Digital output ter-
minals need a field
supply of 5 VDC or
24 VDC depending
on the module type.
Fig. 29 Separated
power units for sys-
tem and field supply
(Ethernet)
After mounting of the modules, the required wiring has to be installed.
Connect the “System supply (out)“ contacts of the OU-Filter module to the “System supply (in)“ contacts
of the OU-Fieldbus Coupler (0 V and 24 V, see
).
Connect the system supply (in) of the OU-Filter module to the power supply (0 V and 24 V, see
).
Connect the field supply (in) of the OU-Filter module to the power supply (0 V and 5 V/24 V, see
i
The system supply and field supply should be separated to ensure the bus operation and electrical
isolation in case of a short-circuit of an actuator.
