The National Instruments 778204-01 PXI Multifunction I/O Module, part of the PXI-6115 model series, is engineered to fulfill diverse industrial automation requirements. This multifunction data acquisition (DAQ) device excels in applications that demand synchronized capabilities for analog input (AI), analog output (AO), and digital input/output (DIO). It offers four simultaneous 12-bit analog inputs with a maximum sampling rate of 10 MS/s per channel, along with two 12-bit digital-to-analog converters (DACs) for high-performance voltage output generation. This integration is particularly advantageous for stimulus/response tasks, where precise synchronization among AI, AO, and DIO is critical.

Additionally, the 778204-01 features eight DIO channels compatible with TTL/CMOS logic levels, enhancing operations related to digital signal processing and control. It incorporates two 24-bit counters and a frequency scaler to support accurate timing measurements and pulse generation. Timing functions are managed through the NI data acquisition system timing controller (DAQ-STC), which consists of three timing groups that provide a maximum timing resolution of 50 ns, facilitating applications such as buffered pulse generation and equivalent time sampling.

The module utilizes the Real-Time System Integration (RTSI) bus, enabling seamless synchronization among multiple measuring devices. This capability improves system accuracy and reliability by better coordinating timing and triggering events. Designed for user convenience, the 778204-01 features software configuration and calibration that do not require physical adjustments such as switches or jumpers, enhancing ease of use. It is compatible with the NI-DAQmx driver and configuration software, and benefits from an extensive library of functions that streamline usage while ensuring a consistent software interface across various platforms.
