FUNCTIONAL DESCRIPTION

The USB-IIRO4-2SM is a USB multifunction device, incorporating a USB 4-port hub internally to provide four optically isolated digital inputs,

four electromechanical relay outputs and two ports of RS-232/422/485 serial communication in one small product. The digital portion is ideal

for adding easy-to-install isolated input and relay output capabilities to any PC or embedded system with a USB port. This single USB multi-

function device is ideal for a variety of applications such as industrial monitoring, control and communication.

DIGITAL

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

40Hz 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 relay outputs are de-energized at power-up to prevent an unintended control output signal. Data to the

relays is latched. The relay contacts and isolated inputs are available via a mounted DB25 connector or, for OEMs, a 26-pin IDC type vertical

keyed shrouded header. For testing purposes and low current applications 5VDC and ground pins are provided on the same connector. The

digital portion of the USB-IIRO4-2SM is excellent in applications where only a few on-board relays are required and a small number of inputs

must be isolated such as in test equipment, instrumentation and process control.

SERIAL

The serial section is a two-port asynchronous serial communication adapter designed for use with any computer system equipped with a USB

port. Multiple peripherals such as POS, barcode scanners, scales, date-entry terminals, data acquisition modules, and automation equipment

can now be recognized and used on a single USB port. Simply install the included software and connect the unit to your USB port. It instantly

provides two RS-232, RS-422, or RS-485 serial ports which can be selected on a port by port basis. It is now easier than ever to add serial

ports and serial devices to any application along with easy plug-and-play and hot-swapping features.
