October 1, 2008 - The 7I64 is an 24 output, 24 input isolated I/O card. The 7I64 provides 24 Isolated 48VDC 2.5A output drivers. All output drivers are low saturation voltage MOSFETS for low power dissipation. Each of the 24 output switches is isolated from the others, allowing high side, low side, push-pull and other output switch configurations.
The 24 OPTO-isolated inputs will operate with input voltages from 5 to 24 V. Reverse protection diodes are provided to allow use with AC inputs. A built in watchdog timer turns all outputs off if the 7I64 is not accessed with in the selectable watchdog timeout interval. The 7I64 has three host interface methods, USB, Serial RS-422 and SPI. The 7I64 can be USB powered.
The serial interface supports baud rates from 115.2K to 2.5M baud. The SPI interface is compatible with MESAs Anything I/O cards and can be used for high speed real time I/O. A SPI breakout card (7I46) allows up to six 7I64s to connect to a single 50 pin Anything I/O connector.
The SPI interface supports data rates to 10 Mbps so a full read/write of all 48 I/O bits takes approximately 3 uSec. 3.5 mm screw terminal compatible plugs are used for isolated I/O. Price of the 7I64 is $132 in 100's
