​​Application Scenarios​​

In a large coal-fired power plant,multiple​​Bailey INICT03A​​modules were deployed within the INFI 90 DCS to monitor critical boiler temperatures and pressures via hundreds of field transmitters.The modules’high channel density and individual channel isolation prevented ground loops and signal interference,ensuring highly accurate measurements that contributed to a 2%improvement in combustion efficiency and a significant reduction in emissions.The​​INICT03A​​’s reliability addressed the key pain point of maintaining signal integrity in an electrically noisy environment.

​​Technical Principles and Innovative Values​​

Innovation Point 1:High-Density Channel Isolation:The​​INICT03A​​provides individual isolation for each of its 16 input channels.This design prevents noise and ground loops from one field device affecting others,a significant advantage over modules with group isolation,ensuring data accuracy in complex industrial settings.

Innovation Point 2:Versatile Signal Conditioning:A key innovation is its ability to accept a wide range of analog signal types(4-20mA,voltage,etc.)without requiring external signal conditioners.This flexibility simplifies spare parts management and reduces system configuration time.

Innovation Point 3:Seamless INFI 90 Integration:The module is optimized for the INFI 90 system architecture,communicating efficiently over the node bus.This tight integration provides reliable,deterministic data transfer to the main controllers,which is crucial for real-time process control.

​​Application Cases and Industry Value​​

Case Study 1:A chemical processing plant used the​​Bailey INICT03A​​to monitor reactor temperatures and feed flow rates.The high accuracy(±0.1%)and stability of the modules enabled tighter control of the reaction process,increasing product yield by 5%and reducing off-spec material.The plant reported a direct annual savings of over$300,000,with the​​INICT03A​​modules operating flawlessly for over a decade.

Case Study 2:In a water treatment facility’s upgrade,existing​​INICT03A​​modules were seamlessly integrated with a new control platform.Their robust design and standard signal output minimized integration costs and downtime,demonstrating the long-term value and adaptability of the product.
