输入阻抗和输出阻抗是电子设备和系统中的重要参数，它们分别表示输入端和输出端的等效阻抗。

输入阻抗是指一个电路输入端的等效阻抗，通常用输入电阻来表示。在输入端上加上一个电压源，测量输入端的电流，则输入阻抗就是电压源与电流的比值。输入阻抗反映了对电流阻碍作用的大小，对于电压驱动的电路，输入阻抗越大，则对电压源的负载就越轻，因而就越容易驱动，也不会对信号源有影响。而对于电流型驱动的电路，输入阻抗越小，则对电源的负载就越轻。

输出阻抗是指一个信号源的内阻。对于一个理想的电压源，内阻应该为0；而理想电流源的阻抗应当为无穷大。输出阻抗反映了设备和系统对输出信号的阻碍作用，它会影响输出信号的大小和稳定性。在设计和使用电子设备和系统时，需要考虑到输入阻抗和输出阻抗的影响，以确保信号的正确传输和处理。

【英文介绍】

The BMXAMI0800 is a Schneider non-isolated analog input module with high-function fast input and 8-channel features. This module is suitable for multi-range (voltage/current) applications and offers high speed, high precision performance. In addition, the BMXAMI0800 has a non-isolated interchannel feature with a High level input and an analog input type of current +/ -20 mA.

Input impedance and output impedance are important parameters in electronic devices and systems, they represent the equivalent impedance of the input and output respectively.

Input impedance refers to the equivalent impedance of the input end of a circuit, usually expressed by the input resistance. Add a voltage source to the input, measure the current at the input, and the input impedance is the ratio of the voltage source to the current. The input impedance reflects the size of the current blocking effect, for a voltage driven circuit, the greater the input impedance, the lighter the load on the voltage source, and therefore the easier it is to drive, and will not affect the signal source. For current-mode driven circuits, the smaller the input impedance, the lighter the load on the power supply.

The output impedance is the internal resistance of a signal source. For an ideal voltage source, the internal resistance should be 0; The impedance of an ideal current source should be infinite. The output impedance reflects the hindrance of the equipment and system to the output signal, which will affect the size and stability of the output signal. When designing and using electronic devices and systems, it is necessary to take into account the influence of input impedance and output impedance to ensure the correct transmission and processing of signals.
