The SDW-550 E-mark is an unmanaged 5-port industrial Ethernet switch designed for easy use in road vehicles. The unit supports 802.1Q long packets which allows all standard industrial Ethernet protocols to be used.

The SDW-550 E-mark is designed for use in industrial applications and so has dual power inputs for 10 to 57 VDC operation. Total galvanic isolation between each port is reinforced by the unique isolation provided between each chassis screen helping to avoid ground loop currents. The IP 21 rating ensures that the unit can be installed in locations where condensed water may occur.

Only industrial-grade components are used which gives the SDW-550 an MTBF of 675,000 hours and ensures a long service life. A wide operating temperature range of –25 to +70°C (–13 to +158°F) can be achieved with no moving parts. Both Westermo and external test houses have tested the SDW-550 to meet numerous EMC, isolation, vibration, and shock standards, all to the highest levels suitable for heavy industrial environments.

Network diagnostics are simplified with the inclusion of port mirroring on one port allowing data flow through the switch to be monitored using a network analyzer. All five ports can have data rate and flow control locked by the DIP switch which can eliminate problems with old legacy Ethernet equipment that is unable to support auto negotiation.


End of Life Product - No Replacement

Please note that the SDW-550 has been phased out. You can explore the SDI-862-MM-SC2SDW-550-T5G, and SDW-541-F1G-T4G in the Unmanaged Ethernet Switches.
