STRUCTURE AND FUNCTION

The control head Type 8681 has been designed for use as an
actuator for pneumatically operated process valves and / or for
recording the switching states of these.
For the recording and feedback of the process valve switching posi-
tions to a higher-level control, the control head has been equipped
with a contact-free position measuring system which operates with
3 discrete, adjustable feedback signals (Teach-In function).
Various pneumatic and electrical connection variants are available.
Positions and status information can be indicated by 3 signal
colours. Further colours are available for the büS/CANopen and
the IO-Link design.
