REX640 overview

Overview

REX640 is a powerful all-in-one protection and control relay for use in advanced
power distribution and generation applications with unmatched flexibility available
during the complete life cycle of the device – from ordering of the device, through
testing and commissioning to upgrading the functionality of the modular software and
hardware as application requirements change.
The modular design of both hardware and software elements facilitates the coverage
of any comprehensive protection application requirement that may arise during the
complete life cycle of the relay and substation.
REX640 makes modification and upgrading easy and pushes the limits of what can be
achieved with a single device.

Relay hardware

The relay includes a Ready LED on the power supply module that indicates the relay's
status. In normal situations, the Ready LED has a steady green light. Any other
situation that requires the operator's attention is indicated with a flashing light.
The relay has mandatory and optional slots. A mandatory slot always contains a
module but an optional slot may be empty, depending on the composition variant
ordered.
