Display Elements - WAGO I/O-SYSTEM 750-478 Manual

8 • 750-478 [2 AI DC 0-10 V, Single-Ended]

Display Elements

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 analog input module 750-478 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).
