Description

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.
