Note!
To ensure the highest level of accuracy, we recommend using the RTD 4-wire connection, as this
compensates for measurement inaccuracies caused by the mounting location of the sensors or the
line length of the connecting cables.

Outputs
4.4.1
Analog output
This output can be used either as a 0/4 to 20 mA current output or as a voltage pulse output. The
output is galvanically isolated. For the terminal assignment, refer to
15.
4.4.2
Pulse output
Active voltage pulses are output at the pulse output.
Voltage level:
• 0 to 2 V corresponds to Low level
• 15 to 20 V corresponds to High level
Maximum output current: 22 mA
4.4.3
Open collector output
The two digital outputs can be used as status or pulse outputs. Make the selection in the following
