4.2 Connection of the sensor/signal conditioning
instrument
VEGACONNECT 4 can be connected to virtually all communication-
capable VEGA instruments. With instruments of the plics
®
series it
can be mounted directly into the sensor. In this case, you can remove
VEGACONNECT 4 out of the connection box and insert it into the
plics
®
device instead of the indicating and adjustment module.

In hazardous Ex areas, the HART or I²C cable of VEGACONNECT 4
can be connected to an Ex approved sensor. VEGACONNECT 4 and
the PC must not be located in Ex area.
VEGACONNECT 4 can be connected to the I²C bus interface of the
following sensors.
•
all sensors of plics
