RUGGEDCOM RS401
Installation Guide
Introduction
The RUGGEDCOM 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.
Featuring an integrated 4 port serial server, a 4 port managed Ethernet switch, and an optional V.90 modem, the
RS401 is able to interconnect multiple types of intelligent electronic devices (IEDs) that have different methods of
communications. Using the RS401 results in fewer connectivity devices (which reduces overall system costs) and
also extends the useful life of existing legacy IEDs (which minimizes capital expenditure for new equipment).
The RS401's compact design makes it ideally suited for panel mount locations or installations with tight space
restrictions.
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, IEC1800-3
and NEMA TS-2. The RS401 also features a wide operating temperature range of -40 to 85 °C (-40 to 185 °F)
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 24 VDC, 48 VDC,
88-300 VDC and 85-264VAC, 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.
