National Instruments 778966-01 Digital I/O Module
Part Number 778966-01 is the identifying part number for the National Instruments PCI-6511 Digital I/O Device. This device is a part of the NI 651x family of industrial digital modules. It is ideal for general-purpose data acquisition and control in industrial settings due to its high performance, high reliability, and ease of use.
The 778966-01 features 64 optically isolated input lines that can be used in a source or a sink configuration. This feature allows you to connect the device directly to industrial sensors and actuators. Likewise, the maximum input voltage that can be applied to the device is ±30 VDC while the maximum input current is 12.5 mA/line. Furthermore, the programmable power-up states allow you to configure the initial state of the digital I/O which means the output states never go through an incorrect state on startup. Moreover, the digital I/O watchdogs protect against computer crashes, operating system crashes, application crashes, driver crashes, and PCI bus failures by setting the output to a safe recovery state.
The 778966-01 works with the NI-DAQmx 7.2 driver, which is included free with the purchase of the module. NI-DAQmx technology generates code automatically, which accelerates development. You can program the module using a variety of programming languages like ANSI C, Microsoft Visual C++, and the Microsoft .NET languages C# and Visual Basic .NET and application development environments like LabVIEW.
The 778966-01 measures 5.94 in × 4.75 in. in physical dimensions and weighs 3.1 oz. Likewise, it features a 100-pin keyed female SCSI connector for I/O purposes. The device draws 150 mA at +5 VDC (±5%) and 300 mA at +3.3 VDC (±5%). The recommended temperature range for the operation of the 778966-01 is 0 °C to 55 °C at a relative humidity of up to 80% RH. Likewise, it can be stored at –20 °C to 70 °C. The device is only meant to be operated indoors up to a maximum altitude of 2000 m.
