Description
Product Description
FOXBORO RH926GH is a compression screw designed for Foxboro I/A Series termination assemblies (TA), serving as a critical hardware component for securing wire terminations in FBM (Fieldbus Module) systems, particularly for modules like FBM230 (P0926GU). FOXBORO RH926GH replaces the legacy P0926GH compression screw, offering enhanced durability and reliable wire retention for industrial wiring applications. FOXBORO RH926GH is made of high – grade corrosion – resistant alloy, ensuring stable electrical connections even in harsh industrial environments with vibration, temperature fluctuations, and chemical exposure. FOXBORO RH926GH is compatible with standard TA ring lugs (e.g., P0926PA) and terminal blocks, facilitating secure and consistent wire termination for both power and signal circuits in DCS fieldbus networks. FOXBORO RH926GH is easy to install and tighten with standard tools, reducing wiring errors and improving the overall reliability of field connections in I/A Series control systems. FOXBORO RH926GH is a genuine Foxboro (Schneider Electric) replacement part, ensuring compatibility and compliance with I/A Series system specifications.

Application Fields and Cases
FOXBORO RH926GH is widely used in process industries relying on Foxboro I/A Series DCS:
- Petrochemical Refineries: Secures fieldbus wiring for FBM230 modules in crude distillation and catalytic cracking units, ensuring reliable data transmission for process control.
- Power Generation Plants: Used in TA for boiler and turbine control systems, providing vibration – resistant wire termination for critical safety and monitoring circuits.
- Chemical Processing Facilities: Installed in corrosive environments to maintain secure connections for FBMs monitoring temperature, pressure, and flow in reactor systems.
Case Example: A North American chemical plant upgraded its aging I/A Series TA compression screws to FOXBORO RH926GH during a scheduled maintenance outage. FOXBORO RH926GH replaced P0926GH screws in 50+ TAs connected to FBM230 modules, eliminating intermittent signal drops caused by corroded or loose terminations. Post – upgrade, the plant reduced unplanned downtime related to wiring issues by 30% and improved control system stability, with no need for re – wiring or hardware modifications.
Comparison with Competing Products

| Drop – in Fit | Direct replacement for P0926GH | Requires thread/adapter changes | May need TA modification |
| Vibration Resistance | Industrial – rated clamping force | Low clamping force; prone to loosening | Moderate; inconsistent across batches |
| Warranty | Foxboro factory warranty | No warranty | Short – term (3–6 months) |
Selection Recommendations and Precautions
Selection Recommendations
- Choose FOXBORO RH926GH when upgrading/replacing P0926GH screws in Foxboro I/A Series TAs to maintain system compatibility.
- Match FOXBORO RH926GH with P0926PA ring lugs and FBM230 (P0926GU) for optimal termination performance.
- Order in bulk for large – scale maintenance projects to ensure consistent quality and cost efficiency.
Precautions
- Use the correct torque wrench to tighten FOXBORO RH926GH to Foxboro’s specified torque; over – tightening may damage threads or terminals.
- Store FOXBORO RH926GH in dry, anti – static packaging to prevent corrosion before installation.
- Do not mix FOXBORO RH926GH with non – genuine screws in the same TA, as this may cause connection inconsistencies.
- Inspect FOXBORO RH926GH for damage (e.g., stripped threads, corrosion) before installation to avoid wiring failures.
