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.

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.

Overview

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.
