NELSco developed a specialized process controller for saffron processing machinery. Its dual-board architecture separates control and power, while operation logging supports process review and traceability.
A dual-board architecture separating control and power for enhanced reliability, with a 3.2" TFT touchscreen, RGB capacitive buttons, and an isolated relay board for equipment operation.
OTA update capability and operation-history logging with audio feedback for operator guidance and product-quality traceability.
The Challenge
Saffron processing requires precise, reliable control in an industrial environment, where power-board noise must not disturb the control logic, the operator needs a simple interface, and operation history must be recorded for quality traceability.
Our Approach
A dual-board architecture separated control and power for greater reliability. A 3.2" TFT touchscreen with RGB capacitive buttons provided the interface, an isolated relay board handled equipment operation, OTA update capability was added, and operation-history logging with audio feedback was implemented for operator guidance and traceability.
The Result
The result was a field-ready controller combining process control, operation-history logging, and remote firmware updates through OTA.
Results
- Precise automation and product-quality traceability
- Higher reliability via dual-board architecture and isolated relay
- Remote OTA updates and operation-history logging
