Overvoltage protection
To protect against overvoltage in the power supply and signal/communication cables for the
thermometer electronics, Endress+Hauser offers the HAW562 surge arrester for DIN rail mounting
and the HAW569 for field housing installation.
For more information see the Technical Information 'HAW562 Surge arrester' TI01012K and
'HAW569 Surge arrester' TI01013K.
