Description    
The model A-AI-2 attachable indicator is the ideal solution for an on-site   display with additional switching functionality for simple signalling or control   processes.  
With its simple mounting and open programmability via the easily accessible   push-buttons, it can also be retrofitted quickly to a pressure transmitter which   is already operating.  
The display is loop-powered, and so no additional power supply is   needed.  
The 7 mm high LED display ensures good readability, even in poor   lighting conditions.  
The display settings and the functions of the switch contacts  
are set via   a logically-structured menu. With the assistance of two activatable filters,   short spikes can be suppressed and  
thus the display and the switch response   damped.  
The switch contacts feature open collector outputs that can be used for both   min/max alarms and for simple on/off control.  
With its robust and compact plastic case, the indicator fulfills the ingress   protection IP 65 and is thus suitable for a wide range of industrial   applications.
