The Astronautics family of Data Concentrator Units (DCUs) is composed of modular analog-to-digital and digital-to-digital conversion devices that are tailored to specific avionics requirements. The DCUs are dual channel, fully redundant computers supporting real-time conversion of aircraft and engine sensor data into a digital format provided typically over ARINC-429 interfaces to Engine Indicator & Crew Alerting System (EICAS) displays, avionics computers and any other modern glass cockpit displays that requires engine/aircraft sensor data in a digitized form. ARINC-664 Remote Data Concentration is also available. The Engine DCUs interface with engine temperature, pressure and RPM sensors, providing digitization values of all engine, hydraulic & power plant sensors. The Engine DCUs converts all inputs into a digital format, conditions the signals and performs any required filtering and data conversion computation.
