Типовой RS-485 с гальваноразвязкой

Материал из eeWiki - открытая энциклопедия по электронике

Перейти к: навигация, поиск

Перед вами типовая схема RS-485, использующая в качестве опторазвязки сигнала ADUM,

позволяющий снять ограничение по скорости, присущее оптронам.

Ключ на 2N7002 обеспечивает переход в режим приема при сбое

управляющего МК.

Использование SN65LBC184 - ИС драйвера RS-485 со встроенными элементами

защиты позволяет предельно упростить схему подключения.

В качестве изолятора рекомендуем применение Si8431 или аналога.
