The internal outputs are protected by a so-called multifuseTM. In contrast to a safety
fuse, this kind of fuse will independently cut in again in the case of an overload after
a certain period (thermal time constant), i.e. the impedance becomes very low again.

X 4-pole Mini CombiCon (PHOENIX)
Using the internal 24 V supply
The CNC module generates an internal voltage of 24 V which can be used for small
loads (max. 350 mA).
Using an external supply
1 Apply a voltage of 24 V to pin 23 and pin 24 by connecting an external power
supply. Pin 22 must not be used/assigned.
A diagram showing the wiring of the 24 V (internal/external) can be found in the chap-
ter "Wiring of 24 V (internal/external)“, page 53.
