Surge arresters for field mounting
- Operating Voltage 24V/120V/230V
- Compact device for the protection of signal / communication lines
- Optionally available with SIL2 intrinsically safe approvals
- HAW569 units are primarily used within the chemicals, pharmaceuticals, water and wastewater sectors as well as in the food industry.
The HAW569 surge arrester 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 (HART, PA, FF) and in power lines are safely 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.
