Compact USB 32-Channel Optically Isolated Input/Relay Output Module Ideal for High-Speed Digital Control

SAN DIEGO, CA (PRWEB) January 18, 2006

ACCES I/O Products, Inc. is pleased to introduce its latest embedded digital I/O board packaged in a small, rugged, industrial enclosure – Model USB-IIRO-16. Featuring 16 Form C (SPDT) electromechanical relays and 16 optically isolated digital inputs, the unit is a very dense, portable, embedded solution for digital monitoring and control in any PC or embedded system with a USB port. The unit contains an internal, removable screw termination board with onboard removable screw terminals to simplify wiring connections. The USB-IIRO-16, like the PC/104 and PCI versions from ACCES I/O, 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 OEM version provides just the board without the enclosure and internal screw termination board and is ideal for a variety of embedded OEM applications.

What makes the OEM option unique is that its PCB size and mounting holes match the PC/104 form factor (without the bus connections). This allows our rugged digital board to be added to any PCI-104 or PC/104 stack by connecting it to a simple USB port usually included on-board with embedded CPU form factors such as EBX, EPIC, and PC/104 especially important since many newer CPU chipsets do not support ISA and have plenty of USB ports. Future stacks will be using the extremely fast PCI Express bus which is essentially overkill for simple digital monitoring and control. The USB-IIRO-16 OEM board can also be added into many pre-existing standard PC/104 based systems and enclosures while the standard unit with its tiny enclosure and cable-less screw termination board provides portable connections to laptops for the mobile test market.

Key features of the USB-IIRO-16 include:
