The HAW569 surge protective device is used to protect electronic components in field devices 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 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.
HAW569 units are primarily used in process automation and in measuring and communication technology within the water and wastewater, chemical, oil & gas as well as power & energy industry.
优势
Compact device for the protection of signal / communication lines (Ex ia approval as an option) or for the simultaneous protection of signal, communication and supply lines (Ex d approval as an option)
Optionally available with SIL2 intrinsically safe approvals
Setting up and monitoring equipment at an ammonia plant presents significant challenges. Engie Energía uses advanced technological solutions, like remote communication devices in hazardous areas.
Surge arresters are applied to protect electronic components of a plant against overvoltage! Due to this, investment intensive measuring instruments are protected and the plant availability is increased.
