Introduction
The Agilent U2600A series USB isolated digital input/output (DIO)
are high performance and user friendly modules. It can be used as
a standalone unit or as a modular unit. However, if used as
modular unit, the module needs to be installed in the U2781A
chassis. The U2600A series DIO consists of three models:
•U2651A: Isolated 32- bit DI and 32- bit DO
•U2652A: Isolated 64- bit DI
•U2653A: Isolated 64- bit DO
All three models have up to eight channels with 64- bit high
density isolated DIO. The high digital I/O lines will increase the
utility of the product and offer flexibility to the users.
The U2600A series DIO modules also equipped with high voltage
isolation protection of up to 1250 Vrms. This feature can protect
the instrument from severe damage to the internal circuit. The
product recognizes a wide range of digital input (10 V to 24 V) as
logic high. Therefore, it provides the users with more choices in
choosing the external sensors with different DC output level.
In addition, the U2600A series DIO modules has high output
driving capability of up to 35 V, which makes it capable to drive
most actuators in industrial automation applications. With the
Hi-speed USB connection of 480 Mbps, it is quick and easy to set
up the instrument.
The U2600A series DIO modules are compatible with a wide range
of Application Development Environments (ADE), such as Agilent
VEE, LabVIEW, MATLAB and Microsoft Visual Studio. Besides, a
special software, the Agilent Measurement Manager is bundled
with the U2600A series DIO modules for free.
