position of the setting piston are transmitted by the user by scaled voltage (0-10V) and electricity (4-20 mA) to the controller. Through the controller the demand value and the current value are compared and the valve is being calibrated until the offset is minimized. The control parameters can be altered in many areas within the control software. Further functions as for example a ramp function are also implemented. Depending on the used valve type (3/2 or 2/2 way valve) one or two valves can be controlled per one controller. The master/slave configuration of the controller allows an expansion to up to four 3/2 way valves or eight 2/2 way valves that are controlled by the master controller. The previous control cards RE1, RE2 und RE3 can be replaced with the RE4.
