CR9000XC
The CR9000XC is a compact version of the CR9000X. The CR9011
Power Supply Module, CR9032 CPU Module, CR9041 A/D and Ampli-
er Module, ve I/O module slots, one 7 Ah sealed rechargeable bat-
tery, and an environmental enclosure are included with the purchase
of the CR9000XC.
Transient Protection
Rugged gas tubes protect all terminal block inputs and outputs from
electrical transients. The CR9000X series is CE compliant under the Euro-
pean Union’s EMC Directive, meeting ESD, EMC, Fast Transient standards.
I/O Modules
A mix of I/O modules is selected based on the measurements re-
quired for the application. Individual I/O modules can be “swapped
out”, allowing the system to be recongured if requirements change.
I/O modules whose model numbers end in an E (e.g., CR9051E,
CR9055E) and the CR9052DC include an easy connector module.
CR9051E Analog Input Module
The CR9051E provides 14 dierential (28 single-ended) input chan-
nels for measuring voltages up to ±5 V. Resolution is 1.6 µV on
the most sensitive range. This module has an on-board reference
PRT and connectors for precise thermocouple measurements. The
CR9051E channels are fault protected to +50 V/-40 V. This prevents
overvoltage on one channel from corrupting measurements on
other channels. The CR9051E channels become open circuits when
the datalogger is powered down so sensors are not loaded.
CR9052DC and CR9052IEPE Anti-Alias Filter and
Spectrum Analyzer Modules
The CR9052DC is a high-performance anti-alias lter and Fast Fourier
Transform (FFT) spectrum analyzer with dc excitation. The CR9052I-
EPE module provides excitation and signal conditioning for IEPE-type
(Integral Electronic Piezo Electric) accelerometers, microphones, and
pressure transducers. Detailed information and specications are
available in the CR9052DC and CR9052IEPE brochure.
CR9055 or CR9055E 50-Volt Analog Input Module
The CR9055(E) has 14 dierential (28 single-ended) programmable
input channels for measuring voltages up to ±50 V. Resolution to
16 µV is available.
CR9058E Isolation Module
The CR9058E provides 10 isolated dierential channels for measuring
thermocouples or other low level voltage measurements that are at
an elevated voltage plane. Each channel has its own isolated ground
for shielded cable connection, and its own 24-bit A/D converter that
supplies input isolation for up to ±60 Vdc. An on-board digital signal
processor provides digital noise ltering that is automatically maxi-
mized for the specied integration time. For precise thermocouple
measurements, the CR9058E includes an on-board reference PRT.
CR9060 Excitation Module
The CR9060 provides six continuous analog outputs (CAOs), 10
switched excitation channels, and eight digital control outputs. The
CAOs have individual digital-to-analog converters for proportional
control, waveform generation, and excitation. Each CAO sources up
to 50 mA between ±5 V. The excitation channels provide preci-
sion voltages for bridge measurements. The digital outputs control
external devices.
CR9071E Timer/Pulse Input Module
The CR9071E provides 16 digital I/O and 12 pulse counting channels.
Four pulse channels count switch closures; the other eight channels
count low-level ac signals. All of the pulse channels can measure high-
level frequencies up to 1 MHz. The digital I/O channels are used for
digital control, communications, out-put triggering, and pulse count-
ing. The CR9071E supports interval timing and pulse width duration.

MADE IN USA
Easy Connector module allows sensor wiring to remain connected
while the input module’s measurement electronics and the rest of the
datalogger system are used elsewhere.
