3.3.4 Overview of the terminal assignment
This overview indicates which system parts can be connected for all
terminals in the module. Depending on the system, one of the
components can be connected to the terminal (e.g. “VR2” or “PR2” to the
terminal “VR2”). Depending on what the module is used for,
simultaneous connection of a number of components may be required,
or may need to be excluded.

1) Terminal assignment on extra-low voltage side: 1, 2 – On/Off (max. 24 V);
3 – earth; 4 – 0-10 V signal
2) Terminal assignment: 1 - earth; 2 - pulse width modulation/0-10 V output;
3 - pulse width modulation input
3) Note with diverter valve: terminal 43 acts in direction of buffer cylinder
