Here's something to bear in mind. Signal interfaces are particularly sensitive to surge voltages. You should therefore use our surge protection with components that are powerful and respond quickly. The right selection ensures low attenuation and, at the same time, high bandwidth.

Your advantages

  • Conformance with all standards – both for surge protection and for high-speed networks
  • Protection for all common applications and signals, thanks to the complete product portfolio
  • Versatile use, thanks to application-specific designs and connection technologies
  • Easy testing, thanks to plug-in arrester

DATATRAB DT – universal protection for information technology

DATATRAB DT from Phoenix Contact: protection for numerous IT applications  

DATATRAB product range

The DATATRAB DT product range from Phoenix Contact offers protection for numerous applications:

  • High-speed networks, up to 10 gigabit Ethernet
  • Networks with RS-485 interface
  • Analog and digital interfaces for telecommunications, including DSL

All surge protective devices are system-compliant and have the appropriate connection technology.

DT-LAN-CAT6+ supports various data protocols at very high transmission speeds: such as Ethernet, Power over Ethernet (PoE), ISDN, token ring, and DS1.

DATATRAB can either be used as an adapter or as a DIN rail module.

Typical areas of application

Surge protection for IT from Phoenix Contact  


Protective devices for information technology are split into two areas:

  • Data interfaces
  • Telecommunications applications

Data technology works with very low voltages and high transmission speeds. In contrast, due to the cable infrastructure, telecommunications systems use lower data transmission speeds in conjunction with higher voltages.

PLUGTRAB PT-IQ for data interfaces

PLUGTRAB PT-IQ also for data interfaces  

PLUGTRAB PT-IQ intelligent surge protection

PLUGTRAB PT-IQ intelligent surge protection now also reliably protects your data cables against surge voltages. The protective circuit is specifically tailored to HF applications. All voltage-limiting components in the protective circuit are permanently monitored.

Your advantage: pre-existing damage caused by frequent surge voltages is detected and indicated. Thanks to the multi-stage status display, you can determine the status of the arresters at any time:

  • Red = replacement required
  • Yellow = replacement recommended
  • Green = arrester function OK

Using the controller, group remote signaling can be implemented for all connected protective devices. You can choose between conventional screw connection and convenient push-in connection technology.
