- Digital electronic control unit for closed- and open-loop control of single or double solenoid proportional valves with positional feedback control – Eurocard type
- The unit is suitable for control of various proportional valves as directional, flow, pressure and servo valves and regulates feed back from various process values
- The unit controls the position of the valve spool according to the reference input signal ensuring linear regulation with minimum hysteresis
- The unit supplies a variable current proportional to the input reference signal and independently of temperature variations or load impedence
- The PWM stage on the solenoid power supply reduces valve hysteresis thus optimising control precision
- Large, easy-to-use adjustments and readout 4-digit 7-segment LED display to indicate card functions and potentiometers to optimize control
- The unit is suitable for management of various process values as“fast-slow” work cycles, P/Q, pressure cascade controls
- Flexible and reliable system using a 16 Bit microcontroller with high power reserve
- Highly flexible settings with the help of the intergrated software. Assured safety through the use of a hardware watch-dog and reset module
- Error resistant unit – signals do not degrade because they are transmitted or stored with integrated error-correcting algorithms if corruption does occur
- Variable settings for various solenoid systems and sensor signals providing a high degree of flexibility
- Easy software update by use of a Flash-EPROM. Adaptations and extensions can be made without change to EPROM (download from PC via RS232)
