FOXBORO FBM237 (RH914XS) is a channel-isolated, redundant-ready 8-channel analog output module, delivering 0-20mA signals for precise process control. Designed for industrial automation, it ensures high reliability with isolated outputs, fault detection, and hot-swappable redundancy support. Ideal for critical applications in oil & gas, power, and chemical industries, it integrates seamlessly with Foxboro’s I/A Series DCS for robust, fail-safe operation.
Product Specifications
Core Functionality:
Output Type: 8-channel, 0-20mA analog current output (isolated per channel).
Redundancy Support: Redundant-ready (1:1 backup) with automatic switchover for uninterrupted operation.
Isolation: Channel-to-channel & system isolation (1500V AC/DC minimum) to prevent ground loops and noise interference.
Performance & Reliability:
Accuracy: ±0.1% of span (typical) for precise control.
Update Rate: <50ms per channel for responsive output updates.
Fault Detection: Monitors open-circuit, short-circuit, and overload conditions, with LED/alarm indicators.
Hot-Swap Capable: Supports live insertion/removal without disrupting system operation.
Electrical & Environmental Specs:
Load Compliance: 0–750Ω (per channel) for broad device compatibility.
Power Supply: 24V DC (standard), with reverse-polarity protection.
Operating Temperature: -40°C to +70°C (industrial-grade durability).
Certifications: CE, ATEX (optional), IEC 61131-2 compliant for hazardous areas.
Integration & Compatibility:
DCS Integration: Native compatibility with Foxboro I/A Series distributed control systems.
Communication: Supports FOUNDATION Fieldbus or Foxboro’s proprietary protocols (varies by model).
Mounting: DIN-rail or panel-mounted (depends on carrier unit).
Typical Applications:
Process Industries: Oil & gas refining, chemical/petrochemical plants.
Power Generation: Boiler control, turbine management.
Water/Wastewater: Flow and pressure regulation.
Key Advantages:
Fail-Safe Redundancy: Ensures continuous operation in critical processes.
High Noise Immunity: Isolated design eliminates signal degradation.
Low Maintenance: Solid-state construction with diagnostic capabilities.
