USB Data Acquisition (DAQ) Products

USB Data Acquisition (DAQ) Products

ACCES now offers USB-based data acquisition and control in both standard packaging and embedded OEM USB/104 board only options. These USB DAQ devices are perfect for a variety of applications requiring monitoring, control and industrial serial communications. USB is by far the most popular and compatible standard data interface for direct PC connection. Add the features you need in your application in hours, not days. Choose from over 100 different models and options (including extended temperature) encompassing analog I/O, digital I/O, counter/timer, and serial I/O configurations. Experience simple and immediate connection to any PC or embedded system with a USB port.

Our USB OEM product line features two different size form factors – USB/104 and USB/PICO. The USB/104 product line PCB size measures just 90mm x 96mm and the mounting holes match the PC/104 form factor for quick and easy installation in both new and existing PC/104-based systems. Our USB/PICO line was created for our customers which demand an even smaller footprint and certain specific I/O configurations. The size of these modules is exactly half that of PC/104 (72mm x 60mm) and can be mounted virtually anywhere, including Pico-ITXe next generation embedded CPUs. Both USB/104 and USB/PICO are stackable or unstackable, making them one of the most versatile I/O form factors currently available.

For existing PC/104 users, what makes our embedded OEM board-only option unique is that its PCB size and mounting holes match the PC/104 form factor. Our USB/104 versions are excellent for installation into OEM equipment or adding I/O to an existing PC/104 stack.

All of our USB DAQ products feature Plug-and-Play, hot swappable installation for quick connect or disconnect in mobile, embedded, or stationary systems. All ACCES USB products are compatible with USB 2.0 and most fall into the highest-speed category of this specification. These boards are excellent for easy installation into OEM equipment and eliminate the labor required with traditional plug-in boards. No screws, reboots, I/O addresses, DIP switches, DMA channels or IRQ settings. All products feature a Type B USB connector with industrial strength and a high-retention design. For embedded OEM type applications, an additional micro-fit embedded USB input header is provided.

Call us today and start your application tomorrow. And remember, if you don’t see what you need, ask us and we will make it for you.

Multifunction Analog Input/Output USB DAQ Products

Select from a large assortment of 16, 32, 64, 96, and 128-channel multifunction analog input modules. Analog inputs are available as either single-ended or differential. Choose from either 12 or 16-bit versions with speeds up 500kHz. All models incorporate two 16-bit analog outputs, 16 lines of digital I/O, and are integrated inside a rugged, small sized steel enclosure with an anti-skid bottom. A DIN rail mounting provision is available for installation in industrial environments. Additional features include software autocalibration (real-time) and on-board references for increased accuracy. Extended temperature (-40? to +85?C) is available.

A wide range of flexible signal conditioning types per channel are also offered. These include options such as RC filters on each input, voltage dividers on each input, 4-20mA current inputs, thermocouples (temp sensor for cold junction), RTD measurement, as well as bridge completion.

For applications requiring analog inputs only, a line of cost efficient USB products offers all of the features described above except no analog outputs are included.

Analog Output USB DAQ Products

Select from an assortment of 12 and 16-bit USB analog output modules. The multifunction USB-AO series offers 4, 8, or 16 analog outputs, 2 analog inputs, along with 16 lines of digital I/O. For those of you that require waveform outputs, our USB-DA12-8A features eight individual 12-bit D/A converters with full Arbitrary Waveform Generator functionality (AWG/ARB) and up to 125 KSample/second simultaneously on eight channels.

Digital Input / Output USB DAQ Products

ACCES I/O Products provides a complete family of industrial strength digital I/O products for compact control and monitoring applications. Choose from 4 to 96 channels offering various voltage, isolation and counter/timer options. Using one of our 4-port USB hubs, up to 384 channels of high-density digital I/O can be realized.

Our fastest USB digital I/O unit to date (Model USB-DIO-16H), features 16 high-speed buffered digital inputs or digital outputs at continuous, sustained streaming speeds up to 16 MB/s for fast, unlimited waveform length. The module is also capable of 80 MB/s bursts with handshaking signals for synchronizing communications.

Ideal for applications sensing TTL, LVTTL, CMOS logic or monitoring dry contacts and to control external relays, drive indicators and audible alarms as well as controlling external devices such as LEDs and system controllers? ACCES I/O’s USB digital products will meet the needs of your embedded kiosk, test, control, monitoring and alarm applications.

Serial Communication USB Products

ACCES I/O Products USB to Serial devices are designed for use with any computer system equipped with a USB port. Simply install the included software and connect the unit to your USB port and transform it into asynchronous serial ports for communication with serial instruments. 1, 2, and 4-port models are available offering users the choice of selectable RS-232, RS-422, or RS-485 protocols per port. All units include a rugged steel enclosure with attractive powder coat finish and anti-skid bottom and options for DIN-rail mounting and extended temperature.

Multiple peripherals such as POS, barcode scanners, scales, date-entry terminals, data acquisition (DAQ) modules, and automation equipment can now be recognized and used on a single USB port. It is now easier than ever to add serial ports and serial devices to any application with the trouble-free plug-and-play and hot-swapping features USB provides.
