Fieldbus coupler 750-342
Hardware
3.1.2.2 Device supply
The supply is made via terminal bocks with CAGE CLAMP® connection. The
device supply is intended both for the system and the field units.

G034201e
The integrated internal system supply module generates the necessary voltage
to supply the electronics and the connected I/O modules.
The fieldbus interface is supplied with electrically isolated voltage from the
internal system supply module.
3.1.2.3 Fieldbus connection
Connection to the fieldbus is by an RJ45 connector. A category 5,
shielded/unshielded twisted pair cable (S-UTP) with an impedance of 100
Ohm ±15% is mandatory as a connecting line for the 10BaseT Interface.
The connection point is physically lowered for the coupler/controller to fit in
an 80 mm high switch box once connected.
The electrical isolation between the fieldbus system and the electronics is
achieved by means of DC/DC converters and optocouplers in the fieldbus
interface.
