The National Instruments PCI-6220 is a versatile Multifunction Data Acquisition (DAQ) device from the M Series, designed to meet a broad range of application needs from laboratory automation to manufacturing testing and design verification. This model features 24 Digital I/O lines and 16 configurable Analog Input channels, which can be set as either 16 single-ended or 8 differential inputs, ensuring a high degree of flexibility. The device utilizes a single 68-pin VHDCI connector and operates with a 3.3 V signal environment. Enhanced performance is facilitated by six available DMA channels, which can be utilized for various input and output operations as well as timer/counter functions.

The PCI-6220 operates with specific power requirements, consuming 0.02 A at +5 V, 0.25 A at +3.3 V, and 0.15 A at +12 V under no-load conditions, with a maximum current limit of 1 A for the +5 V terminal to safeguard against potential damage. It is designed for indoor use and should be allowed a warm-up time of 15 minutes prior to operation. To ensure optimal performance, annual calibration is recommended, and it operates within a temperature range of 0 °C to 55 °C, although this can be extended to -20 °C to 70 °C while in storage. The physical dimensions of the PCI-6220 are 10.6 cm x 15.5 cm (4.2 in. x 6.1 in.), with a weight of 91 g (3.2 oz). It is important to note that while the PCI-6220 is in mature status, it continues to be available for purchase and repair through Apex Waves.
