2 About ThinkTop
ThinkTop is a valve-top control unit that provides surveillance and control of valves during the fluid
handling process. The control unit has been developed with user friendliness and robustness in mind.
ThinkT
op comes with a valve control sensor board for connection to any PLC system. There are three
types of communication interfaces available:
Digital I/O 24 VDC, AS-Interface v3.0, AS-I v2.11 and IO-link.
When the ThinkTop receives a signal from the PLC system to open the valve, a built-in solenoid valve
shifts the connected valve into position. The position is detected through a sensor target attached to
the valve stem through a touch-free sensor system. The position is then evaluated and if valid, the
corresponding feedback is returned to the automation system via the communication interface.
V50 and V70 series
ThinkTop comes in two series: V50 and V70. The V50 series is the compact option with a feature set
tailored to valves that require only one solenoid valve such as butterfly and single seat valves. The
V70 series is the more flexible option that can be configured to meet the needs of the most
demanding valve applications such as Mixproof valves.
