REM610 Motor Protection Relay
The motor protection relay REM610 is a versatile multifunction protection relay
mainly designed to protect motors in a wide range of motor applications.
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.
