M
Max. connectable cross-section: 2.5 mm
Type: Screw terminal 2 (see Appendix A)
Note
The two "+" and "M" terminals are jumpered in the connector and not in the unit. This
ensures the supply voltage is looped through.
This power supply is required for the digital inputs/outputs only. The electronics power
supply and the power supply for the analog inputs/outputs are drawn via the option slot of
the Control Unit.
Note
The power supply of the digital inputs/outputs and the electronics power supply of the
Control Unit are isolated.
Note
If a momentary interruption in the voltage occurs in the 24 V supply, the digital outputs will
be deactivated until the interruption has been rectified.
