Economical Paperless Recorder
DataChart 1250 paperless recorder features two user-configurable inputs for measuring DC voltage, current, thermocouples, RTDs and frequency/RPM. Four internal alarm set points can be programmed to activate the two SPDT relay outputs. Data is displayed in real-time graphic or digital format on an LCD display, and is stored on CompactFlash cards up to 2 G at up to100 samples/sec for both channels. Power is supplied via A/C wall transformer or via optional internal rechargeable NiMH battery pack. Monarch Instrument; 603/883-3390;

Power from the Port
USB data acquisition modules feature 8-channel multifunction I/O, digital I/O and temperature measurement capabilities. Model 18200-00 features a 1.2 kS/sec sampling rate. Model 18200-10 provides a sample rate of 50 kS/sec. Model 18200-20 provides 16-bit analog inputs with a throughput of 100 kS/sec. Model 18200-30 provides inputs for eight different thermocouple types (J, K, T, R, S, B, N, E), 2-, 3- or 4-wire RTDs, thermistors and semiconductor temperature sensors. Model 18200-40 features eight bits of digital I/O, 500 V of isolation and built-in ambient temperature sensing. Cole-Parmer; 800/323-4340;

Worldwide Communication
APM4AM-ORB data acquisition device uses a low-earth-orbit satellite network for communication and monitoring of equipment. Notifications of alarm events are available via email, fax, page and/or voice. Data can be viewed securely via standard browser on the Internet from anywhere in the world. It has a total of six inputs. Channels 1-4 can be configured to monitor analog or digital signals, Channels 5 and 6 can be configured as digital or accumulator inputs. American Innovations; 800/229-3404;

Open Channels of Communication
DD-400 data monitor features cellular, spread spectrum and Wi-Fi wireless communication options, as well as a 4 MB non-volatile flash memory. RS-232 communications come as standard on all units, with Ethernet and RS-485 wired communication options available. It operates in temperatures ranging from -40 °C to 75 °C. All inputs include lightning and static protection. Scientific Technologies Inc.; 888/52507300;

Embedded Counter/Timer Board
USB-CTR-15 embedded digital board features 15 independent 16-bit counter/timers. The unit is a true USB 2.0 device, offering the highest speed available with the USB bus. It is fully compatible with both USB 1.1 and USB 2.0 ports. The unit is plug-and-play, allowing connect/disconnect whenever you need additional counter/timer devices on your USB port. I/O wiring connections are provided via an industry-standard, 50-pin IDC connector or via a removable screw terminal adapter board. Acces I/O Products; 800/326-1649;

Servo/Stepping Motion Cards
DASP-52504 and DASP-52506 PCI-bus, high-speed four- and six-axis motion control cards control both servo and stepper motors. Cards support both pulse and voltage output, and RTX drivers in the field. Both support a four-dimension API software structure (X,Y,Z,C axis) that allows users to develop application programs to control four-axis motors and various software and programs, such as VB, VC, BCB, Delphi and Labview 6.0/7.0. Axiomtek; 626/581-3232;

Check the Pressure and Temperature
iPTX virtual chart recorder monitors and records pressure and temperature of air (or inert gas) over an Ethernet network or the Internet. The included transducer measures pressure from 0-200 psi and temperature from 0-70 °C (32-158°F). It automatically sends alarms to an individual or group by email or text messaging cell phones. Active Web pages display real time readings, charts of air pressure and temperature or log data in standard data formats. Newport Electronics; 800-NEWPORT;

Leader of the PAC
SNAP-PAC-R2 programmable automation controller supports additional I/O configurations for cell control, data acquisition and remote monitoring applications. It supports up to 512 points of analog, digital and serial I/O modules. Features include PID loop control, floating point math and dual Ethernet communications with serial PPP. Two independent, auto-negotiating 10/100 Mbps Ethernet interfaces can be used for network segmenting or Ethernet link redundancy. Opto 22; 800/321-OPTO;

Plotting and Analysis Software
Analyse-Plus software allows you to plot and analyze data to make quick conclusions with regard to variability and process control. It collects data by importing text via DDE or by A/D conversion, and allows plotting individual or overlaid plots with multiple y-axis labels including statistics, zooming, Fourier analysis (frequency and period scales), auto- and cross-correlation. Optional streamlined import tools are available for several DCSs, that also import names, tags and sample period. Givens Control Engineering; 905/631-8293;

Follow the Trend
Minitrend QX and Multitrend SX paperless recorders have touch-screens, increased input capability, input isolation and scan rates to 20 ms. They also have advanced mathematical calculations, events, totalization, custom screens, health-watch/maintenance, OPC interface and a standard NEMA 3/IP55 front-face protection rating. Honeywell; 973/455-2000;

Real-Time Recording and Playback
StreamStor Amazon SATA disk controller is a full-length, 64-bit Universal, PCI bus board that controls 16 Serial ATA drives on eight buses. It records in both single and multi-channel on the PCI bus. A modular mezzanine interchangeable interface system can be modified with any number of daughter cards such as FPDP I and II, Channel Link and Star Fabric. The unit features 1 G of onboard memory buffer for uninterrupted data acquisition and playback, data forking, simultaneous playback while record, data partitioning and wrap/circular recording. Conduant; 303/485-2721;  

Digitizer Cards
AP240 and AP235 dual-channel reconfigurable PCI analyzers feature advanced peak analysis and front-end analog-to-digital conversion with up to 1 GHz bandwidth (500 MHz for the AP235). The onboard, FPGA-based data processing unit isolates peaks from waveform data obtained at up to 2 GS/s (1 GS/s for the AP235), and transfer this peak data in the form of time and/or amplitude to the host PC. Peaks are located using an advanced hysteresis algorithm that measures the true peak position and amplitude, and allows multiple peaks to be defined within a wide range. Acqiris; 877/227-4747;
