Многоканальный монитор с интеллектуальным управлением KM1

Omron KM1

Многоканальный монитор с интеллектуальным управлением

Платформа KM1 позволяет визуализировать потребление электроэнергии при использовании на задней панели с помощью концепции "ведущий-ведомый". К ведущему блоку можно подключить до четырех ведомых для осуществления одновременного измерения электрических и неэлектрических параметров.

  • Существенно сокращено время установки.
  • Пространство для установки уменьшено на 24% по сравнению с традиционными средствами для контроля.
  • Уменьшено количество устройств: с помощью одной платформы можно измерить до 36 контуров.
  • Количество проводных соединений также уменьшено благодаря высокоскоростному соединению внутренней шины Innerbus и напряжению источника питания ведущего блока.
  • Настраиваемая платформа для любой области применения
  • Удобная классификация объединенной энергосистемы благодаря настраиваемым внутренним пороговым значениям
  • Высокоточные измерения даже для токов ниже 5% от номинального значения.
  • Отсутствие необходимости использовать трансформатор напряжения / До 7 импульсных выходов для сбора данных, в том числе, о неэлектрических параметрах
  • Оснащен входом температуры
  • Бесплатная программа для конфигурации KM//KE1
  • Двойной мониторинг системы с помощью одного блока
