1.2 Brief description
The transmitters record sensor signals from RTD temperature probes, thermocouples, resis-
tance transmitters, or resistances/potentiometers. When using a resistance/potentiometer or
RTD temperature probe, the sensor on the input side can be connected with a 2-wire, 3-wire,
or 4-wire circuit. Voltage signals in the range from -100 to +1100 mV can be recorded in the
same way. Depending on the selected measuring input, the linear and temperature-linear lin-
earization variants and the possibility of easily configurable customer specific linearization are
available.
Type 707050 delivers 4 to 20 mA as an output signal. Type 707051 delivers 4 to 20 mA or 0 to
10 V as an output signal. The measuring input and the output signal are electrically isolated
from one another. It is possible to reverse the output signal in both types.
The transmitter configuration with respect to probe type, probe connection technology, measur-
ing range (freely configurable), and linearization is carried out by means of a setup program on
the PC. The connection to the PC is established via a USB interface which does not require
additional auxiliary voltage. Via the USB interface, the min./max. process value and the min./
max. operating temperature recorded by the transmitter can be read and the sensor wiring can
be checked online.
The operating status of the transmitter is indicated by a two-color control LED (red/green). This
is lit green during fault-free operation. A fault such as a probe break will be shown by the cor-
responding LED indication.
