National Instruments 779205-01 Digital I/O Device

The part number 779205-01 from National Instruments is the identifying part number for the USB-6501 Digital I/O Device. This device is designed for simple control and monitoring capabilities. It is ideal for applications involving automated test equipment and data acquisition systems. This device is designed for digital input-output operations with 8 lines and allows the inputs and outputs to be configured that is software selectable. It has an output driver type of active drive or open collector that is also software-selectable.

The 779205-01 device has an absolute maximum voltage rating for each I/O line that is -0.5 V to 5.8 V concerning GND. It has an input logic high voltage ranging from 2.0V to 5.8 V while an input logic low voltage ranging from −0.3 V to 0.8 V. Its output logic high voltage ranges from 2.8 V to 3.6 V while the output logic low voltage is 0.4 V at  2 mA and 0.8 V at 8.5 mA.

This device is designed to operate at an ambient temperature of 0 degrees Celsius to 55 degrees Celsius with operating humidity of 5% to 90% RH, noncondensing and storage temperature of –40 to 85 degrees Celsius with a storage relative humidity of 5% to 90%, noncondensing. It is designed to be used for indoor use only and requires to be installed at a maximum altitude of 2,000 meters with a pollution degree of 2. The 779205-01 device has a compact structure with physical dimensions of 8.18 cm × 8.51 cm × 2.31 cm (3.22 in. × 3.35 in. × 0.91 in.) with the I/O connector and 6.35 cm × 8.51 cm × 2.31 cm (2.50 in. × 3.35 in. × 0.91 in.) without the connector. It has a weight of 84 g (3 oz) making it lightweight and easy to handle. It has a USB series B receptacle connector and 16 position screw terminal I/O connector.

The 779205-01 is compliant with several safety standards such as the  IEC 61010-1, EN 61010-1,  UL 61010-1, and CSA 61010-1 with electromagnetic compatibility including EN 61326 (IEC 61326) and  EN 55011, allowing this device to operate safely in industrial environments with challenging conditions without affecting the overall performance of the module.
