National Instruments 777690-01 Digital I/O Device
The part number 777690-01 from National Instruments is the identifying part number for the PCI-6503 Digital I/O Device. This device is designed for digital input / output operations with 24 lines of 5V TTL/CMOS logic levels compatible with the TTL. It supports handshaking for both input and output operations or bidirectional. This device is equipped with efficient data transfer techniques including the interrupt driven I/O and programmed I/O. With these techniques, it reduces the load on CPU by eliminating the need for constant polling and allows the system to respond quickly to real-time events.
The 777690-01 device has a maximum high logic voltage supply of 5 V with an absolute maximum voltage rating for each I/O line is −0.5 V to 5.5 V with respect to GND. It has input logic high voltage ranging from 2.2 V to 5.3 V while input logic low voltage ranging from −0.3 V to 0.8 V. Its output logic high voltage ranges from 3.0 V to 5.0 V at –2.5 mA and 2.7 V to 5.0 V at –4 mA while output logic low voltage range from 0 V to 0.4 V at 2.5 mA and 0 V to 0.5 V at 4 mA.
This module is designed to operate at an ambient temperature of 0 to 55 degrees Celsius and storage temperature of –20 to 70 degrees Celsius with a relative humidity of 5% to 90%, noncondensing. It is designed to be used for indoor use only and requires to be installed at an maximum altitude of 2,000 meters with a pollution degree of 2. The 777690-01 has a compact structure with physical dimensions of 12.2 cm × 9.5 cm (4.8 × 3.7 in.) and a weight of 55 g. It has a 50-pin male ribbon-cable connector allowing easy integrations into other digital devices and system.
This Digital I/O Device is compliant with several safety standards such as the IEC 61010-1, EN 61010-1, UL 61010-1, 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.
