Field of application

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 chemicals, pharmaceuticals, water and wastewater sectors as well as in the food industry.

Benefits

  • 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)
