National Instruments PCI-6255 Multifunction DAQ

The PCI-6255 (Part Number: 779546-01) is a Multifunction DAQ designed by National Instruments. This device offers several features for computer-based systems in a single device. The PCI 6255 can fulfill many basic measurement requirements. DAQExpressTM companion software is provided in the PCI-6255 device. This software is used for basic measurement and analysis functions. The supported driver for the PCI-6255 is NI-DAQmx, which enables the device to design customized automated control application.

The PCI-6255 Multifunction DAQ has 40 differential analog channels as inputs. These inputs are programmable to be selected as single-ended. The input terminal is 16-bit resolution. The CMRR of the device is 100 dB. The maximum rate of sampling depends on the mode of input channels used. The single-channel mode has a rate up to 1.25 MS per second. For multichannel mode, the sampling rate is up to 750 kS/s. The NI PCI-6255 has an input voltage range of +0.1 V to +10 V. The bias current of the input is +100 pA. The NI PCI-6255 M Series DAQ has two 16-bit output analog channels, with a sampling rate of up to 2.86 MS/s. The impedance of the output channel is 0.2 Ω. The analog channels of this device are DC-coupled. 2 counters/timers–with a frequency of 80 MHz and a 32-bit resolution–are also installed in the device. The PCI-6255 I/O device also has 24 digital I/O channels. These channels are individually programmable. The digital channels have voltage protection of +20 V. The device is equipped with 2 68-pin VHDCI I/O connectors. It has power requirements of 0.03 A at +5 V, 0,725 A at +3.3 V, and 0.35 A at +12 V.

The PCI-6255 is suitable for various applications, such as research and industry applications. It is used in lab automation and manufacturing tests. This device is also used to verify and test new designs. The PCI-6255 supports SCC/SCXI signal conditioning modules. The engineers can add sensor reading options.

The NI device weighs 5.8 oz, and measures 3.8 x 6.1 in. in physical dimensions. It has a recommended operating temperature range of 0 ºC to 55 ºC, a storage temperature range of -20 ºC to 70 ºC.
