The diffusion of local area networks and particularly of Ethernet networks in an industrial environment is steadily growing;there are always more request for high speed communication with high reliability products. Sm@rtSwitch in its various configurations is the product that surely satisfies the constraints of an heavy environment; the simplicity of use, thanks to the automatic identification of the transmission speed and negotiations of line parameters, to the identification of the polarity and of the type of used wiring, allows an easy use, reducing the installation cost.

A particular feature has been engineered to allow the notification of functional anomalies through relais contacts that can be connected to a supervisory PLC.

The equipment can also be used as protocol converter between copper twisted pair cable and multimodal or monomodal optical fiber, to extend the maximal distance of the connections up to 2 or 15 km.

The production and engineering of Sm@rtSwitch are entirely made in Italy, a guarantee of quality and reliability and of constant availability of the product over the years.

8 ports with automatic switching between 10 and 100 Mb/s : it executes the packet switching at the highest speed possible

Assembly with screws or DIN guide with rapid coupling: ideal for the use in industrial environment

Complete scalability: the 100Base-FX connection with multimodal optical fiber (full duplex ) allows a secure connection, immune to electromagnetic disturbances, up to 2 km away (optionally 15 km with monomodal fiber)

Auto-MDIX: it identifies automatically and it conforms to the used wiring, direct or cross, for an extreme facility of use

The redundant supply allows 2 different power sources

The state of connection on the 10/100Base-Tx ports is marked by the closing of a potential free contact; so it becomes easy to control the connections’ state

It measures the input rate of multicast and broadcast packets; in the case there are more than 54 such packets consecutively from a same ports, they are rejected for the successive 800 milliseconds, in order to avoid the block of the network.
