Data Sheet


The National Instruments PXI-2568 is a general-purpose 31-channel switch module, featuring independent SPST (Form A) armature relays. Each relay is latching with very low on-resistance and low thermal offsets. The NI PXI-2568 can switch up to 2 A at 30 VAC/30 VDC. With an efficient coupling of voltage/current capability and relay density, the PXI-2568 is ideal for automated test equipment (ATE) loads or for controlling heaters, lights, and fans.

Since your device does not have direct signal connectivity, you need a connector block to act as an interface between your sensors/signals and your device. A connector block provides easy access to the inputs and outputs of your hardware.
You need a cable to transmit signals between your device and your signal connections on your connector block.
You need software to interface with your hardware and to collect, analyze, present, and store your measurements. This board is compatible with a variety of programming languages, including LabVIEW, C/C++, Visual Basic, and .NET. LabVIEW provides the easiest integration with all of your NI hardware and is recommended to maximize your hardware investment.
