FOXBORO FBM233
Product Introduction
Eliminating single points of failure in field communication is critical for maintaining continuous process visibility. The FOXBORO is a redundant Field Device System Integrator (FDSI) module engineered for the I/A Series DCS. Unlike simplex Ethernet cards, this unit features dual RJ-45 ports that connect to a network switch, integrating data from up to 64 external field devices directly into the Foxboro control database.
This module is designed to automatically detect communication path degradation and seamlessly swap roles between a master station and a tracking module. Field engineers rely on this hardware because it dynamically downloads specific I/O software drivers from a protocol library, ensuring robust integration of diverse third-party equipment without requiring custom hardware modifications.
Key Selling Points & Differentiators
- True Hardware Redundancy: Features dual 10/100 Mbps Ethernet ports with automatic master/tracking role swapping; not recommended for applications where simplex communication is acceptable.
- High-Density Device Integration: Supports communication with up to 64 field devices and 2000 DCI block connections via standard Ethernet switches or hubs.
- Dynamic Driver Architecture: Features a flexible hardware platform that allows specific I/O software drivers to be dynamically downloaded to match third-party device protocols.
- Rigorous Live Bench Testing: Every unit undergoes a 24-hour continuous load test with dual-port Ethernet communication verification and protocol handshake simulation before shipping.
- New Surplus Availability: Factory-sealed condition with verified source traceability, bypassing typical OEM lead times for discontinued I/A Series hardware.
- Anti-Counterfeit Verification: Serial numbers are checked against manufacturer databases during incoming inspection to guarantee authenticity.

FAQ
The is designed for the I/A Series platform, but compatibility with specific sub-platforms depends on firmware and backplane revision. Always verify your system’s exact configuration and check the I/A Series hardware compatibility matrix before ordering. Mixing incompatible FBM revisions can cause Ethernet communication failures.
No. The FBM232 (P0926GW) is a simplex module with a single Ethernet port, whereas the features redundant dual ports. Substituting a redundant module for a simplex one may require different termination assemblies, cabling, or configuration settings. Always match the exact model number to your application requirements.
Do I need to configure the IP address before installing?
Yes. The module utilizes an FDSI configurator to set XML-based port and device profiles. You must configure communication parameters such as DHCP or fixed IP addresses, as well as device-specific scan rates and data transfer volumes, before placing the module into service.
What happens if the primary Ethernet port fails?
The is designed to handle this exact scenario. If the I/O driver detects an issue with the master station’s port, it will automatically switch roles to the tracking module. You can also manually switch roles at any time through the SMDH interface to perform maintenance without dropping field communications.
Is there a warranty on this new surplus unit?
Yes. All new surplus modules come with a standard 12-month functional warranty. If the unit fails during normal operation within that period, we provide a direct replacement. We also include our internal test report with every shipment so you can verify the 24-hour load test and Ethernet communication results before installation.
