The Plugtrab PT-IQ provides proactive functional monitoring for signal interface surge protection devices. A yellow status signal indicates that the performance limit has been reached as a result of frequent surge voltages, while a small reserve capacity ensures that protection remains effective. The user is informed and can replace the protective connector before the protective function fails due to component overload. Failure is indicated by a red signal. The remote signalling feature allows users to inspect the system from any location and at any time.
The controller assumes the management of a strip equipped with protective devices. It acts both as a power supply and an evaluation unit for all status signals. The system can be easily extended: a controller monitors and supplies up to 28 protective devices via the DIN rail connector. The system can also be expanded to another mounting rail.
The installation design, which includes an integrated rail-mounted bus, allows for quick and error-free assembly. The power supply and status signal are connected as soon as a module is snapped on, thus minimising the wiring effort.
