PLC由哪幾部分硬件組成？
PLC的硬件一般由主機(jī)、I/O擴(kuò)展機(jī)及外部設(shè)備組成。
（1）主機(jī)包括：微處理器（MPU）。常用的微處理器有：Z80A、8085、M6800、M6809、8086、M68000。單片機(jī)有：8039、8031、M6801。
存儲(chǔ)器：PLC的存儲(chǔ)器用于存儲(chǔ)程序和數(shù)據(jù)，一般采用ROM或EPROM。
I/O接口：I/O接口是主機(jī)與外部設(shè)備、I/O模塊等的連接部件，用于擴(kuò)棄PLC總線的驅(qū)動(dòng)能力輸入輸出點(diǎn)數(shù)。
（2）電源：電壓范圍在160VAC-260VAC。
（3）輸入/輸出模塊：用于調(diào)理輸入輸出信號(hào)，對(duì)輸入信號(hào)進(jìn)行濾波、隔離、電平轉(zhuǎn)換等。包括直流開關(guān)量輸入模塊，交流開關(guān)量輸入模塊，直流開關(guān)量輸出模塊，交流開關(guān)量輸出模塊。
（4）功能模塊：包括A/D模塊和D/A模塊，溫度傳感器模塊，高速計(jì)數(shù)模塊，PID模塊，遠(yuǎn)程I/O模塊，通訊模塊。
（5）擴(kuò)展口
（6）編程器
（7）其他外設(shè)：打印機(jī)，顯示器。
