FOXBORO FBM242
Product Introduction
Driving high-density discrete loads in an I/A Series system requires reliable switching capacity and channel isolation, and the delivers exactly that. Functioning as a 16-channel discrete output module, this unit provides isolated switching for relays, solenoids, and control valves directly from the DCS backplane.
Engineered for continuous industrial duty, the supports up to 0.5A per channel at 24V DC, making it suitable for both pilot-duty relays and direct solenoid actuation. The isolated channel architecture prevents ground loops and ensures that a fault on one output does not cascade to adjacent channels, maintaining system integrity in critical process environments.
Key Selling Points & Differentiators
- High-Density 16-Channel Output: Maximizes I/O density per baseplate slot, reducing panel footprint and backplane slot consumption for dense actuator and relay control applications.
- 0.5A Per Channel Capacity: Provides sufficient drive current for most industrial solenoids, pilot relays, and indicator lights without requiring external interposing relays.
- 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 module for analog control signals or high-current motor loads exceeding 0.5A per channel. For analog outputs, use the FBM230 series.
- 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 FBM baseplates. Verify your baseplate revision and node processor firmware first to ensure proper recognition. Send us your baseplate part number, and we’ll confirm compatibility within 30 minutes.
Can I use this module to drive motor starters directly?
No. The is rated for 0.5A per channel. Motor starters typically require higher inrush currents. Use this module to drive an interposing relay, which then controls the motor starter contactor.
Do I need to reconfigure the module after installation?
No. The retains its configuration in the I/A Series node processor. Simply plug it into the same slot, and the system will recognize it. However, always verify output assignments and safety interlock logic in your DCS configuration tool after replacement.
What if the module 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 a loaner program for critical control loops to minimize downtime.
Can this module handle high-interference environments?
Yes. The features channel-to-channel isolation designed to combat ground loops and electrical noise. However, ensure your field wiring uses properly shielded cable with correct grounding at the baseplate end to prevent induced transients.
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; 16-channel output activation test; node communication handshake test; 24-hour continuous load test; signed test report generated.
- Electrical Tests: Insulation resistance verified at 500V megger (>10 MΩ); ground continuity confirmed; channel-to-channel isolation validated.
- Firmware Verification: Firmware version recorded; DIP/jumper configuration backed up and documented.
- 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
- Overcurrent Damage: Risk: Output channel failure or module damage. Prevention: Verify load current does not exceed 0.5A per channel. Field Note: We’ve seen channels fail because a technician wired a solenoid with a 1.2A inrush current directly to the output. Always check load specs.
- Baseplate Seating: Risk: Intermittent output activation. Prevention: Ensure the module is fully seated and locked onto the baseplate. Field Note: A partially seated FBM caused random valve chatter during plant vibration. Push firmly until the latch clicks.
- Node Processor Compatibility: Risk: Module not recognized. Prevention: Verify the node processor firmware supports the revision. Field Note: Integrators waste hours troubleshooting when the real issue is a firmware gap. Check the revision first.
- Inductive Load Protection: Risk: Voltage spikes damaging output transistors. Prevention: Install flyback diodes or snubbers across inductive loads. Field Note: Missing flyback diodes on solenoid valves caused premature output channel failure. Always protect inductive loads.
- ESD Damage: Risk: Silent channel failure. Prevention: Use grounded wrist strap and anti-static mat during handling. Field Note: We’ve tested modules that passed power-on but had dead output channels after 48 hours due to ESD. Handle with care.
