Foxboro FBM201
Product Introduction
Backplane power integrity is the silent foundation of I/A Series reliability. The FOXBORO is a dedicated I/O bus power supply module that converts 220V AC input into the regulated DC voltage required by FBM carriers and the I/O bus. It sits at the heart of the cabinet, ensuring that every fieldbus module receives stable power regardless of load transients from adjacent cards.
This unit is a direct replacement for aging power supplies in legacy I/A Series cabinets. Field maintenance teams prioritize this exact model number because even minor revision changes can alter the current limiting thresholds, potentially causing nuisance trips or backplane undervoltage alarms during peak load conditions.
Key Selling Points & Differentiators
- Exact I/A Series Match: Designed specifically for FOXBORO I/A Series FBM carriers; not recommended for non-FOXBORO or third-party backplanes due to proprietary bus voltage regulation.
- 220V AC Native Input: Eliminates the need for external AC-DC converters, reducing panel footprint and potential failure points in the power distribution chain.
- Backplane Power Regulation: Provides stable DC output to the I/O bus, ensuring consistent FBM operation even during field device inrush currents.
- Rigorous Live Bench Testing: Every unit undergoes a 24-hour continuous load test with voltage ripple measurement and thermal monitoring 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
No. The is specifically designed for 220V AC input. Connecting it to a 110V source will result in undervoltage output and FBM communication failures. If your cabinet runs on 110V, you need the corresponding 110V variant (typically AD206HP or similar). Always verify your cabinet’s primary power rating before ordering.
I have an AD206HR on hand. Can I use it as a direct replacement?
The HQ and HR variants denote different hardware revisions or manufacturing batches. While they share the same base function, the internal current limiting and soft-start circuits may differ. I always recommend matching the exact suffix to avoid backplane compatibility issues. If you must substitute, verify the output voltage and current specs against your FBM carrier requirements first.
Do I need to configure anything before installing this power supply?
No. This is a purely analog power module with no firmware or configuration parameters. However, you should verify the output voltage with a multimeter before connecting it to the backplane. I always recommend checking the +5V and +24V rails against the I/A Series specification sheet before energizing the FBM carriers.
What happens if I install this without checking the backplane for shorts?
You risk immediate module failure. A shorted FBM or damaged backplane trace can draw excessive current, blowing the internal fuse or damaging the switching regulator. Always perform an insulation resistance test on the backplane before installing a new power supply. Use a 500V megger and verify >10 MΩ between power rails and ground.
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 voltage regulation results before installation.
