SYSTEM DESCRIPTION

5.1

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 actuator size ∅ 50. 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 and DeviceNet.
