It provides isolated DC power to both the module electronics and field devices, ensuring reliable operation of analog and digital I/O modules in critical process control applications. The redundant design includes two independent power supplies within a single module, with automatic failover if one side fails. The FBM216B P0927AJ mounts on a DIN rail and connects to FBM200 series modules via the fieldbus backplane. Status LEDs indicate power OK, fault conditions, and redundancy status. This unit is new surplus, factory-sealed in original Foxboro packaging. I/A Series components remain widely deployed in process industries; contact us for current stock and firm pricing. Frequently Asked Questions (FAQ) Q: What is the FBM216B, and where is it used in I/A Series systems? A: The FOXBORO FBM216B P0927AJ is a redundant power supply module specifically designed for FBM200 series fieldbus modules. In I/A Series DCS, FBM200 modules (analog input, analog output, digital I/O, etc.) require external power for both their internal electronics and field loops. The FBM216B provides this power with built-in redundancy. You’ll find it mounted next to FBM200 modules in I/A Series cabinets, powering everything from 4-20 mA loops to discrete sensors. Without it, the FBM200 modules don’t work. Q: What does “redundant” mean in the FBM216B design? A: The FBM216B P0927AJ contains two independent power supply circuits inside a single module. Both run simultaneously, sharing the load. If one side fails (due to component failure, surge, etc.), the other side instantly takes the full load with no interruption to the modules or field devices. An LED indicates the fault, so you know to replace the FBM216B at the next scheduled outage, but the process continues running. This is critical for continuous processes where downtime costs millions. Q: What input voltages does the FBM216B accept? A: The FOXBORO FBM216B P0927AJ is available in different input voltage variants. Common options include: 115V AC (standard US plant power) 230V AC (European/Asian) 125V DC (power plant battery systems) The specific variant is indicated by the full part number suffix. The P0927AJ typically denotes a standard AC version, but verify with your system documentation. Applying the wrong voltage will damage the module. Check your cabinet power before ordering. Q: What output voltages does the FBM216B provide? A: The FBM216B P0927AJ provides: 24V DC for field loops (4-20 mA transmitters, discrete sensors, valve positioners) 5V DC for module electronics Both outputs are isolated from each other and from input. The 24V field power is often used directly by two-wire transmitters, eliminating external power supplies for many loops. The 5V logic power runs the module’s internal circuits and communication. Q: How many FBM200 modules can one FBM216B power? A: It depends on the module types and field loads. The FBM216B P0927AJ has a rated total power capacity (check specific datasheet for exact wattage). Each module draws: Logic power (5V) from the backplane Field power (24V) for its channels High-power modules (like analog outputs driving I/Ps) draw more than low-power digital inputs. In typical configurations, one FBM216B powers 4-8 modules. For larger racks, you may need multiple power supplies or a higher-capacity unit. Always calculate your total load during system design. Q: What do the front panel LEDs indicate on the FBM216B? A: The FOXBORO FBM216B P0927AJ has multiple status LEDs: PWR A (green): Power supply A OK PWR B (green): Power supply B OK FAULT (red): Any fault condition (overload, overtemp, one supply failed) REDUND (green): Both supplies operating, redundancy active In normal operation, both PWR LEDs and REDUND are green. If one PWR LED goes out, that supply has failed—the FBM216B is still running on the other, but you need to plan replacement. If FAULT red appears, check for overload or impending failure. Q: Can the FBM216B be replaced online without shutting down the I/O? A: No. The FBM216B P0927AJ is a single module containing both redundant supplies. If it fails completely (both sides dead), all powered modules lose power—process I/O goes offline instantly. There is no hot-swap capability for this module. The redundancy protects against internal failure of one supply, but if the whole module must be replaced, you need a controlled shutdown of the powered modules. In critical plants, we keep spare FBM216B modules on hand and schedule replacement during outages. Q: What’s the typical failure mode for FBM216B modules? A: In my experience with I/A Series systems: Capacitor aging—after 10-15 years in warm cabinets, electrolytics dry out One supply side fails (redundancy works—other side carries on) Input surge damage—lightning or switching transients on AC/DC lines Connector corrosion in harsh environments (chemical plants, coastal) The FOXBORO FBM216B P0927AJ is robust, but nothing lasts forever. If you see one PWR LED out, the module is still running but degraded—schedule replacement. If FAULT appears with both PWR LEDs on, check for overload or impending failure. We proactively replace these at 15-year intervals in critical plants. Q: Does the FBM216B require configuration software? A: No. The FBM216B P0927AJ is hardware-only—no software configuration. It simply provides power. However, the I/A Series system monitors its status via the fieldbus backplane. The DCS can report power supply faults, redundancy status, and alarms to operators. This monitoring requires no configuration beyond standard I/A Series integration—the FBM216B reports its status automatically. Q: What’s the difference between FBM216B and FBM216? A: The “B” suffix indicates a hardware revision or enhanced version of the original FBM216. Typically, includes: Improved component selection Enhanced EMC protection Updated certifications Possibly higher output capacity The is the specific ordering code for this variant. Always match the exact part number from your existing system. Swapping a FBM216 for a usually works, but verify compatibility. In I/A Series, later revisions are generally backward compatible, but check your system documentation to be safe. Q: What maintenance does the FBM216B require? A: Minimal but important: Annual visual inspection for bulging capacitors, discoloration, or odor Check input voltage quality (sags and surges stress the supply) Verify both PWR LEDs are green during routine rounds Ensure cooling vents are clear of dust Check terminal connections for tightness (vibration loosens screws) The FOXBORO FBM216B is designed for long life, but preventive maintenance catches problems before they cause outages. In one refinery, we found a with one supply failed—still running, but degraded. Replaced it at next turnaround, avoiding potential failure mid-run. Q: Can I use a third-party power supply to replace the FBM216B? A: Absolutely not. The is specifically engineered for modules with: Correct voltage levels (5V logic, 24V field) Proper isolation and noise performance Mechanical fit in I/A Series cabinets Backplane communication for status monitoring A third-party supply will not match these requirements and could damage modules or cause erratic operation. In critical process control, use only genuine Foxboro modules.
