This product group consists of modems that can be connected to the public telephone network. The modems are approved in most European countries and in many countries in other parts of the world.

Westermo modems are designed for industrial applications, which means that there are functions built in to them that are especially useful in industrial systems like for instance PLC connection mode and DIP switch settings. The Westermo products have a watchdog function and are galvanically isolated to give reliable communication in harsh environments. Some of the modems can also be used on 2- or 4-wire leased lines over very long distances. We also have modems that can be used for long distance multidrop applications.
