Core strengths
Redundant and highly available: Dual CPU hot standby architecture, fault free switching, suitable for high reliability requirements in key scenarios such as substations and petrochemical facilities.
Multi protocol compatibility: Supports mainstream industrial communication protocols, seamlessly integrates SCADA systems, IED devices, and third-party devices, and adapts to distributed control architectures.
Modular integration: Seamless integration with D20 series I/O and power modules through D.20 Link, supporting flexible system expansion and upgrading.
Precise control capability: The 32-bit processor ensures a control logic operation cycle of ≤ 10ms and can process multiple control loops in parallel to meet real-time control requirements.
Comprehensive diagnostic mechanism: Real time monitoring of hardware status, rapid feedback of fault information through indicator lights and alarm outputs, reducing maintenance costs.
Typical application scenarios
Power substation: As the core of 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 DCS system main controller executes logic such as reactor temperature/pressure regulation and pipeline flow control, and links with on-site I/O modules to achieve closed-loop control.
Industrial automation: adapted to high temperature and high electromagnetic interference environments, as a centralized control unit for heavy-duty production lines, ensuring continuous operation of the production process.
