The isolated, non-polarized inputs may be driven by either DC sources of 3-31 V (or higher by special order) or AC sources at frequencies of 40 Hz to 10KHZ. Optically isolating the digital inputs from each other, and from the computer, assures smooth, error-free data transmission in noisy, real-world environments. The input channels are available via a 34-pin IDC type vertical header. The relay outputs are de-energized at power-up to prevent an unintended control output signal. Data to the relays is latched. The relay contacts are available via a 50-pin IDC type vertical header.
The rugged industrial unit contains an internal, removable screw termination board (USB-STB-84) with onboard removable screw terminals to simplify wiring connections. The USB-STB-84 mounts directly into the vertical IDC connectors of the USB-IIRO-16 PCB. The USB-IIRO-16, like the PC/104 and PCI versions, is excellent in applications where on-board relays are required and inputs must be isolated such as in test equipment, instrumentation, and process control. The USB-IIRO-16 is a 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 OEM version provides just the board without the enclosure and internal screw termination board and is ideal for a variety of embedded OEM applications.
Features
The USB-IIRO-16 is plug-and-play which
allows quick connect or disconnect whenever you need additional I/O on
your USB port. The module utilizes a high-speed custom function driver
optimized for a maximum data throughput that is 50-100 times faster
than the USB human interface device (HID) driver used by many competing
products. This approach maximizes the full functionality of the
hardware along with capitalizing the advantage of high-speed USB 2.0.
The USB-IIRO-16 is supported for use in most USB supported operating
systems and includes a free Linux and Windows 98se/Me/2000/XP/2003
compatible software package. This package contains sample programs and
source code in Visual Basic, Delphi, C++ Builder, and Visual C++ for
Windows. Also incorporated is a graphical setup program in Windows.
Third party support includes a Windows standard DLL interface usable
from the most popular application programs. Embedded OS support include
Windows Xpe.
