REX640 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.
