Overview and Applications
Software
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.
All National Instruments PXI switch modules are shipped with
NI-SWITCH, an IVI-compliant driver offering complete
functionality for all switch modules. For additional assistance in
configuring, programming, and managing higher-channel-count
switching systems, NI Switch Executive software offers an easy-to-use,
intelligent switch management and visual routing environment.
Automatic Scanning
Ordering Information
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 61⁄2-digit FlexDMM, which issues a trigger after
each measurement.
