Use field side connection modules!
Where required, use the appropriate field side connection modules for power
supply to the sensors.

The I/O module inputs provide high-side switching. If the 24 V potential for field
power is switched to an input connection, the signal status for the corresponding
input channel is set to “high”.

The I/O module 750-1405/040-000 (16DI 24VDC 3ms XTR) 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.
