MDP and FDB lightning barriers
Security for data and control systems in plants and industrial and potentially explosive areas
Data and control systems are omnipresent in modern buildings and plants. OBO solutions protect sensitive components reliably.
Measurement and control technology and fieldbus systems allow automated control of production lines or remote monitoring of many different types of sensors and actuators. Today, this technology forms the core of any modern industrial company. Their failure would result in high financial losses. To prevent this, the systems must be protected against surge voltages from inductive and capacitive couplings. OBO can offer reliable protection of the electronic system with a broad portfolio of surge protective devices and lightning arresters.
Areas of application
- Water supply
- Wastewater treatment plants
- Wind energy
- Production
- Industry
- Refineries, oil and gas industry
- Tunnels
- Office buildings
The plus of the MDP family for Ex areas
Surge protection in potentially explosive areas is an important topic. It is important here to protect costly measuring technology against the influence of surge voltages through atmospheric discharge. OBO lightning barriers are tested for intrinsic safety (ia) and are independently certified. With a high arresting capacity of 10 kA, they offer optimum protection for four-pole measurement and control applications. Different voltage variants offer a wide range of applications.
The plus of the Petrol Field Protector family
With the Petrol Field Protector data cable protection device, OBO Bettermann can offer a surge protective device for sensors in potentially explosive areas. The protector permits two or three-pole protection for all kinds of sensors. The protective device can be fastened directly on the sensor and wired in using the appropriate metric or NPT thread. The robust stainless steel housing means that even aggressive atmospheres are no problem. The intrinsic safety of the Petrol Field Protector has been independently tested and certified. It offers safety and availability wherever effective surge protection is required for safety-relevant applications.
Tested safety
The surge protective devices of the MDP and FDB series are tested for the fieldbuses Profibus (PA/DP) and Foundation Fieldbus. The blue MDPs have UL approval and, as with FDBs, are approved for use in areas at risk of explosion.
