Environmental Parameters
Operating Temperature: -25℃ to +70℃ (non-condensing environment, compliant with IEC 60068-2-1/2 standard)Storage Temperature: -40℃ to +85℃Relative Humidity: 5% to 95% (non-condensing, compliant with IEC 60068-2-3 standard)Protection Rating: IP20 (backplane itself, relying on overall cabinet protection)EMC Compliance: Meets EN 61000-6-2 (industrial environment immunity) and EN 61000-6-4 (emission limits) standardsVibration Resistance: 10-500Hz frequency range, 0.5g acceleration (sine wave), 30 minutes of continuous testing per axis
Product Performance
Efficient bus transmission: The 1.28Gbps high-speed serial bus enables microsecond-level data interaction between modules, supporting real-time data processing of 32K discrete I/O and 16K analog I/O, meeting the strict data transmission delay requirements of large-scale control systems.
Flexible expansion capability: The 9-slot design can simultaneously access 1 CPU module, 2 redundant power modules, and 6 I/O/communication modules; supports expansion to 1000+ I/O points via remote I/O links, adapting to control needs from small equipment to large factories.
High redundancy reliability: Supports hot redundant access of dual power modules, with automatic switching when a single power supply fails, switching time ≤10ms; the bus has a fault self-recovery function, and local link anomalies do not affect overall data transmission, with a mean time between failures (MTBF) ≥200,000 hours.
Excellent maintenance convenience: Modules support hot swapping, allowing replacement of I/O/communication modules without shutting down the system; built-in slot presence detection and fault diagnosis enable real-time viewing of each module’s status via the CPU module or HMI, with fault location time ≤5 minutes.
Strong environmental adaptability: The -25℃ to +70℃ wide temperature design covers alpine and high-temperature industrial scenarios (e.g., northern winter workshops, high-temperature chemical plant areas); vibration resistance and EMC design ensure stable operation in environments with dense high-power equipment.
