The practical performance of FBM218 P0922VW in industrial sites

The practical performance of FBM218 P0922VW in industrial sites

Nov 22, 2025

² Foxboro, as a brand under Schneider Electric that has long served the field of process automation, focuses on the research and development and manufacturing of large-scale DCS (Distributed Control System) and its I/O modules, as well as communication interface modules. Its IA Series and Evo™ series products are widely used in industries such as petrochemical, chemical engineering, energy, and water treatment.

This module, FBM218 P0922VW, is a key component used in the Foxboro series control system, providing redundant output and HART communication capabilities.

 

² Today, as the global process industry accelerates towards "zero downtime and zero waste", Foxboro, a brand under Schneider Electric, announced that its star redundant output module FBM218 (model: P0922VW) has achieved over 500,000 hours of unplanned downtime operation in key facilities such as petrochemicals, power, and pharmaceuticals. With millisecond-level fault diagnosis, online life extension technology and full life cycle cost (LCC) optimization solutions, this module is becoming a win-win choice for "extending the life" of old DCS systems and "reducing costs" for new projects.

 

² FBM218 P0922VW - HART® Communication Redundant Output Interface Module.

This module is configured with 8-channel output, and each channel can be optionally equipped with a 4-20mA analog output or an analog output with HART® digital overlay. The module supports module-level redundant configuration (dual-module primary/standby), and performs optical isolation/transformer isolation on the channels, featuring high anti-interference capability.

In the future, with the deepening of industrial automation and digitalization, modularization, intelligence, and remote diagnostic capabilities will become key trends. Regarding the development direction of modules like FBM218:

Enhance digital communication capabilities: Although HART® communication is currently supported, more protocols (such as HART IP, FOUNDATION Fieldbus, Etherneta control) may be further integrated in the future to adapt to digital upgrades.

Integrated self-diagnosis and predictive maintenance functions: In the future, the module may have more self-monitoring functions (temperature, load, channel health status), and provide predictive maintenance suggestions through the system platform, thereby further reducing the risk of downtime.

Higher performance and higher density modules: As space and cost pressures increase, more output channels, smaller size, lower power consumption, and higher integration will become the trend in product design.

Life management and service model transformation: Manufacturers may offer "Module-as-a-Service" or "health status monitoring subscription" models, allowing users to maintain modules in the form of service packages and reducing capital investment.

Green energy conservation and environmental protection requirements: Industrial sites are increasingly emphasizing energy conservation and environmental protection. The power consumption of the module itself, material selection, and recyclability will become considerations for selection.

 

System Lifespan Extension: Rejuvenating "Old Devices"

Facing the I/A Series systems that were put into operation before 2000, FBM218 offers a "three no's" seamless upgrade package:

SIL 2/3 certified; existing safety matrix unchanged

 

In conclusion

The FBM218 P0922VW is a highly reliable redundant module provided by Foxboro for output communication with HART in process control systems. By thoroughly understanding its fault diagnosis methods, life extension strategies and cost control measures, enterprises can enhance system stability, extend service life and reduce operating costs. Looking ahead, with the development of the trend of industrial digitalization and intelligence, output interface modules will also be continuously upgraded
