The Scalance XB unmanaged industrial Ethernet switch can be used in a line or star topology where simple plug-and-play connections and low-cost port expansion features are required. The switches are available with up to eight 10/100 Mbit/s ports. Offering an IP20 degree of protection in a small, compact design, the new line of switches are constructed with a durable plastic housing that is easily mounted on standard rails. Diagnostics available on the switch include power, link status and traffic data and are indicated by LEDs.
