Built‑in function:Real‑time Ethernet gateway converts POWERLINK field‑bus traffic into Series2003 local backplane I/O signals. Integrated hub simplifies field wiring without extra external switch. Galvanic‑isolated ports restrain ground‑loop interference for motion‑critical automation. Rotary dial realizes fast station‑number setting on site. LED indicators quickly locate bus communication fault. It allows Series2003 screw‑in I/O modules to work as remote POWERLINK controlled nodes.

Product Brief

7EX484.50‑1 is high‑end POWERLINK bus gateway of B&R Series2003 control system. Different from single‑port 7EX481.50‑1,it integrates four RJ45 ports with internal hub,supports flexible network topology for multi‑axis motion‑control projects.

Each POWERLINK port adopts galvanic isolation design,improves system stability under heavy‑interference industrial workshop. Rotary dial switch can set station number without software configuration,convenient for field commissioning and replacement. Multi‑color LED monitors module running status,bus error and port sending‑receiving activity for fast troubleshooting.

This is legacy EOL discontinued spare part,widely used for maintenance and hardware replacement of old‑generation motion‑oriented Series2003 distributed automation lines. Before purchase,please confirm Series2003 base holder compatibility and POWERLINK master station matching. ESD anti‑static protection shall be performed during installation,hot‑swap under powered‑on state is prohibited. Power terminal block must be purchased separately.
