The precision and resolution of the input module are two different concepts that describe the measurement accuracy and resolution of the input module respectively.
Accuracy refers to the degree of difference between the measured results of the input module and the true value. Accuracy is usually expressed as a percentage or percentage of full scale. For example,AIP171 if the accuracy of the input module is 1%, it means that the difference between its measurement and the true value does not exceed 1% of the full scale.
Resolution refers to the minimum amount of change in the input signal that the input module can detect. Resolution is usually expressed in numerical quantities, such as bits or numbers. The higher the resolution, AIP171 the smaller the minimum amount of change in the input signal that the input module can detect, allowing for more accurate measurements.
When selecting input modules, it is necessary to select the appropriate precision and resolution according to the application requirements. If high precision measurement results are required, an input module with high precision needs to be selected. If you need to detect a very small amount of input signal change, you need to choose an input module with high resolution.
