在DCS系統(tǒng)中，卡件接線是一項非常重要的工作。正確的卡件接線可以確保系統(tǒng)的穩(wěn)定性和可靠性，并對系統(tǒng)的整體性能有著重要的影響。本文將介紹卡件接線的基本原理以及如何優(yōu)化卡件接線，從而提高DCS系統(tǒng)的可靠性和性能。
DCS參與電氣回路控制，則在電氣回路中運用到2位選擇開關(guān)，1位用于“就地控制”，2位用于“遠程控制”（DCS控制），其接線主要有兩種：
1、DCS電平信號控制
由DCS控制中間繼電器，DCS給出電平信號“1”，繼電器無源常開點閉合；DCS給出電平信號“0”繼電器無源常開點斷開，通過繼電器無源接點的閉合和斷開達到起停設(shè)備。
