Protection and control REX640

REX640 is a powerful all-in-one protection and control relay for advanced power generation and distribution applications. REX640 offers unmatched flexibility throughout its entire life cycle – from ordering through testing and commissioning, to upgrading the functionality of its modular software and hardware to meet new application requirements. As a member of ABB’s Relion® protection and control family of relays, REX640 further reinforces Relion’s position as the range of relays to rely on.

Scope

• All-in-one protection and control
  

Benefits

• Complete application coverage with one device for optimal flexibility and cost-effectiveness
• Ready-made application packages for convenient and smooth ordering
• Fully modular hardware and software for maximum flexibility throughout the entire relay life cycle
• Easy adaption to changing protection requirements
  
• Optimal situational awareness and usability with application-driven LHMI/SHMI (switchgear HMI)
• Ready-made application-based LHMI pages – saving both time and efforts
  
• Relay costs reduced by up to 15% with SHMI instead of LHMI

Features
