Core strengths
Real time computing capability: Equipped with a 32-bit processor and optimized bus, the control logic operation cycle is ≤ 10ms, suitable for high real-time requirements in power/petrochemical and other scenarios.
Redundant high availability: The hot standby redundant configuration ensures uninterrupted operation of the system in the event of a single module failure, meeting the reliability requirements of critical control systems.
Flexible communication adaptation: Multiple communication interfaces are compatible with protocols such as D.20 Link and Modbus, and can interface with I/O modules, SCADA systems, remote terminals, and adapt to distributed control architectures.
Comprehensive diagnostic mechanism: hardware self diagnosis+status indication+remote alarm, easy to quickly locate faults and reduce maintenance costs.
Modular compatibility: seamlessly integrated with D20 series I/O and power modules, supporting system expansion and upgrading, and adapting to the needs of projects of different scales.
Typical application scenarios
Power substation: As the core of substation automation, it controls the opening and closing of circuit breakers and transformers, processes telemetry/remote signaling data, connects protection relays, and ensures the stability of the power grid.
Petrochemical industry: The main controller of the DCS system for chemical plants, which executes logic such as temperature/pressure regulation of reaction vessels and flow control of pipelines, and links with on-site I/O modules to achieve closed-loop control.
Industrial automation: a centralized control unit for heavy-duty production lines, adapted to high temperature and high electromagnetic interference environments, ensuring continuous operation of the production process.
