1756-L1/ABPLC模塊

在控制電路中，輸入PLC的控制信號為32點，包括司機指令信號（如司機控制器、各琴鍵開關(guān)、按鈕開關(guān)等元件的觸點信號）和機車狀態(tài)信號（如溫度繼電器、壓力繼電器、柴油機轉(zhuǎn)速信號和機車速度信號等）。PLC輸出的控制信號點數(shù)為32點，包括動作執(zhí)行元件（各接觸器線圈、電空閥及去電子調(diào)速箱的控制信號）。

系統(tǒng)的核心部分，采用的是日本三菱公司的FX2—80MR—D型PLC。該機型為整體式PLC機，結(jié)構(gòu)緊湊、體積小、重量輕，具有很強的抗*力和負(fù)載能力。而且FX2系列PLC機是三菱公司90年代初推出的產(chǎn)品，它的大的特點是在小型機上實現(xiàn)大型機的功能，可與計算機自由聯(lián)接。（性能參數(shù)見表1）該機型有40個輸入點和40個輸出點。不帶擴展模塊，*系統(tǒng)的要求。機車速度和柴油機轉(zhuǎn)速傳感器采用了目前鐵路機車通用的數(shù)字式測速傳感器。
