FUNCTIONAL DESCRIPTION
The USB-IDIO-16 is an ideal solution for adding portable, easy-to-install isolated input and solid state output capabilities to any computer with a USB port. The
USB-IDIO-16 is a USB 2.0 high-speed 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 features hotplug functionality allowing for quick connect/disconnect whenever you need additional I/O on your USB port.
Featuring 16 high side power MOSFET switch outputs and 16 optically isolated digital inputs, the unit is the smallest of its kind for digital monitoring and control
using USB. The isolated, non-polarized inputs may be driven by either DC sources of 3-31V (or higher by special order) or AC sources at frequencies of 40Hz
to 10kHz. Individual channel-to-channel isolation allows every channel to be physically and electrically separated from the others. 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 ac-
cessed via a 34-pin IDC type vertical header. The fully protected isolated outputs are de-energized at power-up to prevent an unintended control output signal.
Data to the solid state outputs are latched and are available via a 50-pin IDC type vertical header. The unit contains an internal, removable screw termination
board with onboard removable screw terminals to simplify wiring connections.
These boards are especially useful in applications where high common-mode external voltages are present. Isolation is required to guard electronics from
transient voltage spikes and offers greater common-mode noise rejection in electronically noisy surroundings containing industrial machinery and inductive
loads. These applications include factory automation, energy management, industrial ON/OFF control, security systems, manufacturing test, and process
monitoring. In addition to protecting industrial applications from accidental contact with high external voltages, the isolation provided eliminates troublesome
ground loops.
The USB-IDIO-16 was designed to be used in rugged industrial environments but is small enough to fit nicely onto any desk or testing station. The board is
PC/104 sized (3.550 by 3.775 inches) and ships with or without a steel powder-coated enclosure with an anti-skid bottom. A DIN rail mounting provision is
available for installation in industrial environments.
