Overview

Our integrated circuits and reference designs help you create new AC analog input module designs that provide reliable and repeatable fault detection and trip-time performance in protection relays. Whether you are looking for sensors to accurately measure voltage and current or need the right transformers, shunts, Rogowski coils and potential dividers, the following subsystems will help you design an input module to help protect your grid assets.

Design requirements

AC analog input module designs often require:

  • Isolated, multi-channel voltage and current measurement.
  • Accurate and fast conversion of voltage and current signals.
  • Low power and reliable connectivity with sensors.
