2.2 Device description
This 2-wire device can be connected to digital SMARTPAT sensors. Without additional
accessories, the calibration and configuration of the sensors can be performed directly at the
application. The two free programmable relays and the second current output allow process
control. Different customer specific measurement pages with up to 4 displayed values enable a
detailed monitoring of the process. By using the second current output it is possible to use the
backlight and high brightness LEDs for NAMUR NE 107 status signalisation.
