The valve terminal type 8652 AirLINE was specially developed for the requirements of process automation. The new diagnostic functions on the LC display can be displayed both in plain text and symbolically. This simplifies the assignment of the displayed messages, which saves time during commissioning and maintenance. In addition, a diagnostic message to the control system is possible. This enables a quick overview of the system status. The hardware design is optimized for control cabinet floor mounting. Of course, mounting on the standard rail is also possible. In addition, important pneumatic functions ensure increased process reliability. For example, Check valves in the exhaust air ducts prevent unintentional triggering due to pressure peaks.
