DC voltage relay, for Modbus
UG 9431

The DC volage relay UG 9431 of the VARIMETER PRO series allows easy parameter setting, monitoring and diagnosis via a Modbus RTU interface. The measuring relay monitors DC networks for overvoltages and undervoltages as well as voltage range violations. Early detection of impending failtures and preventive maintenance prevent costly damage and as a user you benefit from the operational safety and high availability of your system.
