输入继电器作为PLC接收外部主令信号的器件,通过接线与外部输入设备相联系,其"线圈"状态只能由外部输入信号驱动。 输入设备选用的是按钮SB0的常闭触点,输入继电器X0的线圈状态取决于SB0的状态。该按钮未按下时,输入继电器X0线圈状态为"1"通电状态,程序中所有X0触点均动作,即常开触点接通,常闭触点断开;若按下该按钮,则输入继电器X0线圈状态为"0"断电状态,程序中所有X0触点均恢复常态。如果输入继电器连接的输入设备是按钮SB0的常开触点,则情况恰好相反:在该按钮未按下时,输入继电器X0线圈状态为"0"断电状态,程序中所有X0触点均不动作;若按下该按钮,输入继电器X0线圈状态为"1"通电状态,程序中所有X0触点均动作。
