WOODWARD 8440-1849 D Dual redundant digital turbine control module
Specific parameters
Redundant architecture: dual independent control channels+cross check mechanism (CRC check cycle 1 μ s)
Communication protocols: ARINC 664 (Avionics Standard), Profinet IRT (Industrial Real time Ethernet), IEEE 802.1Qbv (Time Sensitive Network)
Environmental tolerance: -55 ° C to+125 ° C, anti electromagnetic interference 200V/m (MIL-STD-461F)
Sensor interface: 12 high-precision analog inputs (24 bit ADC, sampling rate 1MHz), supporting direct power supply for IEPE vibration sensors
Power supply design: Four redundant 28V DC inputs (main power supply+battery backup+supercapacitor+emergency generator interface)
Communication interface: Supports RS-232, RS-485, and CAN bus interfaces, can connect external I/O expansion units, supports CANopen and Modbus RTU protocols
Product Performance
Flexible conversion configuration: Open circuit, delay, and closed conversion transmission can be configured, and closed conversion transmission can be completed in less than 100 milliseconds.
Rich monitoring and testing functions: It has in-phase monitoring, load/no-load testing functions, and the interval of the engine trainer (load/no-load testing) program can be fully adjusted.
Multiple control modes: equipped with peak adjustment mode, load reduction function, and can select source priority. For cases where the closed conversion transmission time exceeds 100ms, there is a function to extend the parallel time.
Complete protection and indication functions: prohibit transmission and/or retransmission, with elevator pre transmission and motor load disconnection timer, event/alarm recording system, and real-time clock. Internal circuit breaker interlocking can be performed through discrete inputs to detect the position of the circuit breaker. Flexible configuration of discrete I/O, capable of detecting true RMS voltage, current, and power, with power availability and circuit breaker status indication.
Powerful logic function: Logics Manager provides programmable logic function, which can eliminate relay logic or PLC.
