K Series Hydraulic/Pneumatic Valve Controller System

VALVE-CONTROLLER-SYSTEM

Roll over image to zoom in

This valve controller system uses the SB0800 octal valve controller IC with an MCU and two power MOSFETs. The system can drive proportional and digital valves, as well as the system pump. Monitoring and protection features protect the system from hazardous events such as short circuit, over current or voltage and other abnormal conditions.
