Overview and Applications
The NI PXI-2575 and PXIe-2575 are high-density multiplexer switch modules.
With 196 one-wire channels or 98 two-wire channels, NI 2575 modules are
capable of routing hundreds of signals to measurement devices or from source
units. Each channel uses robust electromechanical relays and is capable of
switching up to 100 VDC/100 VAC or 1 A. With a scanning speed of up to
140 cycles/s, an NI 2575 acts as an effective front end for high-channel-count
automated test applications.
Software
All National Instruments PXI switch modules are shipped with NI-SWITCH, an
IVI-compliant driver that offers complete functionality for all switch modules.
For additional assistance in configuring, programming, and managing higher-
channel-count switching systems, NI Switch Executive software provides an
easy-to-use, intelligent switch management and visual routing environment.
Automatic Scanning
NI 2575 modules are able to maximize throughput in automated test applications
using 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. You can most
efficiently implement scanning by mating an NI 2575 with an instrument
such as the NI PXI-4070 6�½-digit FlexDMM, which issues a trigger after
each measurement.

Relay Count Tracking
NI 2575 modules count relay closures on each of their relays. Relay counts are
incremented each time a relay is actuated. You can programmatically retrieve
the counts, which are stored on board the modules, and use them for predictive
maintenance to reduce unexpected system downtime.
