2. Functional Features
High‑Performance Core Computing for Complex Process Control
Equipped with an industrial‑grade high‑frequency processor with powerful computing capacity, it efficiently handles complex closed‑loop regulation logic, batch sequence control, interlock protection logic and massive field point data. It precisely meets demanding process control requirements of thermal power, hydropower, new‑energy power stations and chemical plants with zero computing latency and logic jitter, ensuring process regulation accuracy and system response speed.
Redundant Bumpless Switchover for Elevated System Fault Tolerance
Natively supports dual‑controller hot‑standby redundant architecture with real‑time data synchronization and logic mirror backup between primary and standby controllers. Upon failure, power loss or abnormal offline of the primary controller, the standby module executes automatic bumpless switchover without process interruption, parameter jump or unintended equipment actuation. It eliminates system shutdown and production accidents induced by single‑point faults and satisfies high‑reliability fault‑tolerance standards for the power industry.
Multi‑Port High‑Speed Communication for Full‑System Architecture Compatibility
Integrated multiple high‑speed Ethernet communication interfaces supporting standard industrial Ethernet protocols, it seamlessly connects to Ovation control network, I/O subsystems, host monitoring systems and third‑party communication devices. It delivers high transmission rate, ultra‑low latency and robust data synchronization, enabling stable data interaction and command distribution across modules, cabinets and sites to guarantee coordinated operation of the whole system.
Fan‑Less Low‑Power Design for Zero Heat Accumulation during Long‑Term Operation
Adopting passive heat dissipation and fan‑less silent architecture without rotating wearing components, the module features low power consumption and uniform heat generation. It fundamentally avoids common risks such as fan aging, dust‑induced stalling and fault‑caused shutdown. Continuous long‑run operation achieves zero heat accumulation, zero power drift and zero performance degradation, greatly reducing module failure rate and daily maintenance costs.
Large‑Capacity Storage for Complex Program Solidification
Pre‑configured with large‑capacity flash memory and high‑speed operating RAM, it reliably stores system configuration programs, process control logic, interlock parameters, historical configurations and system firmware. It supports operation of complex control programs, multi‑point configuration and long‑period data buffering, satisfying high‑load control and computation demands of large‑scale industrial plants with multi‑loop and high‑precision requirements.
Industrial‑Grade Wide‑Temperature Anti‑Interference Capability for Harsh Operating Conditions
Built with industrial‑grade components and reinforced PCB technology, it tolerates temperature‑humidity fluctuation, dust accumulation and intensive electromagnetic interference in control rooms. With excellent immunity against voltage fluctuation, electromagnetic disturbance and temperature drift, it delivers stable long‑term performance in high‑risk continuous‑production sites of power and chemical industries and prevents computing anomaly, communication dropout and system error triggered by environmental factors.
Standard Original Compatibility for Commissioning‑Free Rapid Replacement
Fully compatible with native software‑hardware protocols, configuration logic and network architecture of Ovation DCS systems. Pin definition, communication parameters and computing logic match original systems completely. Failed legacy controllers can be directly replaced in‑situ without program reconstruction, re‑configuration or complex calibration to rapidly restore full‑load system performance.
