Data Acquisition Unit Development
Develop acquisition boxes around instruments and field equipment to complete channel configuration, protocol analysis, data caching and platform reporting.
Development Scope
Develop acquisition boxes around instruments and field equipment to complete channel configuration, protocol analysis, data caching and platform reporting.
4–20 mA / 0–10 V Analog Input Board Development
Design signal conditioning, protection, ADC interfaces and calibration procedures, then verify range, channel count, sampling rate and measurement error.

Information is used to determine interfaces, implementation conditions, and scope of work.
- 4–20 mA or 0–10 V signal type, range and number of channels
- Register table, device address, connection parameters and polling cycle
- Data rate, offline duration, and available storage capacity
Deliverables and Acceptance
- Delivery Documentation
- Schematic diagram, PCB, BOM, firmware and calibration records, conversion program, mapping configuration and device to platform integration testing records, cache module, configuration instructions and network and power outage test records.
- Versions and Reproducibility
- The delivery list records the target hardware, software version, build or deployment steps, interface configuration and test records to facilitate subsequent integration testing and maintenance.
- Record the collected value, reference value and absolute error at the agreed range point
- Check register to platform field conversion
- Check the integrity of records before and after offline according to the message sequence number
The acceptance is carried out based on the equipment, version, environment, samples and indicators confirmed by both parties; the scope of source code and design documents, prototype materials, third-party fees and subsequent maintenance are listed in the project documents.
Frequently Asked Questions
Can I delegate only one of the development modules?
Yes. 4–20 mA / 0–10 V Analog Input Board Development, Modbus-to-MQTT Protocol Gateway Development, Gateway Offline Buffering and Resumable Data Uploads can be scoped separately. Define the interfaces and integration responsibilities between modules before development.
Does ADC bit depth determine acquisition accuracy?
No. Acceptance measures errors across the complete acquisition chain, including the sensor, signal conditioning, reference source, ADC and calibration residuals. Resolution and actual measurement error are recorded separately.
