数字扩展单元是可编程控制器扩充系统规模的一种单元，其特点和使用场景可以归纳如下：

定义与功能：

DSDX453   数字扩展单元是用于增加可编程控制器（如PLC）系统的输入输出点数的一种设备。

它不能单独使用，需要通过扩展口与主机相连，从而扩展系统的功能。

应用场景：

DSDX453  当控制对象需要的控制点数超过了PLC主机自带的I/O点数时，就需要使用数字扩展单元来增加输入输出点数。

在工业自动化生产、安防监控系统、自动化测量与控制系统中，数字扩展单元的应用尤为广泛。

特定需求与解决方案：

在某些特殊情况下，如外围设备反馈电压高于PLC的反馈电压时，可能需要使用继电器来保护PLC的I/O端口。

对于I/O信号的中继隔离需求，也可以通过数字扩展单元来实现，以避免损坏PLC的I/O端口。

Digital expansion unit is a programmable controller to expand the system scale of a unit, its characteristics and use scenarios can be summarized as follows:

Definition and functions:

The DSDX453 Digital expansion unit is a device used to increase the number of input and output points of a programmable controller (such as PLC) system.

It cannot be used alone. It needs to be connected to the host through an expansion port to expand the functions of the system.

Application scenario:

DSDX453 When the control object needs more control points than the PLC host I/O points, it is necessary to use a digital expansion unit to increase the input and output points.

In industrial automation production, security monitoring systems, automated measurement and control systems, digital expansion units are particularly widely used.

Specific needs and solutions:

In some special cases, such as when the peripheral feedback voltage is higher than the PLC feedback voltage, it may be necessary to use a relay to protect the PLC I/O port.

The relay isolation requirements for I/O signals can also be achieved through digital expansion units to avoid damaging the PLC's I/O ports.
