Beckhoff KL3311 1 Kanallı Termokupl Giriş Terminali
açık devre tanıma ile
KL3311 analog giriş terminali, termokuplların doğrudan bağlanmasına izin verir. Veri Yolu Terminalinin devresi, 2 telli tekniği kullanarak termokupl sensörlerini çalıştırabilir. Tam sıcaklık aralığında doğrusallaştırma, bir mikroişlemci yardımıyla gerçekleştirilir. Sıcaklık aralığı serbestçe seçilebilir. Hata LED'leri, kopuk bir kabloyu gösterir. Soğuk bağlantı için telafi, terminallerde bir iç sıcaklık ölçümü ile yapılır. KL3311, mV ölçümü için de kullanılabilir.
