Foxboro FBM203 P0914SV 8-Channel Isolated RTD Input Module – Multi-point, high-integrity temperature acquisition for Foxboro I/A Series systems
The Foxboro FBM203 P0914SV is the go-to RTD input module when you need stable, noise-immune temperature data from multiple points in a single cabinet slot. It handles eight isolated RTD channels and integrates natively with Foxboro I/A Series (and the modern EcoStruxure Foxboro DCS) via the standard 200 Series baseplate. From my experience, the channel-to-channel isolation is what keeps troublesome ground loops at bay, especially in larger plants where sensors sit far from the marshaling panels.
Our Order Placement Process and Guarantees

- Payment: 50% advance payment; full payment prior to delivery.
- Express options: FedEx, UPS, DHL.
Key Features
- 8 isolated RTD channels – Each channel is isolated, which typically reduces crosstalk and prevents ground loop issues across long cable runs.
- Direct RTD connection – Designed for standard industrial RTDs (commonly Pt100), 2- or 3‑wire, so you don’t need external transmitters in many cases.
- Tight integration with Foxboro I/A Series – Plugs into the 200 Series baseplate and communicates over the Foxboro Module Fieldbus for seamless engineering and diagnostics.
- High-density temperature input – Eight channels in a single-wide module saves cabinet space and simplifies wiring for multi-point temperature monitoring.
- Noise immunity and stability – Isolation plus robust input design helps retain accuracy in electrically noisy environments, like MCC rooms or near VFDs.
- Maintenance-friendly – Front-access terminals (via baseplate) and clear channel diagnostics make routine checks straightforward.
Technical Specifications

Application Fields
The FBM203 typically finds its place anywhere precise multi-point temperature feedback is critical:
- Oil & Gas and Petrochemical – reactor jackets, heat-tracing circuits, distillation column trays.
- Power Generation – bearing temperatures, lube oil skids, heat exchanger monitoring.
- Water & Wastewater – digester temperature, sludge drying, blower room monitoring.
- Pharma & Food – CIP/SIP temperature validation and controlled heating loops.
- Pulp & Paper – dryer sections and process tank temperature balancing.
You might notice that plants often replace scattered standalone transmitters with the FBM203 when they want uniform engineering, diagnostics, and alarming inside the DCS. It seems to be a cleaner lifecycle approach in many cases.
Advantages & Value
- Reliability – Isolated channels and robust Foxboro hardware typically boost uptime in electrically noisy areas.
- Compatibility – Native fit with 200 Series baseplates and I/A Series controllers reduces engineering hours and commissioning time.
- Cabinet efficiency – Eight inputs per module means less footprint and fewer terminal blocks compared to single-loop transmitters.
- Lower total cost – Direct RTD inputs can cut hardware spend and spares compared with distributed transmitters across the plant.
- Serviceability – Easy module swap on the baseplate; diagnostics help you pinpoint wiring or sensor faults fast.
Installation & Maintenance
- Cabinet environment – Mount on a Foxboro 200 Series baseplate within a ventilated control cabinet; keep within the stated temperature/humidity range.
- Power & grounding – Feed the baseplate with a clean 24 VDC supply; maintain a solid single-point ground to minimize noise.
- Wiring – Use shielded twisted pairs for RTDs; land 2‑ or 3‑wire leads per the channel diagram on the terminal assembly; separate from high‑voltage cabling.
- Commissioning tips – Verify RTD type (e.g., Pt100), wiring method, and scaling in the DCS. A quick loop check at ambient can catch inversions or open circuits.
- Routine checks – Inspect terminal tightness and cable shields periodically; perform sensor cross‑checks against a reference probe during planned outages.
- Firmware/config – Keep controller and system firmware current per site policy; document any range or filter changes in the instrument index.
Supporting components typically used with the FBM203: a 200 Series baseplate (DIN/panel mount), redundant baseplate power supply modules, and the matching terminal assembly for field wiring. If you’re consolidating panels, a slimmer baseplate can help fit eight or more FBMs in a single bay.
Quality & Certifications
- CE compliance for EMC and safety (typical for Foxboro 200 Series modules).
- UL/CSA certifications are commonly available for North American installations.
- RoHS conformity varies by hardware revision; we can confirm by serial/part code.
- Manufacturer-grade quality control with proven installed base in critical process industries.
Warranty support is 365 days through our channel. If you’d like, we can match the exact hardware revision to your controller firmware to avoid any compatibility surprises.
