Functions And Features; Function; 4�1 Switching Function - IFM Electronic efector 600 TN21 Series Operating Instructions Manual

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�
