I/O
Modules
The field side supply voltage of 24V for the input module is derived from
adjacent I/O modules or from a supply module
.
The supply voltage for the
field side is made automatically through the individual I/O modules by means
of power jumper contacts.
Warning
The maximum current of the internal power jumper contacts is 10 A. When
configuring the system it is important not to exceed the maximum/sum
current. However, if such a case should occur, another supply module must be
added.
The digital input module 750-424 can be used with all couplers/controllers of
the WAGO-I/O-SYSTEM 750.
