DDW-142 - Ethernet Extender
The DDW-142 Ethernet Extender is designed for use in tough environments and mission critical railway, road or utility applications where device failure could result in significant cost. The rugged and very compact unit can operate in extreme temperatures (-40 to + 158 F) and where EMC and vibration levels are high. Total galvanic isolation and transient protection of electronics contribute to a MTBF of 437,000 hours, ensuring high operational reliability and a long service life. The DDW-142 is transparent for multicast addressing, allows VPN pass-through for IPSec and can be used with protocols like Modbus/TCP and PROFINET I/O. The DDW-142 also features a Link Fault Forward (LFF) functionality whereby the Ethernet link status is sent over the SHDSL link between two units
