HAW566 DIN rail surge protective device for installation in the control cabinet for power supply and communication signals with SIL and optional Ex approval
HAW566 DIN rail surge protective device for installation in the control cabinet
Field of application
The HAW566 surge protective device is used to protect electronic components from being destroyed. It ensures that overvoltage surges which occur in signal cables (e.g. 4 to 20 mA), in communication lines of Field buses (HART, PA, FF) and in power lines are safely limited or passed into the ground. The functionality of the electronic component to be protected is not affected as, using the impedance-free connection of the protection unit, interference voltage drops cannot be introduced.
Surge protective devices are used to weaken residual currents from upstream lightning protection steps and to limit system-induced or system-generated overvoltage surges
HAW566 units are primarily used in process automation and in measuring and communication technology within the water & wastewater, chemical, oil & gas as well as power & energy industry
Benefits
Increased plant availability as surge protective device is perfectly matched to the electronic components involved in process automation and process measuring technology
Protection of investment-intensive measuring devices
Optional available with intrinsically safe approvals for the application in Ex areas
Digital communications now provide a wealth of additional diagnostic and other information, enabling operational insights unachievable with simple 4-20mA measurements alone.
