WOODWARD 8440-2028 Multi channel redundant control module
Specific parameters
Redundant architecture: TMR (Triple Redundancy)+1 hot standby channel, supporting seamless switching (switching delay ≤ 5ms)
Communication protocols: EtherCAT, OPC UA, IEEE 1588 time synchronization, compatible with Industry 4.0 environment
Input/output channels: 16 analog inputs (± 10V/4-20mA), 24 digital outputs (relay/transistor optional)
Working environment: -40 ° C to+85 ° C, optional high temperature or low temperature extension range, seismic grade IEC 60068-2-6 (10-150Hz, 5g acceleration)
Power supply design: dual independent 24V DC input+supercapacitor buffer (maintains continuous operation for 500ms after power failure)
Control mode: hydraulic drive, supporting proportional control or switch control
Input signal: Standard 4-20mA analog signal or digital control signal
Output torque: up to 20000 N · m (depending on specific configuration)
Work pressure: 10-20 MPa (typical value)
Response time: ≤ 100ms (from signal change to actuator response)
Protection level IP65/IP66 (dustproof and waterproof), optional explosion-proof certification (such as ATEX, IECEx)
Feedback device: Built in linear position sensor (LVDT) or rotary transformer, providing accurate position feedback
Installation method: flange or bracket installation, supporting multiple industrial standard interfaces
Product Performance
High precision control: using closed-loop control technology, the position accuracy can reach ± 0.1%, ensuring precise adjustment of valves or other control components. Support multiple control algorithms (such as PID) to adapt to complex working conditions.
Quick response: The hydraulic drive system provides high dynamic response capability, suitable for application scenarios that require quick adjustment (such as emergency shutdown, load changes).
Reliability and Durability: Made of high-strength alloy materials and sealed design, corrosion-resistant and vibration resistant, suitable for harsh industrial environments. The mean time between failures (MTBF) exceeds 50000 hours and the maintenance cycle is long.
Security feature: Supports fail safe mode (such as staying in place or returning to a safe position when power is off). Built in overload protection and temperature monitoring function to prevent system damage.
