Description
The 779066-01 and 779418-01 part numbers refer to devices within the M Series offered by National Instruments. These devices are designed as Multifunction I/O Devices, showcasing a versatile range of capabilities suitable for various application needs.
With regard to analog inputs, these devices are equipped with 16 single-ended or 8 differential channels, providing flexibility in connection types. The analog input resolution stands at 16 bits, ensuring precise data capture. Furthermore, they boast a data acquisition rate of 250 kS per second, allowing for efficient and rapid data collection.
On the analog output front, there are 2 channels available. The analog output rate varies depending on the usage; it can achieve up to 833 kS per second on a single channel or 740 kS per second when both channels are used simultaneously. This demonstrates the device’s capability to handle high-speed data output tasks.
These devices are designed to be bus powered, compatible with either 3.3 V or 5 V signal environments, making them adaptable to various system configurations without the need for an external power source.
The analog input absolute accuracy is specified at 3100 uV, indicating the precision level of measurements the device can achieve. Despite the high data acquisition rate of 250 kS per second, it is noted that simultaneous sampling is not supported, which may influence the choice of device based on specific application requirements.
Additionally, the inclusion of 2 32-bit counter/timers enhances the device’s utility in applications requiring precise timing or counting functions. The digital I/O (DIO) capabilities vary based on the connector version; the 68-pin version supports up to 8 correlated (clocked) DIO channels up to 1 MHz, while the 37-pin version supports 2 correlated (clocked) DIO channels, demonstrating flexibility in digital interfacing.
