Problems solved by technology

In most application scenarios, the signals after signal acquisition and processing are transmitted through data lines. However, in many scenarios, many signal acquisition lines and power lines are distributed in the working area, which may not only cause interference to signal transmission , and the lines scattered under the feet will become unsafe factors, causing inconvenience and danger, resulting in the following shortcomings in the current signal acquisition system:

[0003] 1. Not compatible with 24V power supply system;

[0004] 2. Single-channel output control cannot realize real-time response of multi-channel signals, and cannot meet the requirements of multi-channel signal acquisition and processing in many application scenarios;

[0005] 3. The output driving ability is poor, the circuit structure is complex, the current gain is low, the load capacity is poor, and the operation is not stable and reliable.
