Product Brief

0AC808.9 is B&R discontinued 8‑port layer 2 industrial Ethernet hub, widely used for POWERLINK real‑time bus and ordinary industrial Ethernet network topology expansion.

It adopts shielded RJ45 interface, supports auto‑negotiation and AUTO‑MDIX function, no need to distinguish straight‑through or crossover cable, simplifies field wiring work. Each channel is equipped with independent LED indicator, convenient for technicians to quickly judge link status, network collision and communication fault.

The module supports DIN‑rail installation, adapts to cabinet horizontal and vertical installation modes, with wide‑range DC power supply and perfect electrical isolation performance, can restrain ground loop interference in industrial site.

This is EOL discontinued spare part, mainly used for maintenance and renovation of old‑generation B&R automation control system. Please confirm network topology and matching terminal block before purchasing. Strict ESD protection should be followed during installation.
