Display Elements

The field side supply voltage of 24 V for the counter 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.
Attention
This module has no power contacts for receiving and transmitting the ground
(earth) potential. A supply module is required, if the adjacent modules need
to be connected to the ground.
Note
Use an appropriate supply module (e.g. 750-602) if an electrically isolated
voltage supply is required!
The module 750-404/000-001 can be used with all couplers/controllers of the
WAGO-I/O-SYSTEM 750 (except for the economy types 750-320, 750-323,
750-324 and 750-327 and the ModBus controllers 750-812, 750-812/025-000
and 750-814).
