PC/104 Relay Module Hosts 36 Channels

he Model 104-II32-4RO, a 36-channel PC/104 relay-output board, features 32 optically isolated digital inputs with change-of-state interrupt generation and four electromechanical relay outputs. It provides connections to an assortment of devices including sensors, switches, controllers, powered circuits, and others. Inputs can be driven by either dc sources from 3V to 31V (or higher by special order) or ac sources at frequencies from 40 Hz to 10 kHz. Each input circuit includes a jumper selectable filter that may be manually disabled to improve the board's typical response time to 10 μs when used with faster dc inputs. Other features include a 5V general-purpose output, selectable change-of-state detection, interrupt sharing, and Schmitt trigger buffers. The board comes with a software package that is compatible with DOS, Windows 95/98/Me/NT/2000/XP/2003, and Linux. Single-unit price is $295. ACCES I/O PRODUCTS INC., San Diego, CA. (800) 326-1649.
