B&R X20PS9402

Supply for the bus controller, X2X Link and internal I/O supply Low-cost supply module for small X20 system Feed and bus controller / X2X Link supply not electrically isolated Expansion or redundancy of bus controller / X2X Link supply not possible by operating multiple supply modules simultaneously The supply module is used together with an X20 bus controller. It is equipped with a feed for the bus controller, the X2X Link and the internal I/O supply. The module is designed to supply power for smaller X20 systems. Potential groups are able to be formed. An expansion or redundancy of the X2X Link with the X20PS3300 or X20PS3310 supply module is not possible. Expansion of the X20 system with a bus transmitter is not permitted either.
