This module is used to control the slide position in proportional valves with electrical feedback. Various setting parameters enable optimal adaptation to the respective valve. The control circuit works with a control cycle time of 1 ms and the integrated power output stage with a cycle time of 0.125 ms for the solenoid current control. The setpoint and the actual value are read in via freely scalable analog inputs (range 0… 10V or -10V…10V or 4… 20mA). The output current is regulated and therefore independent of the supply voltage and the solenoid resistance. The output stage is monitored for cable breakage and switches off the output stage in the event of a fault. The operation is simple and problem-oriented, which ensures a very short training period.
