Universal Input Connector
The Universal Input Connector
plugs into any open slot in the
2638A that contains a relay card.
The Universal Input Connector has
22 input channels (20 universal
inputs and 2 dedicated, low-burden
input current channels). Each input
connector contains a CJC (cold-
junction compensation) device,
which is calibrated at the factory.
The calibration date and input con-
nector serial number are programed
into the input connector and are
read by the 2638A when installed.
This information is saved in the test
setup data file, which is available
for review with any associated scan
data from a test setup. This feature
is a valuable form of traceability
if you are working in a regulated
industry.
Wiring a test or system setup
for 20 to 60 or more channels
can be time consuming. With the
inexpensive plug-in Universal
Input Connector, you can wire your
system once, quickly disconnect the
connector from your Hydra, then
reconnect the Hydra to another
input connector for use in a differ-
ent area.
Other data loggers require you
to wire your inputs directly to an
expensive “plug-in” active compo-
nent signal conditioning module.
If you need your instrument for
another test at another location,
you must remove your wiring or
use another expensive plug-in
signal conditioning module. With
Hydra Series III, all your signal
conditioning is inside the main-
frame, not in your input connector.
Using multiple low-cost Univer-
sal Input Connectors gives you the
flexibility to leave your input con-
nector at the test site, completely
wired, and ready to use. When you
need data from that site, simply
“plug in” and load your saved setup
file. It’s that simple!
Expandable channel capacity
Each 2638A has three slots in
the rear panel. Each slot can hold
a user accessible relay card and
a 22-channel Universal Input
Connector.
Three configurations are avail-
able, from 22 channels to 66
channels per mainframe. Select a
base model with 22 channels and
add 22-channel expansion kits
when needed. The low cost per
channel makes a 2638A a good
value for any budget.
Graphical color display with
easy-to-use menus
Never get lost again in a complex
menu tree while configuring chan-
nels or setting up a test. The large,
full color, thin film diode (TFD)
display enables the Hydra Series III
to display comprehensive easy-to-
understand data and easy menu
navigation.
Back-lighted function keys quickly
confirm the active menu selection.
The “Record” key illuminates to
indicate when the 2638A is recording
data in scan, monitor or DMM mode.
You always have visible confirmation
when your data is being recorded.
Copy-and-paste channel func-
tions make repetitive channel setups
a simple task. Top-of-screen menu
bar headings always let you know
where you are in the setup process.
View your data with the push
of a button. Page through all chan-
nel data and alarms in a quick view
mode or scroll through channels and
channel statistics individually. Statis-
tics include rate of change, min, max,
standard deviation, average, sample
size and peak-to-peak information.
