The voltage relay REU610 is a versatile multifunction protection relay mainly
designed for overvoltage and undervoltage protection and for supervision of
medium voltage distribution networks. The relay can also be used for protecting
generators, motors and transformers.
The relay is based on a microprocessor environment. A self-supervision system
continuously monitors the operation of the relay.
The HMI includes a liquid crystal display (LCD) which makes the local use of the
relay safe and easy.
Local control of the relay via serial communication can be carried out with a
computer connected to the front communication port. Remote control can be carried
out via the rear connector connected to the control and monitoring system through
the serial communication bus.
