The HAW569 surge protection device from Endress+Hauser is suitable for protecting the electronics of field devices against destruction by overvoltage. Overvoltages occurring in signal lines (e.g. 4...20 mA), communication lines of the field buses (HART, PA, FF) and supply lines are safely dissipated to earth. The functionality of the transmitter or the electronics to be protected remains unaffected, as there is no disturbing voltage drop due to impedance-free coupling of the protective devices.
