BLITZDUCTORconnect - Easy. Safe. Robust.

The combined lightning current and surge arresters of the new BLITZDUCTORconnect series protect automation and measuring and control systems in industrial environments as well as information technology interfaces. A high lightning current discharge capacity and a low protection level make them ideal components for reliable terminal device protection. They are available in a compact or modular design and both variants have a width of only 6 mm. Functions such as the new secR release buttons and push-in technology help to minimise the installation effort.

The status indicator and a compatible remote signalling unit immediately report any failure in case of overload. Ex-approved versions of BLITZDUCTORconnect are available for intrinsically safe signal circuits.

The BLITZDUCTORconnect (BCO) arresters are available in different versions. They protect two single lines with a common reference potential (unbalanced interfaces) or one unearthed double line (balanced interface).

An arrester with a high cut-off frequency is available for balanced bus interfaces with high data rates, such as Profibus or RS485. For intrinsically safe signal circuits there is an Ex-approved version (dust and gas). Selecting the right arrester is simple via the interface.

All line connections are vibration-proof and designed with push-in terminal technology. The lines are therefore easy to connect without the need for tools. When servicing the modular arresters, only the module is replaced. The signal is still available via the base part. The protective function for the system can be quickly restored by simply plugging in a new module without rewiring. In order to remove plug-in modules without accidentally pulling an adjacent module, they are equipped with secR release buttons that enable precise and safe replacement.

The modular arresters have a disconnection function. Turning the module 180° and plugging it into the base part again interrupts the signal circuit for maintenance work. Measurements can thus be carried out quickly and without additional effort.

 

The arresters of the BLITZDUCTORconnect series are equipped with an integrated visual status indicator. This clearly indicates the status of the arrester (green/red). In the event of an arrester overload, the indicator turns red. It is also possible to monitor arrester groups with a stationary remote signalling unit. The status of an arrester group is reported to a higher-level control system via a potential-free break contact. The combination of transmitter and receiver unit in one device minimises the wiring effort during installation. At the same time, there is no need for additional parameterisation of the arrester modules. The overloaded components are disconnected from the signal circuit by defined arrester failure behaviour (fail-open). The signal circuit itself, however, remains active and is not interrupted. The system circuit remains available and ongoing operation is maintained until the arrester is replaced. This means that plants and systems can be operated safely and with high availability at all times.

 

Accessories such as PARTITION EXI for disconnecting intrinsically safe and non-intrinsically safe signal circuits round off the BLITZDUCTORconnect product portfolio.
