3 About ThinkTop
ThinkTop V20 is a valve-top surveillance unit that provides surveillance of valves during the fluid
handling process. The surveillance unit has been developed with user friendliness and robustness in
mind.
ThinkTop V20 comes with a valve surveillance 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, and IO-Link.
The ThinkTop V20 detects valve position 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.
V20, V50 and V70 series
ThinkTop comes in three series: V20, V50 and V70. The V20 series is the option for when all you
need is sensing. 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.
