Description
The FOXBORO FBM203 P0914SV is an 8-channel isolated Resistance Temperature Detector (RTD) input module from the Foxboro I/A Series 200-Series fieldbus family, designed for precise temperature measurement in process control systems. It connects to platinum, nickel, or copper RTD sensors via 2-, 3-, or 4-wire configurations and provides galvanic isolation between channels to ensure reliable data in noisy industrial environments. The module mounts on a standard 200-Series baseplate and communicates digitally with its associated controller over a redundant 2 Mbps module fieldbus.
Product Parameters
FBM203 P0914SV features eight independent input channels, each supporting a resistance range of 0 to 320 ohms (mapped to 64,000 counts for high resolution). It handles common RTD types including Pt100, Pt1000, Ni100, and Cu10 sensors, with automatic lead compensation for 3- and 4-wire setups to minimize wiring errors. Power is drawn from the baseplate backplane (typically 24 V DC nominal), with consumption under 10 W total. Each channel offers configurable filtering (low-pass options from 1-60 Hz), diagnostics for open/short circuits, and burnout detection. The module weighs approximately 0.55 lb (249 g), measures 102 mm high x 45 mm wide x 104 mm deep (excluding terminals), and operates from -40°C to +70°C with 5-95% non-condensing humidity tolerance.

Datasheet Overview
Key datasheet specifications include channel isolation rated at 250 V RMS channel-to-channel and to ground, input accuracy of ±0.1% of span (typical), and linearity within ±0.05% across the full range. Update rates reach 100 ms per channel in fast-scan mode, with resolution equivalent to 0.016°C for Pt100 sensors. Front-panel bicolor LEDs indicate module health (green=OK, red=fault) and fieldbus status. It pairs with termination assemblies like P0916AE for screw-terminal field wiring, supporting up to 16 channels per paired assembly. Compliance covers EMC (EN 61326-1), safety (IEC 61508 SIL 2 capable), and vibration/shock per IEC 60068-2 standards. Firmware is field-upgradable via the fieldbus, and HART passthrough is not supported (RTD-only).
Origin
Foxboro FBM203 modules originate from manufacturing facilities in the United States, reflecting Foxboro’s (now Schneider Electric) heritage in process automation production centered in North America.
