DI模块是系统的16通道24VDC数字量输入模块，接入现场干接点信号，模块单元由一个 I/O 模块，一个模块底座，电源总线和通讯总线构成。面板提供了丰富的状态指示灯，用来显示模块电源情况和现场设备通讯，通道的工作状态，以增强工作的效率。

输入(1nput)模块和输出(Output)模块简称为I／O模块，它们是系统的眼、耳、手、脚，是外部现场设备和CPU模块的桥梁。   

输入模块用来接收和采集输入信号，开关量输入模块用来接收从按钮；选择开关、数字拨码开关、限位开关、接近开关、光电开关、压力继电器等过来的开关量输入信号；模拟量输入模块用来接收电位器、测速发电机和各种变送器提供的连续变化的模拟量电流、电压信号。

开关量输出模块用来控制接触器、电磁阀、电磁铁、指示灯、数字显示装置和报警装置等输出设备，模拟量输出模块月手来控制调节阀、变频器等执行装置。

The DI module is a 16-channel 24VDC digital input module of the system, which accesses the field dry contact signal. The module unit consists of an I/O module, a module base, a power bus, and a communication bus. The panel provides a wealth of status indicators to display the power supply of the module, the communication of the field equipment, and the working status of the channel to enhance the efficiency of the work.

The input (1nput) module and Output (Output) module, referred to as the I/O module, are the eyes, ears, hands and feet of the system and the bridge between the external field equipment and the CPU module.

The input module is used to receive and collect the input signal, and the switching input module is used to receive the slave button. Select switch, digital dip switch, limit switch, proximity switch, photoelectric switch, pressure relay and other incoming switch input signal; The analog input module is used to receive the continuously changing analog current and voltage signals provided by potentiometer, tachometer generator and various transmitters.

The switching output module is used to control the output equipment such as contactor, solenoid valve, electromagnet, indicator light, digital display device and alarm device, and the analog output module is used to control the actuator such as regulating valve and frequency converter.
