Overview
The Na ti onal In s tru m ents PXI-2570 is a 40-channel, genera l - p u rpose
switch module. Featuring independent SPDT (Form C) relays, the
NI PXI-2570 maximizes relay density in a single PXI slot. Each relay
contains a normally closed (NC), normally open (NO), and common
(COM) terminal and can handle up to 100 VDC/100 VAC or up to
1 A of current. With 40 channels per module, you can switch several
hundred ATE loads in a single PXI chassis or thousands of channels
in a multiple-chassis configuration.
Software
All National Instruments PXI switch modules are shipped with
NI-SWITCH, an IVI-compliant driver of fering com p l ete
functionality for all sw itch modules. For additional assistance in
con f i g u ri n g, progra m m i n g, and managing high er- ch a n n el - count
switching systems, NI Switch Executive software offers an easy-to-
use, intelligent switch management and visual routing environment.
Ordering Information
Automatic Scanning
The PXI-2570 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
c ycling thro u gh the list using an event (tri gger) without any
interruption from the host processor. Scanning is most efficiently
accomplished by mating the PXI-2570 with an instrument, such as
the NI PXI-4070 6
1
⁄
2
-digit FlexDMM, which issues a trigger after
each measurement.
