Industrial Ethernet is recognised through different transmission media, with copper or fibre optic among others. Data transmission rates range from 10 Mbit/s, 100 Mbit/s to 10 Gigabit/s. Ethernet networks are primary installed with copper based twisted-pair lines and RJ45 plugs. This design provokes over voltages by capacitive and inductive influences in the net, caused by near-by or distant lightning strikes.
DME 100TX-4RJ is Weidmuller’s overvoltage protection module for Ethernet Cat. 5. This overvoltage protection for the Cat. 5 is designed as an adaptor and installed into the circuit near the device to be protected. The innovative module ensures a reliable limitation of the interference level.
The connection of the devices to be protected takes place with RJ45 sockets. Fast reacting suppressor diodes ensure high protection for signal lines. The PE connection of the devices is achieved via an M4 screw fixing, with a reduction of potential differences through a gas charge eliminator between ground and PE.
Additionally Weidmuller offers a variant DME 100TX-4 RJ TS 35 for rail-mounting. The module is screwed to the profile with a mounting base. The separate wiring of the earthing conductor is not needed and makes additional material dispensable. The solution ensures a high-value electrical contact of the PE connection against the mounting rail. Additionally it offers a real Plug and Play solution to Ethernet overvoltage protection.
