Реле контроля Omron K8AK-AW
Однофазное реле контроля тока, двухпороговое
Однофазные реле контроля тока следят за превышением и понижением тока. В одном реле поддерживаются автоматический и ручной сброс. Блокировка срабатывания при пуске и время срабатывания настраиваются раздельно. Состояние реле легко контролируется по светодиодному индикатору.
- Однофазное реле контроля тока, двухпороговое
- Корпус шириной 22,5 мм для промышленного применения
- Контроль понижения и превышения
- Номиналы напряжений питания: 24 В~/=, 100 - 240 В~
- Простое подключение цепей с использованием обжимных наконечников
