National Instruments 779085-01 Digital I/O Device

Part number 779085-01 is the identifying part number for the National Instruments PCI-6519 Digital I/O Device. This device is a part of the NI 651x family of digital I/O interfaces that are commonly used for general-purpose data acquisition, industrial control, and manufacturing test applications. 

The 779085-01 features 16 input channels that can be configured either in the source or the sink mode. Likewise, it also has 16 output channels operating only in the sink mode. The maximum input voltage supported by the module is 30 VDC. The input logic low voltage level is 0 VDC (min) to ±4 VDC (max) whereas the input logic high voltage is ±11 VDC (min) to ±30 VDC (max). The maximum input current for 11 V and 30 V inputs 
is 4.5 mA/line and 12.5 mA/line respectively. The propagation delay for the inputs is typically 75 µs. 

The current output for the 779085-01 is temperature dependent: 475 mA up to 25 °C, 425 mA up to 35 °C, 375 mA up to 45 °C, and 325 mA up to 55 °C. The power-on state is user-programmable to 0 or 1 and it sits on 0(open) as default. The propagation delay is 80 µs while the programmable power-up states response time is 400 ms. 

The power consumed by the 779085-01 is 250 mA (typical) at +5 VDC (±5%) and 300 mA (typical) at +3.3 VDC (±5%). The module measures 5.54 in. × 4.47 in. in physical dimensions and weighs 2.5 oz. A 37-pin male DSUB is used as a connector. 

The recommended temperature range for the operation of the 779085-01 is  0 °C to 55 °C  at a relative humidity of up to 10% to 90% RH. Similarly, the device should only be utilized inside, up to a maximum elevation of 2000 meters. On the other hand, it can be stored at–20 °C to 70 °C. The device meets the following safety standards for electrical equipment for measurement, control, and laboratory use: IEC 61010-1, EN 61010-1, UL 61010-1, 
and CSA 61010-1.
