• The unit features an IO-Link interface�
• The unit is designed for two or three-wire operation� Depending on the operat-
ing mode the following output signals are provided:

2 wires
OUT: analogue signal for temperature measurement /
analogue signal for diagnostics
3 wires
OUT1: switching signal for diagnostics / IO-Link
OUT2: analogue signal for temperature measurement /
analogue signal for diagnostics
5.1 Analogue function
The unit converts the measured temperature value into a temperature-proportional
analogue signal�
In addition the analogue output is used for diagnostics
tion): The transfer of the measured temperature value is interrupted for diagnostic
messages depending on the operating mode and the setting of drEd and an ana-
logue signal according to NE43 of 3�5 mA (FOU2 = On) or 21�5 mA (FOU2 = OFF)
is provided�
Depending on the parameter setting
the analogue signal is within the
measuring range�
4���20 mA with setting [OU2] = I or
20���4 mA with setting [OU2] = Ineg�
The measuring range is scalable:
• [ASP] defines at which measured temperature value the analogue signal is
4 mA (OU2 = I) or 20 mA (OU2 = Ineg)�
• [AEP] defines at which measured temperature value the analogue signal is
20 mA (OU2 = I) or 4 mA (OU2 = Ineg)�
Minimum distance between [ASP] and [AEP] = 5 K�
If the measured temperature value is outside the scaled measuring range, the
analogue signal is 20...20.5 mA or 3.8...4 mA (→ Figure 1). When the measured
