The ProDAQ 3424 Function Card provides eight channel, each one equipt with an 24-bit Sigma-Delta Analog-to-Digital Converter with differential inputs and a maximum input range of +/-10.24V on a double wide function card. This allows for a total number of 32 fully differential input channels per VXIbus slot by fitting four ProDAQ 3424 function cards on a ProDAQ motherboard.

The front-end of the ProDAQ 3424 card provides the user with a flexible solution for a wide range of applications. A very useful feature is the possibility of selecting between either differential or single-ended input. For the single ended input the offset voltage from generated by the on-board DAC can be used to remove the DC voltage from the input signal and thus adjust the input range to the needs of the application. For calibration purposes, the input of every channel can be grounded or connected to the voltage output of the ProDAQ 3201 high-precision voltage reference.

The ProDAQ 3424 function cards provides source capabilities for ICP sensors as well as an interface for accessing Transducer Electronic Data Sheets (TEDS). This makes the card especially useful in vibration measurement applications.

ProDAQ modules provide compatibility with all current popular software environments and allow users to safely and simply expand their existing hardware and software systems.

The supplied driver automatically detects and initializes all function cards installed into a ProDAQ Motherboard Module, removing any possibility of configuration errors. The ProDAQ 3424 Sigma-Delta Function Card is supplied with VXIplug&play drivers for the WIN95 and WINNT frame-works.
