National Instruments PCI-6225 Multifunction DAQ
National Instruments created the PCI-6225 (Part Number: 779295-01) data acquisition device for use in industrial automation applications. It provides an extensive feature set that is specifically designed to satisfy the needs of research, design verification/test, manufacturing test scenarios, and laboratory automation. The PCI-6225 offers dependable and affordable DAQ solutions with its analog I/O, digital I/O, counters/timers, and digital triggering capabilities.
Up to 40 differential or 80 single-ended channels with 16-bit resolution and a maximum sampling rate of 250 kS/s per channel are supported by the PCI-6225's analog input section. With its multiple input ranges (-10V to +10V), overvoltage protection, and high input impedance, it can measure a wide variety of signal types accurately and steadily. For analog output, the PCI-6225 offers two channels with 16-bit resolution and a maximum update rate of 833 kS/s. Reliable signal generation is ensured by its precise control over output voltages (-10V to +10V), low output impedance, and overdrive protection.
The digital I/O section consists of 24 channels individually programmable as input or output, with voltage protection up to ±20V. This makes it possible to seamlessly integrate external sensors and devices for increased system control and flexibility. Precise timing measurements and control functions, including frequency division, pulse generation, and edge counting, are made possible by two 32-bit counters/timers. In intricate automation settings, the counters/timers enable precise event recording and synchronization thanks to their numerous input possibilities and flexible routing.
The PCI-6225 also supports external digital triggers, allowing synchronization with external devices and triggering of analog input/output operations based on specific events or signals. The device can be seamlessly integrated into existing systems because it is compatible with PCI, PXI, and USB interfaces. By providing several data transfer modes—such as interrupts, DMA, and programmed I/O—it can increase data throughput and efficiency.
The PCI-6225 is now no longer available from NI (National Instruments), but the Multifunction DAQ will remain available for purchase or repair services in perpetuity with Apex Waves!
