B&R X20BT9100
X2X Link bus transmitter For seamless expansion of the system Up to 100 m segment length Supply for internal I/O power supply Operation only on the rightmost slot The bus transmitter is used for seamless expansion of the X20 system. Stations can be up to 100 m apart. The bus transmitter module is only permitted to be operated with a bus module where the internal I/O power supply is connected through (e.g. X20BM11). If the supply is used for the internal I/O power supply, this potential group is not permitted to be supplied by any other module. An I/O module with bus module X20BM01 must be used to isolate the potential group.
