3 Functions and features
The unit monitors the system temperature in machinery and plants�
4 Function
• The unit displays the current system temperature�
• It features an IO-Link interface and is designed for full bidirectional communi-
cation�
• The unit generates 2 output signals according to the parameter setting:
OUT1/IO-Link:
-Switching signal, limit values for temperature
OUT2: 2 selection options
-Switching signal, limit values for temperature
-Analogue signal for temperature
4.1 Switching function
OUTx changes its switching status if it is above or below the set switching limits�
Hysteresis or window function can be selected�
