5.7 CANopen eldbus coupler UR20-FBC-CAN
The UR20-FBC-CAN eldbus coupler is designed according
to the international standard (EN50325-4). It is the head
module for the u-remote system bus, to which up to 64 ac-
tive u-remote modules can be connected. The CANopen cou-
pler has a Sub-D socket and supports the CiADS401 device
prole.
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 param-
eters, 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.
