RuggedServer RS401



The RuggedServer™ RS401 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. Based on the popular RuggedServer™ RS400, the RS401 includes all the same functionality including an integrated 4 port serial server, 4 port managed Ethernet switch, and optional V.90 modem. In addition, the RS401 features a more compact design that is particularly suited for panel mount locations or installations with tight space restrictions. The RS401 is an ideal device to connect and “IP-enable” legacy serial devices or IEDs for Ethernet network connectivity.

The RS401 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 RS401 meets or exceeds a wide range of industry standards including IEC61850, IEEE1613, IEC61000-6-2, IEC61800-3, and NEMA TS-2. The RS401 also features a wide operating temperature range of -40°C to +85°C allowing it to be installed in virtually any location.

The RS401 also includes an industrially rated integrated power supply that can support a wide range of power supply options suitable for multiple industries and for worldwide operability. Options include 24VDC, 48VDC, and 88VDC - 300VDC/85VAC - 264VAC, allowing for great installation flexibility.

The embedded Rugged Operating System (ROS™) within the RS401 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 RS401 is ideal for creating mission-critical, real-time, control applications in any harsh environment.

The RS401 is backed by RuggedCom’s all inclusive five year warranty and unsurpassed technical support.
