Release of new functionality for the all-in-one protection and control relay REX640

2023-09-19 Release announcement

We are pleased to announce the release of two new modules for REX640, ABB’s all-in-one protection relay for advanced power generation and distribution applications. The new RTD module allows the hardware configurations to be optimized and binary and analog inputs to be mixed to meet process-specific requirements. The new sensor input module supports using current and voltage sensors according to the latest IEC 61869 standard. This increases the interoperability of substation automation devices, which facilitates the transition towards digital switchgear.


What's new?

  • RTD module RTD2 (RTD1002) with 3 RTD inputs, 6 mA channels (inputs/outputs) and 12 binary inputs for configuration optimization
  • Sensor input module SIM2 (SIM1902) to allow sensor connections according to the latest IEC 61869 standard

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). 

Supported languages

REX640 LHMI is available in English, Chinese, German, Swedish, Spanish, Russian, Polish, Portuguese, Italian, French, Czech, Croatian and Slovenian. Additional language support will be announced later. For some languages other than English, the translation of certain text strings might not be available at the time of the release of new functionality. The language packages will be updated soonest.
