kyThinkTop® BasicAlfa Laval ThinkTop® Basic AS-Interface 62 node

.

ConceptThe ThinkTop Basic is designed to ensure optimum valve control inconjunction with Alfa Laval butterfly, single-seat and Mixproof valvesand it is compatible with all major PLC systems (Programmable LogicController) with a digital PNP/NPN interface. It is for use in food, dairyand brewery installations and in biopharmaceutical applications. TheThinkTop Basic fits all air operated valves from Alfa Laval

Working principleThe ThinkTop Basic is a basic control head including sensor boardand solenoid valves to control processing valves. It is used to controland supervise pneumatic valves and is mounted on top of the valve.It receives signals from a PLC to control the solenoid valve and itsends the valve status feedback signals back to the PLC. To adapt thesensor board to the specific valve, the users make a simple set-upby using local keys.
