MultiCOM 421 is a network card that easily enables you to connect a Riello UPS unit to a Profinet IO network.

Profinet is a further development of the Profibus field bus communications standard. It is designed to collect data from and control equipment in industrial systems, with a particular strength in delivering data under tight time constraints.

Employing universal Ethernet-based communication, Profinet is ideal for automation applications and industrial environments including the oil and gas sector.
