Core Technical Characteristics & Performance Parameters
1. High-Performance Dual-Core Processing Architecture
Equipped with high-frequency embedded main CPU and professional 32-bit DSP processor, the module delivers powerful industrial computing performance. It achieves a Boolean instruction execution speed of 0.04 ms/K, supporting ultra-fast logic operation and fault response. Built-in 512 KB dedicated variable storage memory ensures stable caching and storage of operating parameters, fault records and real-time data. It can support the linkage operation of more than 256 local and remote I/O modules, meeting the complex logic control and large-scale data processing requirements of medium and large power systems.
2. Accurate Sampling & Reliable Protection Logic
The module supports high-precision collection and analysis of power voltage and current signals, with measurement accuracy up to ±1% full scale. It integrates mature power protection algorithms, realizing multiple protection functions such as overcurrent, overvoltage, undervoltage and phase sequence protection. It supports programmable relay output logic, with a maximum switching capacity of 5 A @ 250 V AC, which can stably drive on-site protection loops and accurately complete fault tripping and alarm output actions.
3. Multi-Protocol High-Speed Communication Capacity
Built with diversified high-speed communication interfaces, including dual Ethernet ports, RS-232 and RS-485 serial ports. It supports mainstream industrial and power communication protocols such as Modbus RTU, Modbus TCP, DNP3.0 and IEC 61850, and is fully compatible with GE EnerVista configuration software. The Ethernet port supports 10/100/1000 Mbps adaptive rate, realizing high-speed data interaction, remote parameter configuration, real-time status upload and fault information query with upper-level SCADA and DCS systems.
4. Advanced Redundancy & System Stability Design
Supporting PRP parallel redundancy protocol and N+1 CPU redundant backup mechanism, the module can realize seamless switching of master and standby controllers during system operation, effectively avoiding system shutdown caused by single-point failure. It matches the redundant power supply system of GE UR series chassis, further improving the overall operational reliability of the control system. It features powerful system compatibility, which can be seamlessly docked with all UR series I/O expansion modules, facilitating on-site system upgrade, function expansion and old equipment replacement.
5. Superior Electrical Protection & Anti-Interference Performance
Adopting industrial EMC electromagnetic compatibility and high dielectric isolation design, the module can resist strong electromagnetic interference, voltage surge and signal clutter in substation and power plant environments. Built-in complete over-voltage, under-voltage, over-current and short-circuit protection circuits, it can automatically trigger self-protection and fault isolation under abnormal electrical conditions. The optimized circuit layout effectively suppresses internal signal crosstalk, ensuring long-term accurate and stable operation of core computing and logic judgment functions.
6. Ultra-Wide Harsh Environment Adaptability
Designed for heavy-duty power industry working conditions, the module features an ultra-wide continuous operating temperature range of -40 ℃ to +85 ℃, adapting to extreme low-temperature and high-temperature working environments of outdoor substations and equipment cabins. The applicable ambient humidity is 5%–95% non-condensing, which can operate stably in high-humidity, dusty and temperature-alternating industrial scenarios. It supports long-term industrial on-site standby and continuous operation with strong environmental resistance.
7. Intelligent Diagnosis & Long-Term Operational Reliability
The module integrates comprehensive self-diagnosis functions, which can real-time monitor CPU operating status, communication link status, memory operation and power supply status. It can automatically record fault codes and operation logs, support one-click fault query and positioning, greatly reducing on-site operation and maintenance difficulty. It supports 24-hour uninterrupted S1 full-load continuous operation, adapting to the long-cycle uninterrupted operation mode of power generation and power supply equipment, with low failure rate and long service life.
