5.1. structure and function
The control head Type 8695 can control single or double-acting process valves.
The control head Type 8695 has been optimized for the integrated modular fitting of series 21xx process valves
(Element) with a 50 mm actuator. Various expansion stages are possible thanks to the modular design.
For installation on the 20xx series (Classic) there is a special model which is described in Chapter "5.1.2".
The valve position is recorded via a contactless, analog sensor element which automatically detects and saves the
valve end positions by means of the teach function during start-up.
Option: Communication possible via AS Interface.
