Формирователи сигналов JUXTA серии W

Компактный размер, универсальный монтаж и обеспечиваемая микропроцессором высокая эффективность делают устройства серии W отличным решением для многих областей применения. Характеристики формирователей сигналов серии W такие же, как у формирователей сигналов серии F, за исключением напряжения питания, второго выхода и ширины корпуса.

Подробно

  • Компактная конструкция обеспечивает экономию места: 72 (В) x 48 (Ш) x 127 (Г) мм
  • Конфигурирование на месте эксплуатации (WA5, WH2, WH5, WM1, WR5, WT5, WS1)
    Функция конфигурирования на месте эксплуатации микропроцессорных устройств серии F позволяет настраивать, изменять и контролировать диапазон, ноль/шкалу, выгорание и прочее с ПК пользователя (используя инструмент настройки параметров VJ77 для ПК)
  • Минимизация числа резервных блоков
    Например, на формирователях сигналов модели WT5 с входом для термопары можно настроить тип входа, диапазон входа и прочее с помощью ПК (с VJ77). Одно устройство WT5 может поддерживать 8 типов термопар
  • Контакты для подключения находятся на фронтальной панели, поэтому формирователь сигналов можно проверить даже под напряжением
  • Универсальные характеристики входа/выхода отвечают широкому диапазону областей применения
  • Доступны модели с одним и двумя выходами
    Второй выход (от 1 до 5 В пост. тока) предоставляется по отдельному заказу (кроме WA0A, WC0A, WH0V)
