1. What is analog input module

1.1 Analog signal and digital signal

In industrial control and monitoring, analog signals refer to continuously changing physical signals, such as temperature, pressure, flow, etc. Digital signals are discrete signals that can only be represented by fixed values. The function of analog input module is to convert analog signal to digital signal so that the computer or control system can process and analyze it.

1.2 Definition and classification of analog input module

Analog input module is a device specially used for analog signal acquisition and conversion. It usually consists of multiple analog input channels, each of which can receive an analog signal and convert it into a digital signal for processing. Analog input modules are classified according to the number of channels and accuracy, such as 8-channel, 16-channel, 12-bit or 16-bit precision.

2. Functional characteristics of analog input module
