Intended Use

The ProLine P 44000 Pt100 transmitters isolate and convert the signal
of a Pt100 resistive sensor into a 4 to 20 mA current signal. They are
designed specifically for applications with high working voltages
which require high insulation strength to protect parts of the installa-
tion and where the insulation of the resistive sensor is not sufficient.
The devices have a broad-range power supply 22 ... 230 V AC/DC
± 10 % and galvanic 3-port isolation.

WARNING!
For applications with high working voltages, take measures
to prevent accidental contact and make sure that there is
sufficient distance or insulation between adjacent devices.
