OV-1

Overview

The CR9000X is a modular, multi-processor system that provides precision measurement capabilities

in a rugged, battery-operated package. The system makes measurements at a rate of up to 100 K

samples/second with 16-bit resolution. The CR9000X Base System includes CPU, power supply, and

A/D modules. Up to nine I/O modules are inserted to configure a system for specific applications.

The on-board, BASIC-like programming language includes data processing and analysis routines.

Software provides program generation and editing, data retrieval, and realtime

monitoring. LoggerNet software can be used for multiple station applications requiring modem

communications and/or where schedule data collection to a PC is required.

CR9032 CPU Module

The CR9032 CPU Module provides system control, processing, and

communication to a PC via the built-in 10BaseT/100BaseT Ethernet port or the

RS-232 port. The CR9032 also has built-in Serial Device for Measurement

(SDM) terminals and a CSI 9-pin port for communication with Campbell

Scientific peripherals. The SDM 12 volt supply is current limited to 1.85

amps. The main processor is a 180 MHz Hitachi SH-4 microprocessor. The

module has 128 MB SDRAM and 2 MB Flash EEPROM.

CR9011 Power Supply Module and AC Adapter

The CR9011 Power Supply Module provides regulated power to the CR9000X

from the internal battery modules. It also regulates battery charging from

power supplied by the AC adapter, a DC input, or other external sources. The

AC adapter may be used where AC power is available (100 - 240 volts) to

provide power to the CR9000X and charge its batteries.

The CR9011 has a relay that allows shutting off power under program control.

The Power Up inputs allow an external signal to awaken the CR9000X from a

powered down state (PowerOff, Section 9). When the CR9000X is in this

power off state the On/Off switch is in the on position but the internal relay is

open. The power LED is not lit. If the "<0.5 " input is switched to ground or

if the ">2" input has a voltage greater than 2 volts applied, the CR9000X will

awake, load the program in memory and run. If the "< 0.5" input continues to

be held at ground while the CR9000X is powered on and goes through its 2-5

second initialization sequence, the CR9000X will not run the program in

memory. The CR9011's 12VOUT supply is current limited to 300 mA.

CR9050 Analog Input Module

The CR9050 Analog Input Module has 14 differential or 28 single-ended

inputs for measuring voltages up to ±5 V. Voltages exceeding ±9 V may cause

errors on other channels. An on-board PRT provides the reference temperature

for thermocouple measurements, while a heavy copper grounding bar and

connectors combine with the case design to reduce temperature gradients for

accurate thermocouple measurements. Resolution on the most sensitive range

is 1.6 µV.

CR9051E Fault Protected 5 V Analog Input Module

The number of channels and measurements are the same as for the CR9050

Analog Input Module. Each input channel is fault-protected so as to permit

over-voltages between +50 V and –40 V without corruption of measurements

on other input channels. All the CR9051E input channels become open

switches when the CR9000X is powered off. The CR9051E is recommended

over the CR9050E for applications where fault voltages beyond ±9 V could

come in contact with the inputs, or when the CR9000X could be powered off

while still connected to sensors that have power applied to them. The

CR9051E supports the same instruction set as the CR9050.

CR9052DC Anti-Alias Filter Module with DC Excitation

The CR9052DC is a high-performance anti-alias filter module that extends the

capability of the CR9000X Measurement and Control System. The module

includes six anti-aliased analog measurement channels with differential input

ranges from ±20 mV to ±5 V. Each input channel has current and voltage

excitation options. Measurement rates up to 50 kHz per channel are possible.

The The CR9052IEPE module allows direct connection of Internal Electronics

Piezo-Electric (IEPE) accelerometers and microphones to CR9000- or

CR9000X-series dataloggers. Each CR9052IEPE includes six channels. Each

channel has a BNC connector, an open circuit indicator LED, and a short

circuit indicator LED which can indicate if the channel is over-or under-driven.

Each channel has a built-in constant current source which is software

programmable to 0, 2, 4, or 6 mA.

CR9058E Isolation Module

The CR9058E is a 10-channel, differential input isolation module. Each

channel has a 24-bit A/D converter which supplies input isolation for up to ±60

V continuous common mode voltage conditions. The full-scale ranges

available are ±60 V, ±20 V, and ±2 V with a resolution to 2 µVolts. Due to its

superb signal to noise ratio, and good resolution, an accurate thermocouple

measurement can be made on the 2 Volt range code. An on-board

programmable DSP provides digital filtering.

CR9055 50-Volt Analog Input Module

The CR9055 50-Volt Analog Input Module has 14 differential or 28 single-

ended inputs for measuring voltages up to ±50 V. Resolution on the most

sensitive range is 16 µV. The CR9055 has a common mode range of ±50 V.

Normally thermocouple measurements would be made on the CR9050 Analog

Input Module (±5 Volt) because of its greater resolution, however they can be

made on the CR9055 if the ±50 V common mode range is necessary.
