FBM215 & FBM218 Basic Information Manufacturer: Foxboro / Schneider Electric System: I/A Series DCS & Evo Compact 200 I/O Module Type: 8-Channel Isolated HART Analog Output Module Model Definition FBM215: Standard Non-Redundant HART AO Module FBM218: Redundant Pair HART AO Module Common Specifications Channels: 8 galvanically isolated analog output channels Signal: 4–20mA DC + HART protocol compatible Isolation: Channel-to-channel & channel-to-ground isolation Withstand Voltage: 600 VAC 1 minute Resolution: 13-bit Accuracy: ±0.05% full scale Max Load: 750 Ω HART Speed: 1200 baud, 2 messages per second per channel Max HART Cable Length: 3030 m Power Consumption: ≤ 7 W Operating Temperature: -20°C ~ +70°C Storage Temperature: -40°C ~ +85°C Humidity: 5%–95% non-condensing Environmental Rating: ISA S71.04 Class G3 Certifications: CE, UL, ATEX, CSA Difference FBM215 Operation Mode: Single module, non-redundant Application: Ordinary non-critical control loops Termination Assembly: RH926SP / P0926SP FBM218 Operation Mode: Dual module hot redundant, automatic master/standby switch Application: Important critical loops requiring zero downtime Supports system-level redundancy and hot-swap replacement Key Features Each channel with independent HART modem for valve configuration, calibration and diagnosis. Full galvanic isolation reduces ground loop and field interference. Both modules support hot swap in corresponding system configuration. Industrial rugged design for long-term stable operation. Application Used for controlling HART valve positioners and 4–20mA actuators. Widely used in chemical, petrochemical, power, oil & gas and water treatment DCS systems.
