Data acquisition through the USB port
Marlboro, Mass. -The DT9800 Series family of USB data acquisition function modules offer 16SE/8DI inputs with 12- or 16-bit resolution, up to 100kS/s throughput, 16 digital I/O lines, and 2 user counter/timers. Users also have optional 12- or 16-bit analog outputs. Users are said to obtain all the benefits previously available only with plug-in boards, in the convenience of a plug-and-play USB module. Modules are small and portable, enabling users to transport them to and from different PCs. They're also hot swappable, allowing users to plug and unplug while the computer is on. No rebooting is required. The on-board processor takes the workload off the host PC processor by controlling and supervising all subsystems on board. No additional power is needed, and its 500 V isolation is said to provide safe, low-noise measurements. This isolation also guards against ground loops, protecting the user's PC and data.

Multichannel counter/timer card series

San Diego, Calif. -PCIDCCx-P Series PCI bus counter/timer cards are typically used for PC-based data acquisition applications such as monitoring encoder pulse outputs for motion control, or as a frequency/pulse counter. The series offers 5-, 10-, and 20-channel cards. The heart of each board is an AMD AM9513 counter/timer chip, which provides five independent 16-bit up/down counters. The counters can be programmed to count either up or down in binary or BCD. A selection of various internal and external frequency sources and outputs may be chosen as inputs for individual counters, with software selectable active-high or active-low polarities. Other features include frequency measurement to 7MHz, internally cascadable counters, and 0-50 ° C operating temperature range.

Family of PCI bus DAC boards
San Diego, Calif. -Acces I/O Products' new family of cards for PCI bus computers offer 40 models from which to choose. Each model supports most popular data acquisition applications. The series includes several models each of digital-to-analog, digital I/O, serial communications, and utility cards-all designed to operate in harsh environments. Acces I/O keeps costs down by porting what were the most popular ISA data acquisition applications to the PCI bus without extra enhancements. All cards are able to withstand temperatures of 0-60 °C and 0-90% relative humidity (noncondensing). PCI Series cards can be installed in any 5 V PCI bus long slot.

Temperature indicator/logger
San Diego, Calif. -The Doric 5000 is a programmable, PC-compatible digital temperature indicator/data logger. The unit also features RS-232 serial communications and Microsoft Windows-based software. Configuration is performed via the front panel, including calibration of sensor input type, sampling rate, limit settings, and resolution. Other key features include a four digit alphanumeric display; the ability to take readings from six thermocouple types or two RTD types; and scalable analog ouput, dual alarm, and multiple input options. All front-panel setup commands can be executed remotely from a PC through the Doric 5000's software, which allows for simultaneous viewing of all channel data, limit/alarm status, and minimum/maximum values.

High-speed sampling
Bellevue, Wa. -DAP 440a/446 has four on-board A/D converters that each can acquire 800k 14-bit resolution samples per second simultaneously, for an aggregate throughput of 3.2M samples per second. The board has 16 Mb of on-board memory for data buffers and uses DMA bus-mastering to transfer data to the PC. Sixteen on-board single-ended inputs, multiplexed in groups of four, share the 3.2 million samples per second throughput of the DAP 4400a. If an application requires sixteen simultaneous inputs, each acquiring data at 800k samples per second, then four synchronized DAP 4400a boards, installed in one PC, can deliver the aggregate throughput of 12.8 million samples per second shared by these 16 simultaneous inputs.
