In measurement and control technology surge protection is a very important topic. Surge voltages are often coupled in due to the large number of signal cables installed in parallel. Depending on the structure of your system, you can use surge arresters with different designs and functions. Below you will find an overview of our plug-in surge arresters for measurement and control technology.
PLUGTRAB PT-IQ offers you a new, forward-looking surge protection system with a variety of new features. A particularly interesting feature is the multi-stage signaling of the protective devices. Each voltage-limiting component of the protective circuit is intelligently monitored.
A yellow status signal indicates that the performance limit has been reached as a result of frequent surge voltages. The arresters continue to function and your system is still protected. Replacement is, however, recommended in order to avoid unnecessary servicing.
Watch the video and discover how quickly and easily PLUGTRAB PT-IQ can be wired and integrated into a remote signaling concept.
If a predictive monitoring system such as PLUGTRAB PT-IQ is not required, you can also use PLUGTRAB PT modules in your system.
Protect up to five signal cables against surge voltage on a design width of 17.5 mm. Furthermore, PLUGTRAB PT modules are also suitable for use in the Ex area.
The COMTRAB modular product range from Phoenix Contact consists of protective plugs with protective circuits for various interfaces. One magazine accommodates up to 10 protective plugs.
The assembled magazine is inserted in a base element or in an LSA-PLUS disconnect strip.
Combination of plugs and magazine
The protective plugs have been developed as stand-alone individual modules. This means that they can also be used without a magazine, however an additional grounding rail is required. Nevertheless, combining plugs and a magazine is more convenient.
Simply snap the plugs into the magazine to create a single unit. The individual plugs can, of course, also be removed from the magazine.
The choice is yours:
In addition, a coarse protection plug protects interfaces with higher dielectric strength or is used as the first protection stage, for example, at transfer points in a lightning protection zone concept.
Plug-in arresters offer huge advantages:
When choosing surge protection for measurement and control technology, you need a convenient installation concept: use two-part devices, i.e., a base element or magazine and a protective plug.
