Display Elements - WAGO 750 Series Manual

The operational readiness and the trouble-free internal data bus
communication of the channels are indicated via a green function LED.
An optocoupler is used for electrical isolation between the bus and the field
side.
The field side supply voltage of 24 V for the output 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.
Note
Use an appropriate supply module (e.g. 750-602) if an electrically isolated
voltage supply is required!
The specialty module 750-511 and its variations can be used with all
couplers/controllers of the WAGO-I/O-SYSTEM 750 (except for the economy
types 750-320, -323, -324 and -327).
This description is valid for the XXXX3A04... hardware and software
versions. The version is specified in the manufacturing number, which is part
of the lateral marking on the module.
