Beckhoff KL3054 4 Kanallı Analog Giriş Terminali 4… 20 mA
KL3054 analog giriş terminalinin görevi, analog ölçüm sinyallerini elektriksel izolasyonla otomasyon cihazına iletmektir. Giriş elektroniği, güç kontaklarının besleme voltajından bağımsızdır. Toprak bağlantısı, girişler için referans potansiyeldir. Hata LED'leri bir aşırı yük durumunu ve kopuk bir kabloyu gösterir. KL3054, dört kanalı tek bir muhafazada birleştirir.
