Key Features
- Multi-Mode Control:
- Closed-Loop Control: Uses PID algorithms with encoder feedback (1024 PPR) to achieve ±1.5 RPM accuracy at 1500 RPM, ideal for precision applications like medical equipment and test benches.
- Open-Loop Control: Relies on external speed signals (4–20 mA) for simpler systems like conveyors and fans, with ±0.5% accuracy.
- Load Adaptation: Detects sudden load changes (e.g., motor current spikes) and adjusts output within 50 ms to prevent speed drops (≤5 RPM deviation at 1500 RPM).
- Multi-Device Synergy: Seamlessly integrates with Siemens 6SE6440-2UD25-5CA1 inverters, Anchuan JAMSC-B2702V analog modules, and GE IC695ACC302 power supplies via Modbus RTU and RS485 interfaces.
- Diagnostics & Logging: Stores up to 50 fault events and 20 over-speed records with real-time timestamps for troubleshooting.
- Hot-Swappable Design: Modules can be replaced without powering down the system, reducing downtime.
Functional Highlights
- Speed Governance: Maintains stable generator speeds under fluctuating loads in power plants.
- Synchronization: Aligns phase and frequency for grid-connected or island microgrids.
- Startup Sequencing: Manages timed activation of auxiliary systems (e.g., lubrication pumps) during engine startups.
- Emergency Protection: Triggers fuel cutoff and mechanical braking within milliseconds upon detecting critical faults.
- Data Acquisition: Captures waveform data and trends for predictive maintenance.
Application Scenarios
- Power Generation: Controls generator speeds in thermal power plants, cogeneration units, and renewable energy systems (e.g., biomass, geothermal).
- Oil & Gas: Regulates centrifugal compressors and pump stations in production and transportation pipelines.
- Marine Propulsion: Manages main engine and auxiliary generator speeds on ships and offshore platforms.
- Industrial Automation: Optimizes motor speeds in manufacturing lines, mining equipment, and chemical processing plants.
- Transportation: Adjusts locomotive or generator set speeds for safe and efficient rail operations.
Advantages
- High Reliability: Designed for 24/7 operation in extreme conditions (vibration, shock, EMI).
- Scalability: Supports standalone systems or large-scale networks with hundreds of nodes.
- Ease of Integration: Compatible with third-party devices via Modbus RTU, reducing deployment complexity.
- Cost Efficiency: Minimizes downtime through proactive fault detection and remote diagnostics.
- Compliance: Meets international standards such as IEC 61508 SIL-2 and ATEX/IECEx for hazardous environments.
