Connection
D
Polarity reversal of the 24 V power supply along with a simultaneous
short-circuit on one of the outputs will destroy the module.
D
Polarity reversal of the 24 V power supply along with the connection of
diode-type fuses with rated voltages below 30 V may destroy the module.
Connection via push-lock terminals:

The output modules require an external 24 V power supply. Groups of 4, 8, or
16 outputs share a common 24 V and 0 V potential. This makes it possible to
feed power to blocks of outputs from separate power supply modules.
Thanks to the low leakage current of 0.5 A, the output can be connected to a
Type 1 or Type 2 input conforming to EN 61131-2.
Inductive load at output
Inductive loads such as solenoid valves or contactors must be provided with
a damping network directly at the load. Otherwise, any interruption in the line
interconnecting an output with an inductive load will generate a high level of
interference. In disfavourable circumstances this disturbance may lead to
system malfunctions.
A damping network must be present especially in cases where a switch is
connected in series with the inductive load (safety interlock).
.
All commercially available damping networks may be utilized.
