The Foxboro FBM232 P0926GW is a ruggedized Field Bus Module from Schneider Electric’s Foxboro I/A Series system, designed for industrial network integration in harsh environments. This intrinsically safe module provides 16-channel analog/digital signal conditioning with 24-bit resolution, serving as the critical interface between field instruments and DCS/PLC systems. The FBM232 P0926GW supports simultaneous Modbus TCP and PROFINET communications, achieving 10/100 Mbps Ethernet data throughput with <1ms latency for real-time process control.
As part of Foxboro’s Platinum Line of field device integrators, the Foxboro FBM232 P0926GW features galvanic isolation up to 1500V AC between channels and built-in HART 7 pass-through capability. Its -40°C to +85°C operational range with IP67 protection enables deployment in offshore drilling platforms and cryogenic storage facilities. The module’s dual-redundant power inputs (18-32VDC) ensure continuous operation during voltage fluctuations.

Key Features and Advantages:
Multi-protocol flexibility: The Foxboro FBM232 P0926GW uniquely combines process automation protocols with IT-friendly Ethernet/IP communication, enabling seamless integration between legacy field devices and modern IIoT platforms. Its embedded web server provides real-time diagnostic data in OPC UA format.
Extreme environment resilience: Featuring conformal-coated PCBs and stainless steel connectors, this module withstands salt fog exposure (per ASTM B117) and 15G vibration (IEC 60068-2-6). The patented Thermal Equalization System maintains ±0.01% accuracy across 125°C temperature gradients.
Cybersecurity hardened: Integrated TPM 2.0 security chip with FIPS 140-2 Level 3 validation prevents unauthorized configuration changes. The module automatically generates encrypted audit trails compliant with NIST SP 800-171 standards.
Application Areas:
The Foxboro FBM232 P0926GW excels in:
- Chemical plants: Corrosive atmosphere batch process monitoring
- Water treatment: Chlorine gas detection system integration
- Mining: Explosion-proof conveyor belt sensor networks
- Food processing: CIP (Clean-in-Place) system validation
In offshore oil platforms, this module simultaneously processes drilling mud pressure sensors, flare gas analyzers, and emergency shutdown (ESD) systems while maintaining ATEX Zone 1 compliance.
