Application Fields and Application Cases
Core Application Fields
Typical Application Cases
- A large coal-fired power plant in North America: The analog input module of the boiler water supply control system in the plant’s Westinghouse Ovation DCS failed, resulting in inaccurate water supply flow monitoring. After replacing WESTINGHOUSE 5X00226G03, the signal acquisition accuracy was restored to ±0.1% FS, the anti-interference ability was significantly improved, and the system has been operating without fault for more than 10,000 hours, completely solving the problem of parameter drift caused by generic alternative modules.
- A European petrochemical enterprise: In the upgrade of the oil refining unit’s process control system, WESTINGHOUSE 5X00226G03 was adopted in batches as the core analog signal acquisition module. It perfectly matches the original Westinghouse PLC system, realizing multi-range signal acquisition and real-time transmission. The installation and commissioning cycle is shortened by 65% compared with using generic spare parts, and the monitoring accuracy of temperature and pressure parameters is increased by 30%.
- A Southeast Asian metallurgical plant: The blast furnace gas flow monitoring system of the plant used Westinghouse PLC for control. After selecting WESTINGHOUSE 5X00226G03 to replace the old analog module, the module’s excellent anti-interference and isolation performance effectively avoided signal crosstalk and interference in the metallurgical workshop, the data monitoring stability was greatly improved, and the blast furnace operation efficiency was increased by 15%.

Selection Suggestions and Precautions
Selection Suggestions
- If the on-site automation control system is Westinghouse Ovation DCS or original PLC system, WESTINGHOUSE 5X00226G03 is the first choice to avoid compatibility problems such as parameter drift and communication failure of generic modules, and ensure the stability of signal acquisition.
- For industrial scenes with high requirements for analog signal acquisition accuracy (such as power plant boiler control, petrochemical process monitoring), select WESTINGHOUSE 5X00226G03 for its ±0.1% FS ultra-high precision to meet the high-precision control requirements of the process.
- In the process of system expansion and signal acquisition capacity increase, select WESTINGHOUSE 5X00226G03 according to the on-site signal type (current/voltage) and range, and it can be flexibly configured without additional conversion modules, simplifying the system structure.
- For harsh industrial working conditions such as extreme high and low temperature, strong electromagnetic interference and high humidity, priority is given to WESTINGHOUSE 5X00226G03 with excellent environmental adaptability to ensure long-term stable operation of the equipment.
Precautions
- Before installation and commissioning, carefully read the original installation manual of WESTINGHOUSE 5X00226G03, and strictly follow the manual requirements for wiring and module installation. Cut off the on-site power supply before plugging and unplugging the module to avoid burning the module or damaging the control system due to live operation.
- When wiring, strictly distinguish the signal positive and negative poles, and avoid wrong wiring of power supply and signal lines. It is recommended to use shielded signal cables and connect the shield layer reliably to reduce electromagnetic interference and ensure signal acquisition accuracy.
- In daily maintenance, regularly clean the dust and dirt on the surface and pin contact of WESTINGHOUSE 5X00226G03. Cut off the power supply and use dry and dust-free compressed air to purge during cleaning to avoid poor contact caused by dust accumulation.
- When configuring the module, set the corresponding signal input range on the Westinghouse original configuration software according to the on-site actual signal type, and do not modify the original system parameters at will to avoid system misoperation.
- When storing spare parts, place WESTINGHOUSE 5X00226G03 in a dry, normal temperature, electromagnetic interference-free environment. The storage temperature is controlled at 0℃ ~ +35℃, and the relative humidity is ≤70% to avoid aging of electronic components and oxidation of pins.
- After replacing the module, carry out system no-load commissioning and signal calibration in turn, confirm that the signal acquisition value is consistent with the actual field value and there is no drift, and then carry out on-load operation to ensure the normal operation of the control system.
- It is strictly forbidden to use WESTINGHOUSE 5X00226G03 beyond the rated voltage, temperature and humidity parameter ranges, otherwise it will cause permanent damage to the module’s acquisition chip and reduce the service life of the module.
