voltage for
PLC outputs
10 – 108
Permissible load: Resistive load (inductive load only with quenching diode parallel to
inductivity)
MC 42x(B), PL 4xxB: Short circuiting of one output is permissible.
No more than one output may be short-circuited at one time.
PLD 16-8: The outputs are short-circuit proof.
Note
The switching outputs need a minimum load of 5 mA.
They conform to EN 61131-2.
DANGER
PLC outputs must neither be connected to a 24-V supply, nor to other PLC outputs with a
difference in potential. Otherwise, the voltage present at the PLC outputs is transmitted to
the power supply. As a result, the PLC outputs that can be switched off may nevertheless
be supplied with this voltage.
This could lead to damage or injury to property or persons!

Note
The transmission of output states of handwheels and PLC input/output units (expansion
cards) is performed with HEIDENHAIN serial data transmission busses on the connectors
X23 und X47.
On the X41 and X46 connectors, each output has its own wire.
