Реле контроля температуры Omron K8AK-TH
Данное реле контроля температуры создано специально для слежения за возникновением нештатных температурных режимов и для защиты оборудования от перегрева. Устройство K8AK-TH, обеспечивающее контроль температуры, заключено в миниатюрный корпус шириной всего 22,5 мм.
- Простая настройка функций посредством DIP-переключателя
- Выбор защелкивания сигнала аварии и защита установленного задания
- Несколько входов для подключения термопары или входа датчика Pt100 и Pt1000
- Реле с перекидным контактом: выбор отказобезопасного режима
- Светодиодный индикатор для сигнализации аварийных режимов
