Title | Programmable Discrete I/O System |
---|
Description | This application note describes the design of a universal discrete I/O system with 24 programmable outputs and 24 programmable inputs, easily modifiable to match specific customer system requirements. It is designed to operate with a standard 28 VDC aircraft power supply and uses several Holt IC devices that interface to GND/Open and Supply/Open sensors and provide 28V current source and current sink load drivers. |
