Description
The DAQPad-6508 Digital I/O Device, manufactured by National Instruments, is a high-performance data acquisition and control device designed for a multitude of applications. This device is notable for its versatility and efficiency, featuring a USB interface for easy connectivity.
It comes in various part numbers catering to different regional power requirements: 777661-01 for the US with 120 VAC, 777661-06 for the UK with 240VAC, and 777661-07 for Japan with 100VAC, ensuring global usability. The DAQPad-6508 is equipped with four 24-bit Programmable Peripheral Interfaces (PPIs), which are divided into three 8-bit subports, providing ample flexibility for complex configurations.
With an impressive transfer rate of up to 60 samples per second (S/s), it is designed to meet the needs of high-speed data logging, monitoring, and control applications. The device boasts 96 bi-directional 5 V static I/O lines, allowing for extensive data input and output capabilities. Furthermore, it can deliver an output signal current of 0.5A maximum at +5 VDC at pin-49 and pin-99, with a current drive of 2.5 mA per channel or 240 mA in total, suitable for driving a wide range of external devices.
Power requirements for the DAQPad-6508 are flexible, with an external power supply range of 9–30 VDC, consuming up to 12 W. Additionally, when powered via USB, it typically requires 220 mA and can go up to 500 mA maximum at 4.40–5.25 VDC. Its 100-pin female, 0.050 series D-type data connector ensures a reliable connection to external equipment.
The device also features a manual selection for wake-up state configuration, allowing users to set a high or low state with a 100 kΩ resistor connected with each terminal, offering further customization for various operational requirements. The DAQPad-6508 Digital I/O
