CR9041 A/D and Ampli er Module

 e CR9041 provides signal conditioning and 16-bit,

100 kHz A/D conversions.

CR9000XC

 e CR9000XC is a compact version of the CR9000X.

 e CR9011 Power Supply Module, CR9032 CPU

Module, CR9041 A/D and Ampli er Module,  ve I/O

module slots, one 7 Ah sealed rechargeable battery,

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.  e CR9000X series

is CE compliant under the European Union’s EMC Di-

rective, meeting ESD, EMC, Fast Transient standards.

I/O Modules

A mix of I/O modules is selected based on the mea-

surements required for the application. Individual

I/O modules can be “swapped out”, allowing the

system to be recon gured 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.

CR9050 and CR9051E Analog Input Modules

The CR9050 and CR9051E provide 14 differential

(28 single-ended) input channels for measuring voltages

up to ±5 V. Resolution is 1.6 µV on the most sensitive

range. Both modules have an on-board reference PRT and

connectors for precise thermocouple measurements.  e

CR9051E channels are fault protected to +50 V/-40 V.

 is prevents overvoltage on one channel from cor-

rupting measurements on other channels.  e 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

 e CR9052DC is a high-performance anti-alias  lter

and Fast Fourier Transform (FFT) spectrum analyzer

with dc excitation.  e CR9052IEPE module provides

excitation and signal conditioning for IEPE-type

(Integral Electronic Piezo Electric) accelerometers,

microphones, and pressure transducers. Detailed

information and speci cations are available in the

CR9052DC and CR9052IEPE brochure.

CR9055 or CR9055E 50-Volt Analog Input Module

 e CR9055(E) has 14 di erential (28 single-ended)

programmable input channels for measuring voltages

up to ±50 V. Resolution to 16 µV is available.

CR9058E Isolation Module

 e CR9058E provides 10 isolated di erential 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 maximized for the speci ed integra-

tion time. For precise thermocouple measurements, the

CR9058E includes an on-board reference PRT.

CR9060 Excitation Module

 e CR9060 provides six continuous analog outputs

(CAOs), 10 switched excitation channels, and eight

digital control outputs.  e CAOs have individual

digital-to-analog converters for proportional control,

waveform generation, and excitation. Each CAO sources

up to 50 mA between ±5 V.  e excitation channels

provide precision voltages for bridge measurements.

 e digital outputs control external devices.

CR9071E Timer/Pulse Input Module

 e 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.  e digital I/O channels

are used for digital control, communications, out-

put triggering, and pulse counting. The CR9071E

supports interval timing and pulse width duration.

9050E 5V ANALOG INPUT

9050EC

5V ANALOG INPUT CONNECTOR

MADE IN USA

Easy Connector module allows sensor wiring to remain con-

nected while the input module’s measurement electronics

and the rest of the datalogger system are used elsewhere.
