XN standard gateways
The standard line of XI/ON contains gateways with and gateways without an integrated power
supply unit:
The integrated power supply unit U
SYS
feeds the gateway and in a limited range (note the
permitted current I
MB
) the communication part of the connected I/O modules. Additionally, the
field voltage distributed via the system interne current rail system is fed by the further voltage
U
L
. Because of this, a XN-GWBR gateway does not require the XN-BR-24VDC-D module
which is necessary with XN-GW gateways.

Note
The gateway types XN-GW-… need an additional power supply module (bus refresh-
ing module) which feeds the gateway an the connected I/O modules.
