24 V power supply
I/O units are supplied with 24 V power from the connector XT31 (see previous
illustration).
Parallel connection
The 24V coming from DSQC 662, terminal XT31.1, can not be increased by adding
power from any other 24 V power supply (not even DSQC 609). There is no load
levelling function that ensures current distribution. The unit will not be destroyed
but the lifetime may be affected.
The parallel connection of two DSQC 609 is permitted (factory setting) but not more
than two.
