Overview

Product overview

Key product information and technical features.

The PCI-6120 combines simultaneous analog input acquisition with analog output, digital I/O and counter/timer functions on a PCI device. Its four differential inputs provide 16-bit resolution at a specified maximum sample rate of 800 kS/s per channel.

The device uses a PCI host connection and a SCSI-type front connection. The NI specifications, PCI getting-started guide and model-specific dimensional drawings provide resources for planning installation and signal connections.

Four differential analog inputs with 16-bit resolution and simultaneous sampling.
Maximum analog input sample rate of 800 kS/s per channel.
32 MS analog input FIFO buffer.
Two analog output channels with a specified maximum analog update rate of 4 MS/s.
Eight bidirectional digital channels and two counters/timers.
Bus-powered PCI interface with a SCSI-type front connection.
