4. Functionality

The RIO-2018 functions as a remote thermocouple input and I/O control module that communicates over Ethernet using Modbus/TCP or HTTP/AJAX protocols. Each of the three thermocouple channels converts analog temperature signals into digital data using the MAX31855 converter with cold junction compensation, ensuring accurate readings across a wide temperature range.

The module’s built-in web server allows users to monitor temperature values, configure channels, and control digital outputs directly from a web browser without additional software. Through AJAX-based commands, users can fetch real-time data, adjust sampling rates (1–12 Hz), and toggle relay outputs.

In industrial automation systems, the RIO-2018 can be integrated with PLCs, SCADA, or IoT gateways for distributed temperature monitoring, process control, and alarm triggering. It supports Modbus holding registers for direct data exchange and can be accessed via RESTful web APIs for modern IoT applications.
