The valve terminal type 8653 AirLINE Field was specially developed for the requirements of process automation. This means that new diagnostic functions can be displayed on the LC display 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 provides a quick overview of the system status. The hardware design is optimized for mounting close to the actuator. An intelligent mounting system offers the possibility of mounting in a wide variety of positions. But of course, simple installation 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.
