Description

The indicator shows the measured signal on the large, backlit display. A bar graph indicates the value graphically for a quick process overview. An editable plain text field displays further information like engineering unit or TAG. Limit value infringement is also signalized and an open collector can be switched. The indicator is powered directly from the 4...20 mA loop and doesn't need a separate power supply. For applications in hazardous areas the device is available with Ex approvals.

Field of application

Microcontroller controlled process indicator with field housing and illuminated LC display. The measuring range, decimal point and offset of the display can be configured comfortably by means of three keys in the device with the housing open or by means of a PC with the FieldCare PC software.
