Description
INVENSYS P0926GX
Manufacturer: Foxboro (Invensys / Schneider Electric)
Part Number: P0926GX
Model Alias: FBM233
Product Type: Redundant Field Device System Integrator (FDSI) Ethernet Communication Module, I/A Series DCS
Product Overview
The P0926GX (FBM233) is a high-availability Ethernet field integration module for Foxboro I/A Series distributed control system. It serves as the bridge between the DCS controller and intelligent field devices over 10/100Mbps Ethernet, supporting redundant network architecture to eliminate single point of failure. It collects field device data, executes protocol conversion, and delivers real-time process information to the I/A control rack, widely used in high-reliability continuous process plants.

- Protocol conversion gateway function, allowing multiple intelligent Ethernet field instruments to connect to I/A Series DCS.
- Hot-swappable module design, can be replaced online without shutting down the entire control rack.
- Built-in comprehensive diagnostics: link status, communication timeout, module hardware fault detection.
- Supports multi-device polling, real-time data acquisition and alarm/event forwarding to DCS.
- Compact form factor, fits standard I/A FBM baseplate assembly, simple integration with existing I/A hardware.
Application Scenarios
- Petrochemical refining DCS control systems
- Power plant boiler and turbine control
- Pulp and paper continuous production
- Chemical process plants with large quantity of Ethernet smart transmitters and controllers
- Pharmaceutical batch control systems requiring high network availability
Installation & Maintenance Notes
- Install the module onto the matching FBM modular baseplate before wiring.
- Use shielded CAT5e Ethernet cable for field network; ground shield at single end to prevent ground loop noise.
- Configure IP address and device polling list via I/A Series engineering workstation.
- Verify redundant failover function during commissioning by disconnecting primary Ethernet link.
- Inspect LED status after power-up to confirm module health and network link quality.
- Backup module configuration before replacement or firmware upgrade.
