Multifunction relay

Block diagram


Our integrated circuits and reference designs help you design multifunction relays with protection, monitoring and diagnostic features integrating data acquisition, signal processing, protection algorithms, high- or low-speed communication, isolation and human machine interface (HMI) functionalities.

Design requirements

Innovative and highly-integrated multifunction relay designs often require:

  • Accurate measurement of alternating current (AC) and voltage inputs over a wide range.
  • Communication interfaces, including Ethernet copper/fiber 10/100/1000, USB and RS-485.
  • Efficient direct current (DC) supply using DC/DC converters with an integrated inductor and onboard power management.
  • HMI solutions for LCDs for graphic display and LEDs for diagnostics and status indication.
