2 REX640 overview
2.1 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.

2.2 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.
