RuggedVDSL™ RS920L



The RuggedVDSL RS920L is an industrially hardened serial device server and managed Ethernet switch supporting Ethernet over VDSL (EoVDSL). The RS920L can be configured with up to 2 EoVDSL interfaces and 2 serial ports (RS485/ RS422/RS232). The EoVDSL interface allows for aggregation of serial devices at a remote location back to the central control room using existing telephone grade cable (or other legacy serial cabling). The EoVDSL uplink allows up to 4km LAN segments at up to 35Mbps. The dual EoVDSL interfaces is ideal for ring or loop network architectures and is the perfect solution for bringing Ethernet networking to serial devices at remote locations and applications where existing wiring is already present, thus saving the considerable cost of upgrading existing legacy devices or installing new network cabling.

Designed to operate reliably in harsh industrial environments the RS920L 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. An operating temperature range of -40°C to +85°C coupled with hazardous location certification, optional conformal coating and a galvanized steel enclosure allows the RS920L to be placed in almost any location.

The RS920L is packaged in a compact, galvanized steel enclosure that allows either DIN or panel mounting for efficient use of cabinet space. The RS920L provides an integrated power supply with a wide range of voltages (88-300VDC or 85- 264VAC) for worldwide operability or dual-input, reversible polarity, 12VDC, 24VDC and 48VDC power supply inputs for high availability applications requiring backup power inputs.

The RS920L's superior ruggedized design coupled with the embedded Rugged Operating System (ROS™) provides improved system reliability and advanced networking features making it ideally suited for creating Ethernet networks for mission-critical, real-time, control applications.

All RuggedCom products are backed by a five year warranty and unsurpassed technical support.
