1756-L1/ABPLC模块

 1756-L1/ABPLC模块

在控制电路中，输入PLC的控制信号为32点，包括司机指令信号（如司机控制器、各琴键开关、按钮开关等元件的触点信号）和机车状态信号（如温度继电器、压力继电器、柴油机转速信号和机车速度信号等）。PLC输出的控制信号点数为32点，包括动作执行元件（各接触器线圈、电空阀及去电子调速箱的控制信号）。

系统的核心部分，采用的是日本三菱公司的FX2—80MR—D型PLC。该机型为整体式PLC机，结构紧凑、体积小、重量轻，具有很强的抗*力和负载能力。而且FX2系列PLC机是三菱公司90年代初推出的产品，它的大的特点是在小型机上实现大型机的功能，可与计算机自由联接。（性能参数见表1）该机型有40个输入点和40个输出点。不带扩展模块，*系统的要求。机车速度和柴油机转速传感器采用了目前铁路机车通用的数字式测速传感器。
