Description
The PCI-6255 is a PC-based Multifunction Data Acquisition (DAQ) device manufactured by National Instruments, designated with the part number 779546-01. This advanced DAQ device is well-suited for a wide range of applications requiring high-speed data acquisition and processing.
It features 40 differential analog input channels, which can be programmable to single-ended inputs, providing flexibility in connecting various sensors and signals. The device boasts a 16-bit resolution for precise data measurement and a Common-Mode Rejection Ratio (CMRR) of 100 dB, ensuring accurate readings by minimizing noise and interference.
The PCI-6255 offers a maximum sampling rate of 1.25 MS/s for single-channel operations and 750 kS/s for multi-channel operations, enabling it to handle high-speed signals effortlessly. The input voltage range is quite accommodating, from +0.1 V to +10 V, along with a bias current of +100 pA.
In addition to its impressive analog input capabilities, this DAQ device also provides 2 analog output channels with a 16-bit resolution and a maximum output speed of up to 2.86 MS/s. The output impedance of these channels is remarkably low at 0.2 Ω, which helps in maintaining signal integrity.
For tasks requiring precise timing and counting, the PCI-6255 is equipped with 2 counters/timers that operate at 80 MHz and offer a 32-bit resolution. It also includes 24 digital I/O channels, each of which is individually programmable, offering versatility in digital signal processing. These digital channels are protected against voltages up to +20 V, safeguarding the device from unexpected power surges.
Connectivity is facilitated through 2 x 68-pin VHDCI connectors, ensuring easy and secure connection to other devices and sensors. The power requirements for the PCI-6255 are modest, with +5 V at
