FOXBORO P0926JM
Product Introduction
Building a reliable I/O infrastructure requires a foundation that guarantees deterministic communication and stable power delivery, and the is engineered to provide exactly that. Functioning as an 8-position modular baseplate, this chassis serves as the physical and electrical backbone for mounting Field Bus Modules (FBMs) within the I/A Series architecture.
Designed for continuous industrial duty, the integrates primary and secondary power inputs alongside dual fieldbus and time-gated interfaces. This robust backplane design ensures that up to eight FBMs operate with precise synchronization and uninterrupted data exchange, making it an essential component for critical process control in demanding manufacturing and energy environments.
Key Selling Points & Differentiators
- 8-Slot High-Density Mounting: Accommodates up to eight I/A Series FBMs in a single footprint, maximizing I/O density while minimizing control panel real estate.
- Dual Fieldbus Architecture: Features dedicated dual fieldbus and time-gated interfaces to ensure deterministic, real-time communication between the node processor and all connected FBMs.
- Redundant Power Routing: Equipped with primary and secondary power inputs to support redundant power distribution across the backplane, enhancing overall system availability.
- Verified Functionality: Every undergoes a 24-hour live load test on a dedicated I/A Series test rack before shipping, complete with a signed test report.
- Not Recommended For: Do not use this baseplate for non-I/A Series modules or as a standalone controller. It is strictly a passive backplane requiring a host node processor.
- Stock Availability: Current inventory is factory-sealed new surplus with traceable lot numbers; typically ships within 48 hours of order confirmation.
- Warranty Backed: Includes a 1-year functional warranty covering manufacturing defects and DOA conditions, with no restocking fees for verified failures.

FAQ
Yes. All units in stock have passed our 24-hour live bench test and include a signed test report. We ship same-day for orders placed before 2 PM EST, so you’ll have tracking before end of day.
The is designed for standard I/A Series 200 Series FBMs. However, verify your baseplate revision against your FBM hardware codes to ensure mechanical and electrical compatibility. Send us your FBM part numbers, and we’ll confirm compatibility within 30 minutes.
How many FBMs can I install in this chassis?
The supports up to 8 FBMs. Ensure your external power supply is adequately sized to handle the combined current draw of all installed modules plus a 20% safety margin.
Do I need to configure the baseplate after installation?
No. The is a passive backplane; it does not require software configuration. The I/A Series node processor automatically enumerates all FBMs plugged into the chassis during power-up. However, always verify slot assignments in your DCS configuration tool.
What if the baseplate fails within the warranty period?
We offer a no-questions-asked replacement for any verified manufacturing defect. Ship the failed unit back with your RMA number, and we’ll send a replacement within 24 hours of receipt. We also provide loaner chassis for critical I/O panels to minimize downtime.
Can this chassis handle high-interference environments?
Yes. The features robust backplane isolation and is built for G3 harsh environments. However, ensure the chassis is properly grounded to the panel ground bus and that all connected FBMs use shielded field wiring with correct grounding.
Is this a refurbished or new surplus unit?
This is New Original (New Surplus) – factory sealed, never installed, with full traceability to the original manufacturing lot. It is not refurbished, repaired, or pulled from a decommissioned system. We provide the original manufacturer’s lot code upon request for your quality records.
Quality Transparency SOP
- Incoming Verification: Source traceability confirmed via lot code; anti-counterfeit visual inspection; serial number cross-referenced with OEM records; accessories verified.
- Live Bench Test: Dedicated I/A Series test rack; power-on self-check; 8-slot FBM enumeration test; backplane voltage regulation validation; 24-hour continuous load test; signed test report generated.
- Electrical Tests: Insulation resistance verified at 500V megger (>10 MΩ); ground continuity confirmed; backplane power distribution validated.
- Firmware Verification: N/A (Passive backplane component).
- Final QC & Packaging: QC sign-off; anti-static seal applied; shock protection installed; QC Passed label affixed with date and inspector ID.
Test photos and video available upon request. We never claim “100% failure-free” – we provide verified, tested units with documented performance.
Technical Risk Avoidance
- Power Supply Undersizing: Risk: Backplane voltage drop, FBM resets. Prevention: Calculate total I/O current draw and verify the external power supply exceeds the chassis capacity by 20%. Field Note: We’ve seen baseplates fail to boot 8 FBMs because the power supply was undersized. Always calculate the load.
- FBM Slot Address Conflicts: Risk: Duplicate I/O, unpredictable behavior. Prevention: Verify FBM slot assignments in the DCS configuration match physical installation. Field Note: A technician moved an FBM to a new slot without updating the config, causing two valves to fight. Document slot changes.
- Backplane Seating: Risk: Intermittent FBM communication. Prevention: Ensure all FBMs are fully seated and locked onto the baseplate. Field Note: A partially seated FBM caused random channel dropouts during vibration. Push firmly until the latch clicks.
- Grounding Issues: Risk: Backplane noise, communication errors. Prevention: Verify the chassis is properly bonded to the panel ground bus. Field Note: A floating ground caused intermittent backplane faults that mimicked a bad FBM. Check your grounding scheme.
- ESD Damage: Risk: Silent backplane controller failure. Prevention: Use grounded wrist strap and anti-static mat during handling. Field Note: We’ve tested chassis that passed power-on but failed to enumerate FBMs after 48 hours due to ESD. Handle with care.
