The ABB 07KR264dR1 is an advanced industrial control unit designed for high-performance process regulation in ABB MasterPiece 300 series Distributed Control Systems (DCS)—specifically optimized for large-scale industrial processes requiring complex control logic, high I/O capacity, and enhanced reliability. It functions as a "supervisory control hub," executing sophisticated control algorithms, coordinating with distributed I/O modules, and enabling seamless communication across the DCS network, while supporting redundant configurations for mission-critical applications. Below is its detailed specification:
- Product Model: 07KR264dR1
- Product Series: ABB MasterPiece DCS Control Units (High-Capacity Process Control, Advanced Redundancy)
- Core Function: Provides centralized control for large-scale industrial processes in MasterPiece 300 DCS; executes complex control strategies (multi-variable, model predictive control); manages high-density I/O networks; supports redundant operation with automatic failover; ensures data integrity and system availability in critical applications
- Control & Processing Specifications:
- Mechanical Specifications:
- Dimensions: 110mm (W) × 170mm (H) × 25mm (D) (MasterPiece 300 rack-mount)
- Mounting Type: Dedicated high-capacity slot in MasterPiece 300 rack (uses redundant backplane connections)
- Housing Material: Aluminum-reinforced FRP (UL 94 V0, EMI-shielded)
- Weight: Approximately 350g
- IP Rating: IP20 (control cabinet installation, compatible with MasterPiece 300 enclosure)
- Environmental Ratings:
- Operating Temperature Range: -5℃~+65℃ (23℉~149℉)
- Storage Temperature Range: -25℃~+75℃ (-13℉~167℉)
- Humidity Tolerance: 5%~95% RH (non-condensing, 50℃)
- Vibration Resistance: 10~500Hz, 1g acceleration (IEC 60068-2-6)
- Shock Resistance: 20g (11ms half-sine, IEC 60068-2-27)
- Compliance Standards: CE, RoHS, IEC 61010-1, EN 61326-3-1, UL 508, ABB MasterPiece 300 Compatibility, IEC 61508 (SIL 2 capable)
- High-Capacity Control Processing: Dual-core 200MHz processor supports 256 concurrent control loops—handles large-scale processes (e.g., petroleum refineries, multi-zone chemical plants) with complex interactions between variables, eliminating the need for multiple lower-capacity controllers.
- Advanced Control Algorithms: Includes Model Predictive Control (MPC) and fuzzy logic—optimizes multi-variable processes with coupled parameters (e.g., temperature/pressure in distillation columns), reducing energy consumption by 15-20% compared to standard PID control.
- Redundant Architecture: Supports 1:1 hot standby redundancy with <50ms failover—automatically switches to backup unit during faults, ensuring uninterrupted operation in safety-critical applications (e.g., nuclear power auxiliaries, hazardous material processing).
- High-Speed Backplane Integration: 1Gbps connection to MasterPiece 300 backplane—manages 1000+ I/O points with minimal latency, enabling real-time control of distributed field devices (sensors, actuators) across large industrial facilities.
- Enhanced Data Logging: 8GB internal storage for process history—records 1000+ parameters at 1-second intervals for up to 30 days, facilitating detailed trend analysis, troubleshooting, and compliance reporting (e.g., EPA, OSHA requirements).
- Dual Redundant Ethernet: Two independent Ethernet ports with automatic failover—ensures continuous communication with DCS operators and enterprise systems, critical for maintaining situational awareness in large-scale operations.
- SIL 2 Capability: Complies with IEC 61508 for Safety Integrity Level 2—suitable for control applications where failure could lead to minor safety incidents, reducing the need for separate safety controllers in mid-risk processes.
- Large-Scale Process Industries: Primary use for complex operations:
- Petroleum Refining: Controls distillation columns, catalytic crackers, and hydrotreaters—MPC algorithms optimize yield across interconnected units, maximizing production of high-value products (e.g., gasoline, jet fuel) while minimizing energy use.
- Chemical Manufacturing Complexes: Manages multi-reactor sequences and material transfer systems—coordinates batch and continuous processes across large facilities, ensuring consistent product quality and efficient material utilization.
- Power Generation Facilities: Regulating critical systems:
- Thermal Power Plants: Controls boiler combustion, turbine speed, and generator output—redundant operation ensures continuous power production, while advanced control minimizes emissions (NOx, SO2) to meet environmental regulations.
- Combined Cycle Power Plants: Optimizes gas turbine and steam turbine coordination—MPC algorithms balance fuel consumption and power output, improving overall plant efficiency by 2-3%.
- Water & Wastewater Utilities: Managing large distribution networks:
- Municipal Water Treatment: Controls filtration, disinfection, and pumping systems across regional water facilities—coordinates operations between multiple treatment plants to maintain consistent pressure and water quality in distribution networks.
- Industrial Wastewater Processing: Regulates pH neutralization, biological treatment, and sludge handling—handles variable inflow conditions with adaptive control, ensuring compliance with discharge permits.
- Mining & Metals Processing: Controlling resource extraction and refinement:
- Mineral Processing Plants: Manages crushing, grinding, and flotation circuits—optimizes reagent dosing and equipment speed to maximize mineral recovery while minimizing energy consumption.
- Steel Production: Controls blast furnace temperature, oxygen flow, and casting speed—sequential logic coordinates multi-stage processes, ensuring consistent steel quality and reducing scrap rates.
