Product Description


The RuggedServer™ RS416 is an industrially hardened serial device server with an integrated, fully managed, Ethernet switch, designed to operate reliably in electrically harsh and climatically demanding environments. Featuring a modular design that can support IEEE 1588 and IRIG-B time synchronization, up to 16 serial ports and up to 4 Ethernet ports, the RS416 is able to interconnect and synchronize multiple types of intelligent electronic devices (IEDs). The time source is provided via IEEE 1588 v2 and converted to IRIG-B for distribution to the IEDs via the serial ports or dedicated IRIG-B cabling. Each serial port supports standard data communications plus an IRIG-B time-synchronization output. Using the RS416 results in fewer connectivity devices reducing overall system costs and extends the useful life of existing legacy IEDs minimizing capital expenditure for new equipment.


The RS416 provides a high level of immunity to electromagnetic interference and heavy electrical surges typical of environments found in electric utility substations, factory floors or in curb side traffic control cabinets. The RS416 meets or exceeds a wide range of industry standards including
IEC 61850-3, IEEE 1613, IEC 61000-6-2 and IEC 61800-3. The RS416 also features a wide operating temperature range of -40°C to +85°C allowing it to be installed in virtually any location. The embedded Rugged Operating System (ROS®) within the RS416 provides advanced layer 2 and layer 3 networking functions, advanced cyber security features, and a full array of intelligent functionality for high network availability and manageability. Coupled with the ruggedized hardware design, the RS416 is ideal for creating mission-critical, real-time, control applications in any harsh environment.

The RS416 is also backed by RuggedCom’s five year warranty and unsurpassed technical support.
