PDP Pluggable Data Cable Protection

Product catalog summary

Introduction
The document introduces the PDP(-OS) device series, designed to protect measurement and control technology systems from data cable interference and surge voltages, crucial in modern industrial settings.

Data Cable Protection and EMC
Data cables are vulnerable to interference, necessitating effective shielding and earthing to prevent inductive, magnetic, and capacitive coupling. The PDP series offers solutions for both directly and indirectly earthed systems to ensure system availability and prevent downtime.

Direct and Indirect Shield Earthing
Direct earthing is recommended for cables within buildings with consistent earthing potentials, providing robust protection. Indirect earthing is suitable for long cables or those between buildings, using a gas discharge tube (GDT) to manage potential differences and prevent shield load.

PDP and PDP-OS Devices
The PDP series includes plug-in arresters tested to DIN EN 61643-21 standards, supporting frequencies up to 100 MHz. They offer high discharge current capacity and impulse durability, with options for direct and indirect earthing. The PDP-OS variant includes visual and remote signalling capabilities.

Technical Specifications
The document provides detailed specifications for various PDP models, including maximum continuous voltage, voltage protection levels, and impulse durability. The devices are designed for easy maintenance and high system availability.

Product Data and Power Supply
The PDP-PS power supply supports up to 25 surge protective devices, with options for remote signalling and visual indicators for device status.

Conclusion
The PDP series offers comprehensive protection for data cables in industrial environments, ensuring reliable operation and minimizing downtime risks.

Data cable protection and EMC Measurement and control technology forms the core of modern industrial companies. In this era of Industry 4.0, they enable the automated control and remote monitoring of systems, sensors and actuators. To ensure system availability and prevent financial losses due to production downtimes, OBO surge protective devices protect electronics against damage caused by lightning strikes and surge voltages. Due to their sensitive signal levels, data cables are particularly susceptible to interference, meaning that cable shields are used to minimise this. However, if the shield...

Direct shield earthing The direct earthing of the shield on both sides should always be chosen when dealing with cables which are routed within a building and the earthing potentials do not differ from each other at the ends of the cable. This guarantees good protection against inductive, magnetic and capacitive couplings. Indirect shield earthing When dealing with particularly long cables or cables between buildings, it is wise to earth the shield indirectly on one side. For this, the shield is connected with the earth potential directly at one end of the cable and using a GDT* at the other...
