2. Core Technical Specifications & Features

2.1 Hardware Parameter Definition Function

1. Predefines field signal type, signal measuring range and current sourcing/sinking mode for analog I/O channels;

2. Hardware locks field wiring mode (2-wire/3-wire/4-wire), automatically activating lead resistance compensation for RTD/thermocouple temperature measurement loops;

3. Configures channel open-circuit judgment threshold, over-range alarm limit, fault fallback output value (hold last value / preset fixed value);

4. Enables or disables HART multiplex communication function at hardware level, matching HART intelligent field instruments.

2.2 Engineering Compatibility & Convenience

• After physical insertion, the main I/O module automatically identifies all configuration parameters upon power-on; no firmware upgrade, logic re-download or recalibration is needed on site;

• Same model modules support full universal interchangeability, greatly reducing spare parts inventory and management costs for power plants, petrochemical plants and other process enterprises;

• Applicable to new cabinet assembly, system capacity expansion, old equipment renovation and measurement loop modification projects of Ovation DCS.

2.3 Environmental & Reliability Indicators

• Operating Temperature Range: 0℃ ~ +60℃

• Storage Temperature Range: -40℃ ~ +85℃

• Relative Humidity: 5%–95% RH, non-condensing

• Complies with IEC 61000 series industrial EMC anti-electromagnetic interference standards, shockproof and vibration-resistant, adapting to long-term continuous cabinet operation environment;

• Service life cycle fully consistent with the whole set of Ovation control equipment.

2.4 Matching Diagnosis Function

• Cooperates with the main I/O module to realize loop fault detection, sensor disconnection alarm and communication anomaly diagnosis; fault codes can be uploaded to the upper controller via backplane bus for remote rapid troubleshooting;

• Does not occupy backplane bus bandwidth and will not affect the real-time refresh speed of closed-loop control loops.
