With support for multiple analog signal types (4-20 mA, 0-10 V, 1-5 V), the FOXBORO FBM208 eliminates the need for multiple specialized modules, reducing system complexity and hardware costs. It can directly connect to most mainstream field instruments without additional signal converters.
- Hot-Swap Capability for Uninterrupted Operation
The FOXBORO FBM208 supports online hot swapping, enabling maintenance teams to replace or upgrade the module during system operation. This feature is critical for continuous production processes in petrochemical and power generation industries, where unexpected shutdowns can lead to significant economic losses.
- Superior Anti-Interference Performance
Equipped with built-in EMI filters and isolation circuits, the FOXBORO FBM208 can resist strong electromagnetic interference from high-voltage equipment, motors, and variable frequency drives (VFDs), ensuring reliable operation in harsh industrial environments.
Application Cases in Application Fields
- Pharmaceutical Manufacturing
In a large-scale pharmaceutical plant in Europe, the FOXBORO FBM208 was deployed to collect analog signals from temperature and pressure sensors in drug synthesis reactors. The module’s high accuracy ensured that reaction parameters were monitored and controlled within strict tolerances, complying with GMP (Good Manufacturing Practice) standards and reducing product defect rates by 12%.
- Petrochemical Refining
A Middle Eastern refinery integrated the FOXBORO FBM208 into its DCS to monitor the pressure and flow of crude oil in distillation towers. The module’s anti-interference performance and hot-swap capability ensured uninterrupted data collection even in the high-noise, 24/7 operating environment, helping the refinery achieve a 99.9% equipment uptime rate.
- Water and Wastewater Treatment
A municipal wastewater treatment plant in North America used the FOXBORO FBM208 to process signals from dissolved oxygen (DO) sensors and pH meters. The module’s multi-signal compatibility allowed it to integrate with different types of sensors, enabling centralized control of the treatment process and improving water quality compliance rates.
