National Instruments 779005-02 C Series Digital Module

National Instruments part number 779005-02 is an identifying part number for the NI-9411, a C Series Digital Module. The NI 779005-02 has 6 Differential/Single-Ended Channels, a maximum Update Rate of 500 ns, and a Digital I/O Level between ±5 V to 24 V. It is compatible with industrial logic levels and signals, allowing for direct connection to various industrial switches, transducers, and devices. 

It is a correlated digital module, enabling correlated measurements, triggering, and synchronization when integrated into a CompactDAQ chassis. Within industrial environments, the part number 779005-02 may face interference, particularly when connected to peripheral devices or used in commercial or residential setups. To mitigate this interference and prevent performance issues, users should follow the instructions provided in the product manual during installation and operation. The digital module offers versatile connectivity options, allowing users to connect it to various devices such as external power supplies, differential devices, single-ended TTL devices, or encoders. 

Each channel of the module is equipped with I/O protection. While connecting an external power supply or other devices to the NI-9411 C Series Digital Module is optional, users can choose to do so based on their specific application requirements. Users can program the device using various software packages and application development environments (ADEs), including CompactRIO, CompactDAQ, LabVIEW Professional Development System for Windows, LabVIEW FPGA Module, and LabVIEW Real-Time Module. This can be identified by two part numbers. Part number 779005-02 does not have a conformal coating, whereas part number 779005-01 comes with a conformal coating. 

It allows for a maximum input voltage of 30 V channel-to-COM, safeguarding against potential overvoltage scenarios. Input current is internally limited to ±4 mA, protecting excessive current flow. Furthermore, the users must ensure that the product is not connected to circuits exceeding its continuous working voltage relative to earth or other channels, as this could compromise insulation and lead to damage.
