The ThinkTop® Basic is a basic control head including sensor board and solenoid valves to control processing valves. It is used to control and supervise pneumatic valves and is mounted on top of the valve.     These are mid-level units that fulfil basic requirements for the automated control and monitoring of sanitary valves in installations where fewer digital inputs combined with a full range of outputs are involved. They can be applied with traditional digital interface to AS-Interface and intrinsic interface. Installing ThinkTop Basic units is both quick and easy. They are a cost-effective way to achieve a considerable degree of flexibility in controlling both automated and semi-automated processing set-ups. Alfa Laval provides a complete range of valve-top control and monitoring equipment for use with sanitary valves.
