/O接口模块，也被称为I/O模块，是工业级远程采集与控制模块，提供了无源节点的开关量输入采集、继电器输出、高频计数器等功能。I/O模块分为I/O设备和I/O接口两个部分，代表单片机或者计算机数据的进出端口。

USIO21 I/O接口模块的功能主要包括：

进行端口地址译码设备选择。

向CPU提供I/O设备的状态信息和进行命令译码。

进行定时和相应时序控制。

对传送数据提供缓冲，以消除计算机与外设在“定时”或数据处理速度上的差异。

提供计算机与外设间有关信息格式的相容性变换。

提供有关电气的适配，还可以中断方式实现CPU与外设之间信息的交换。

USIO21 I/O模块可分为离散、模拟和特殊模块等多种类型，这些模块都可以安装在带有多个插槽的导轨或者机架上。每个模块插入其中一个插槽，实现与CPU和其他设备的连接。

/O interface module, also known as I/O module, is an industrial-grade remote acquisition and control module, providing passive node switching input acquisition, relay output, high frequency counter and other functions. I/O module is divided into I/O equipment and I/O interface two parts, representing the single chip computer or computer data in and out of the port.

The USIO21 I/O interface module provides the following functions:

Select a port address decoding device.

Provides the CPU with the status information of the I/O device and performs command decoding.

Timing and corresponding timing control.

Buffering of transmitted data to eliminate differences in "timing" or data processing speed between the computer and peripherals.

Provides a compatible transformation of the relevant information format between the computer and peripherals.

Provides the relevant electrical adaptation, and can also realize the exchange of information between CPU and peripherals in the interrupt mode.

USIO21 I/O modules are available in discrete, analog and special modules, all of which can be mounted on rails or racks with multiple slots. Each module plugs into one of the slots to connect to the CPU and other devices.
