Foxboro FBM219 (P0916RH) Discrete Input/Output Interface Module – Compact Digital I/O for I/A Series DCS

The Foxboro FBM219 (P0916RH) is a discrete input/output interface module for the I/A Series (200 Series) system, designed to handle digital signals where you need reliable status monitoring and simple on/off control. It’s typically used for things like pump run feedback, limit switches, proximity sensors, and driving interposing relays or valve solenoids. One thing I appreciate is how it combines discrete inputs and outputs in a single, compact FBM form factor, which helps when cabinet space is tight and you want fewer module types to stock.

Company’s Order Placement Process and Guarantees

• Warranty: 365 days
• Delivery time: In-stock usually ships in 1 week; no more than one month at the latest

Key Features

• Mixed discrete I/O in one module: Reduces module count and simplifies spare parts, especially in small cabinets.
• 24 VDC-level digital signals: Suited for typical plant instrumentation—status contacts, pushbuttons, relays, and solenoids.
• System-to-field isolation: Helps cut down on ground loops and improves noise immunity in electrically noisy areas.
• Redundant architecture friendly: Works within the I/A Series redundant Module Fieldbus so you can design for high availability.
• Hot-swappable: You can replace the module under power through the carrier—minimal process interruption when procedures are followed.
• Front-face LEDs: Quick visual check of module health and channel activity, which saves troubleshooting time.
• Standard 200 Series footprint: Fits existing baseplates and termination assemblies, so retrofit work is straightforward.

Technical Specifications

Brand / Model	Foxboro FBM219 (P0916RH)

Installation Method	Plugs into 200 Series baseplate; field wiring via Termination Assembly (TA)
Dimensions & Weight	Standard single-wide 200 Series FBM housing (compact footprint)
Operating Temperature	Typically 0 to 50 °C (per common FBM200 environmental range)
Isolation	System-to-field galvanic isolation (typical for FBM200 series)

Application Fields

From my experience, the FBM219 fits best where you have a mix of discrete signals clustered in the same junction boxes:

• Refining & petrochemicals: motor start/stop commands, pump run feedback, valve limit switches
• Power generation & utilities: breaker status, permissives, interlocks, solenoid actuation
• Water & wastewater: level switch inputs, blower control signals, local panel pushbuttons
• Pulp & paper / food & beverage: conveyor interlocks, jam sensors, bin level contacts

You might notice that combining DI/DO in one module often cleans up the BOM and shortens commissioning—fewer carrier slots and fewer TA variations to manage.

Advantages & Value

• Reliability: Works within the proven I/A Series redundant bus. Field isolation and status LEDs help with uptime.
• Compatibility: Native to Foxboro 200 Series baseplates and TAs; easy drop-in for brownfield upgrades.
• Cost control: Fewer module types to stock, simpler wiring, and less panel space usually means lower lifecycle costs.
• Supportability: Diagnostics at the module face and within the DCS reduce time to fault-find.

What customers say: “Swapping an FBM219 took minutes—hot swap, verify LEDs, and we were back. No surprises,” noted a maintenance lead at a Midwest chemicals plant.

Installation & Maintenance

• Cabinet & environment: Install on the 200 Series baseplate in a ventilated industrial cabinet (NEMA 12 / IP54 or better is typical). Keep within the module’s temperature range and avoid direct moisture.
• Wiring: Route field wiring to the appropriate Termination Assembly (TA). Separate high-voltage and low-level signal wiring. Use fused 24 VDC field power for DO loads and verify polarity.
• Grounding & shielding: Maintain a clean instrument ground. Shielded cable for long field runs can help in noisy areas.
• Redundancy: Where required, pair modules and follow the DCS redundancy guidelines to minimize single points of failure.
• Hot swap procedure: Place the channel in a safe state, confirm interlocks, then replace the module. Watch faceplate LEDs for healthy status before returning to service.
• Routine care: Periodic terminal checks for tightness, clean dust with dry air, and review system diagnostics. Firmware management is done through the I/A Series system, typically during scheduled outages.

Quality & Certifications

• CE marked; UL/cUL compliance is common for this series
• RoHS compliant electronics (typical for modern Foxboro modules)
• Manufactured under ISO 9001 quality systems (industry standard practice)
• Manufacturer’s standard warranty applies; our supply warranty is 365 days as stated above

Recommended Supporting Components

To make the most of FBM219, we typically ship with:

• 200 Series Baseplate/Carrier – for mounting and power/bus connectivity
• Termination Assembly (TA) – DIN-rail or panel TA options for field wiring, with fuse/relay accessories as needed
• Module Fieldbus Cables – for controller connectivity within the I/A Series rack
• Interposing Relays – when driving higher loads from discrete outputs
