5.6 DeviceNet eldbus coupler UR20-FBC-DN
The UR20-FBC-DN eldbus coupler is the head module for
the u-remote system bus, to which up to 64 active u-remote
modules can be connected. The DeviceNet coupler is con-
nected to the network with a 5-pole PCB plug-in connector.
The coupler can be accessed with a system-independent
web server application via the USB service interface. Thus,
all information, such as diagnostics, status values and para-
meters, can be read and all connected modules can be simu-
lated or forced.
The station’s main power supply is integrated in the coupler.
Power is supplied via two 4-pole connectors, separated into
the input and output current paths.
