The PROP CAN valve con­troller with CAN bus reg­u­lates the flow rate of a pro­por­tional valve. It can be used in many hy­draulic ap­pli­ca­tions. CAN high speed can be used to com­mu­ni­cate with other mod­ules and sup­ports easy in­te­gra­tion into ex­ist­ing sys­tems. The microcontroller-based current control allows the desired output current to be specified using application software.

Con­trol and data down­load via CAN bus in­ter­face is sup­ported. Sup­ply volt­age and tem­per­a­ture fluc­tu­a­tions are com­pen­sated which en­sures con­stant flow rates. To coun­ter­act stic­tion and hys­tere­sis ef­fects a dither fre­quency can be ad­justed (su­per­im­posed small rec­tan­gu­lar rip­ple fre­quency). Please refer to the sec­tion hous­ings and base plates for ad­di­tional hous­ing op­tions.
