We are pleased to announce the release of a narrow hardware variant of REX640 with five instead of seven module slots. This makes our all-in-one protection and control relay for advanced power generation and distribution applications suitable for smaller switchgear too. Detachable connectors further facilitate wiring installation in tight spaces.
Similar dimensions make the narrow variant of REX640 a convenient alternative for replacing, for instance, ABB’s REF 542, REF 542plus, RE_ 541/3/5 and 630 series relays, to ensure the power protection system meets today’s and future requirements as the grid evolves.
What's new?
- Narrow hardware variant with 5 module slots
Product range
Protection and control REX640, product connectivity level 4 (PCL4)
Customer benefits
- Complete application coverage with one freely configurable device for flexible and cost-effective tailoring to application-specific requirements
- Ready-made application packages for convenient and smooth ordering
- Fully modular hardware and software for maximum flexibility and easy adaption to changing protection requirements throughout the entire relay life cycle
- Optimal situational awareness and usability with application-driven LHMI/SHMI (switchgear HMI)
- Ready-made application-based LHMI pages – such as support for a 64-channel alarm annunciator (SACO) – saving both time and efforts
- Savings of up to 15% on relay costs with SHMI instead of LHMI – while still maintaining full LHMI functionality on panel/bay level for optimal visibility
Target markets
REX640 is targeted at the global market for medium-voltage protection and control applications (IEC, CN and ANSI).
