Overview and Applications

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.

Automatic Scanning

The PXI-2568 is able to maximize throughput in automated test

applications by the use of scanning. Scanning improves throughput

by downloading a list of up to 32,000 connections to the switch and

cycling through the list using an event (trigger) without any

interruption from the host processor. Scanning is most efficiently

accomplished by mating the PXI-2568 with an instrument, such as

the NI PXI-4070 6

each measurement.
