10.1

Function and system design

Electronic monitoring and conversion of input signals in industrial temperature
measurement.
The temperature DIN rail transmitter is a two wire transmitter with an analog output. It
has measurement input for resistance thermometers (RTD) in 2-, 3- or 4-wire
connection, thermocouples and voltage transmitters. Setting up of the unit is done using
the configuration set for PC.
10.2 Input
Temperature (temperature linear transmission behavior), resistance and voltage
The transmitter monitors different measuring ranges depending on the sensor
connection and input signals.
