IC693MDL645

IC693MDL645 S7-200CPU上的高速輸入、輸出端子，其接線與普通數(shù)字量I/O相同。但高速脈沖輸出使用直流晶體管輸出型的CPU（即DC/DC/DC型）。

NPN/PNP輸出的旋轉(zhuǎn)編碼器（和其他傳感器），能否接到S7-200CPU上？

都可以。S7-200CPU和擴展模塊上的數(shù)字量輸入可以連接源型或漏型的傳感器輸出，連接時只要相應(yīng)地改變公共端子的接法（是電源L＋連接到輸入公共端、還是電源的M連接到公共端）。

S7-200能否使用兩線制的數(shù)字量（開關(guān)量）傳感器？

可以，但保證傳感器的靜態(tài)工作電流（漏電流）小于1mA。西門子有相關(guān)的產(chǎn)品，如用于PLC的接近開關(guān)（BERO）等。

S7-200是否有輸入、輸出點可以復(fù)用的模塊？

S7-200的數(shù)字量、模擬量輸入/輸出點不能復(fù)用（即既能當作輸入，又能當作輸出）。
