Analog acquisition refers to analog signal input, which means that the input is a continuously changing physical quantity. Compared with digital input, digital input is simply 0 and 1, and current and voltage are two different ways to activate the input unit. The mainstream view is actually accurate. The more bits, the finer the analog quantization and the more accurate the result.

The functions of analog input/output modules used in other fields also include various acquisition functions, control functions, display functions, remote management functions, alarm functions and storage functions.

Chengdu YX-AI-004 is a high-precision analog acquisition module with an acquisition accuracy of 1‰. Built-in jumper range technology supports multi-range acquisition, 0-20ma, 4-20ma, 0-5V, 0-65, 438+00v and 0-30V acquisition to RS485 communication, Modbus RTU protocol and various configurations.
