The I/O module 750-496 (8AI 0/4-20mA S.E.) receives the 24 V voltage supply
for the field level from an upstream I/O module or from the fieldbus
coupler/controller via blade-formed power jumper contacts. It then provides these
potentials to subsequent I/O modules via spring-formed power jumper contacts.

Do not exceed maximum current via power jumper contacts!
The maximum current to flow through the power jumper contacts is 10 A.
Greater currents can damage the contacts.
When configuring your system, ensure that this current is not exceeded.
If exceeded, insert an additional supply module.

With consideration of the power jumper contacts, the individual modules can be
arranged in any combination when configuring the fieldbus node. An arrangement
in groups within the group of potentials is not necessary.
