Digital I/O, D/A converter and
totalizer for your most common test
requirements
The L4452A combines digital I/O,
analog outputs and a gated totalizer
for your most common system control
needs.
The digital I/O supports output levels
up to 42 V. These channels can be
used with an external power supply to
control external devices or to sense
limit switch and digital bus status with
no complex handshake modes.
You can use the totalizer input to count
events. The digital inputs and totalizer
inputs may be included in a scan. Alarm
limits for the digital and event counter
inputs are evaluated continuously,
capturing and logging alarm conditions
even between scans.
The analog outputs can output up
to ±12 V or 10 mA DC with 1 mV of
resolution. They can be used to source
bias voltages to your device under test,
to control your analog programmable
power supplies, or use the outputs as
set points for your control systems.
External trigger capabilities make it
easy for you to time and synchronize
measurements and other events. This
can help you determine when to begin
or end a scan.

System connections you can trust
The L4452A comes with one heavy duty
50-pin Dsub connector that allows for
simple, reliable connection options.
Each connector uses 30 micro-inches
of gold to ensure a repeatable, accurate
measurement. Other connection
options include:
• Detachable terminal blocks with
strain relief
• Low-cost, standard 50-pin Dsub con-
nector kits and cables
• Mass interconnect solutions
Ethernet connectivity enables simple
connection to the network and remote
access to measurements
The Ethernet interface offers high-
speed connections that allow for
remote access and control. You can
set up a private network to filter out
unwanted LAN traffic and speed up the
I/O throughput, or take advantage of
the remote capabilities and distribute
your tests worldwide. Monitor,
troubleshoot, or debug your application
remotely. Ethernet communication also
can be used with the support of LAN
sockets connections.
The optional GPIB interface has many
years of proven reliability and can be
used for easy integration into existing
applications.
