Реле контроля Omron K8DT-AS

Omron K8DT-AS

Однофазное реле контроля тока

Обнаружение неисправностей в электродвигателях и другом оборудовании по изменению тока. Работа в режиме обнаружения повышенного или пониженного тока.

  • Одно реле для контроля переменных и постоянных токов
  • Совместимость с серийно выпускаемыми трансформаторами тока (вторичный ток: 0…1 А или 0…5 А)
  • Настройка уровня срабатывания, гистерезиса, времени блокировки при пуске и времени срабатывания
  • Ширина 17,5 мм — экономия пространства в шкафу управления
  • Технология Push-in plus упрощает подключение проводов
  • Соответствие UL упрощает ввоз в Северную Америку
  • Отверстия на два провода в каждой клемме для удобного подключения других устройств
  • Добавлены модели с высоконадежными транзисторными выходами
  • Соответствие Директиве RoHS
