可編程控制器的輸入接線是指外部開關設備PLC的輸入端口的連接線。輸出接線是指將輸出信號通過輸出端子送到受控負載的外部接線。
I/O接線時應注意:I/O線與動力線、電源線應分開布線,並保持的距離,如需在一個線槽中布線時,須使用屏蔽電纜;I/O線的距離一般不超過300m;交流線與直流線,輸入線與輸出線應分別使用不同的電纜;數字量和模擬量I/O應分開走線,傳送模擬量I/O線應使用屏蔽線,且屏蔽層應一端接地。
PLC的基本單元與各擴展單元的連接比較簡單,接線時,先斷開電源,將扁平電纜的一端插入對應的插口即可。PLC的基本單元與各擴展單元之間電纜傳送的信號小,頻率高,易受幹擾。因此不能與其他連線敷設在同一線槽內。
