K8AK-TH Temperature Monitoring

New product

Etkin ve kompakt sıcaklık alarm ünitesi

Bu sıcaklık izleme rölesi özellikle anormal sıcaklıkların izlenmesi ve sıcaklığın aşırı düşük ya da yüksek hale gelerek

cihazlara zarar vermemesi için dizayn edilmiştir. K8AK-TH sadece 22,5mm'lik incelik ile sıcaklık izleme fonksiyonu sağlar

DIP switch'ler ile basit fonksiyon ayarıSeçilebilen alarm kilitleme ve SV korumasıTermokupl veya Pt100 ve Pt1000 sensör girişi için çoklu giriş desteğiEnversör röle, Hata-emniyet seçilebilirLED'ler ile alarm durumları izlenir
