Digital I/O USB Data Acquisition (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.
In many cases, we only need to know a simple status about the device we are trying to collect data from, whether something is true or false, on or off, in one position or another. In these cases, we can determine what we need to know using a digital input, or control these things by a digital output. Digital I/O can fit into many applications. Anywhere your application requires something switched from one state to another, or a dry contact monitor. These products are 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.
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. These modules are especially useful where high-speed data needs to be captured or output for testing or stimulus/response applications. These include testing and debugging, laboratory automation, manufacturing test, image capture, process monitoring, datasource emulation, and many more which require the need for high-speed parallel data transfer.
