Motor protection relay & contactors

Products and reference designs

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.

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.
