RH916UK Foxboro Field Control Processor Foxboro Distributed Control System High Precision

The Foxboro RH916UK is a high-performance flow computer module designed for precision measurement and control in industrial automation systems. Part of Foxboro's legacy I/A Series Distributed Control System (DCS), this module integrates seamlessly into 19-inch racks for real-time processing of flow, temperature, and pressure data. Engineered for reliability, it features ruggedized construction with EMI/RFI shielding and operates in temperatures from -40°C to +70°C. The RH916UK supports complex calculations (e.g., AGA gas/diesel flow equations) and interfaces with field sensors via analog/digital I/O. Its modular design enables hot-swapping for minimal downtime, while embedded diagnostics ensure operational integrity in critical sectors like oil and gas, refining, and energy management.

• Inputs/Outputs: 16 analog inputs (RTD, mA), 8 digital I/O, 4 pulse inputs.
• Processing Speed: 32-bit RISC processor with 1 ms scan cycle.
• Flow Standards: AGA-3/8, API MPMS, NIST-compliant algorithms.
• Communication: Foxboro FOUNDATION™ Fieldbus, Modbus RTU/TCP, HART pass-through.
• Accuracy: ±0.01% of reading for flow calculations.
• Power Supply: 24 VDC (18-32 V range) with redundancy support.
• Environmental: Class I, Div 2/ATEX Zone 2 certified; 5-95% non-condensing humidity.
• Memory: 8 MB flash, 4 MB RAM for data logging.
• Certifications: CE, UL/cUL Class I, Div 2.

The RH916UK excels in fiscal metering and process optimization:

• Oil & Gas: Custody transfer monitoring, LNG flow measurement, pipeline SCADA.
• Refining: Crude allocation, flare gas quantification, tank farm inventory.
• Utilities: Steam/water flow balancing, energy consumption analytics.
• Chemical: Batch reactor feed control, additive dosing verification.
• Renewables: Biomass flow tracking, carbon capture efficiency audits.

Its robust architecture ensures compliance with ISO 6550/API 21.1 standards for legal metering, even in remote/unmanned sites.

1. Regulatory Compliance: Pre-certified for AGA/API fiscal metering, reducing audit risks.
2. Scalability: Modular expansion for up to 64 I/O points per chassis.
3. Cyber Resilience: Hardware-level security against unauthorized access.
4. Lifecycle Continuity: Backward compatibility with Foxboro I/A Series controllers (e.g., CP40/CP60).
5. Low TCO: Predictive maintenance alerts via FOUNDATION™ diagnostics extend mean time between failures (MTBF > 25 years).

• Multi-Variable Calculations: Real-time mass/energy flow, density compensation, and calorific value derivation.
• Data Integration: Seamless OPC DA/UA connectivity to historians (e.g., PI System) and ERP software.
• Alarm Management: Configurable thresholds with timestamped event logging (1,000+ records).
• Diagnostic Suite: Sensor drift detection, signal integrity checks, and communication health monitoring.
• Redundancy: Dual-redundant power and processor options for fault tolerance.
• Local Interface: Front-panel LCD for configuration without external tools.
