(1)輸入/輸出擴(kuò)展模塊 S7-200 CPU上已經(jīng)集成了一定數(shù)量的數(shù)字量I/O點(diǎn),但如用戶(hù)需要多于CPU單元I/O點(diǎn)時(shí),必須對(duì)系統(tǒng)做必要的擴(kuò)展。CPU221無(wú)I/O擴(kuò)展能力,CPU 222*多可連接2個(gè)擴(kuò)展模塊(數(shù)字量或模擬量),而CPU224和CPU226*多可連接7個(gè)擴(kuò)展模塊。6DD1688-1AC1
S7-200 PLC系列目前總共提供共5大類(lèi)擴(kuò)展模塊:數(shù)字量輸入擴(kuò)展板EM221(8路擴(kuò)展輸入);數(shù)字量輸出擴(kuò)展板EM222(8路擴(kuò)展輸出);數(shù)字量輸入和輸出混合擴(kuò)展板EM223(8I/O,16I/O,32I/O);模擬量輸入擴(kuò)展板EM231,每個(gè)EM231可擴(kuò)展3路模擬量輸入通道,A/D轉(zhuǎn)換時(shí)間為25μs,12位;模擬量輸入和輸出混合擴(kuò)展模板EM235,每個(gè)EM235可同時(shí)擴(kuò)展3路模擬輸入和1路模擬量輸出通道,其中A/D轉(zhuǎn)換時(shí)間為25μs,D/A轉(zhuǎn)換時(shí)間]100μs,位數(shù)均為12位。基本單元通過(guò)其右側(cè)的擴(kuò)展接口用總線連接器(插件)與擴(kuò)展單元左側(cè)的擴(kuò)展接口相連接。擴(kuò)展單元正常工作需要+5VDC工作電源,此電源由基本單元通過(guò)總線連接器提供,擴(kuò)展單元的24VDC輸入點(diǎn)和輸出點(diǎn)電源,可由基本單元的24VDC電源供電,但要注意基本單元所提供的*大電流能力。SIEMENS BQ3100 3P 100A AMP 240V-AC MOLDED CASE CIRCUIT
