ISOLATED I/O CARD
7I64 I/O card provides 24 isolated 48 Vdc 2.5 A output drivers. The 24 opto-isolated inputs operate with inputs 5–24 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 within the selectable watchdog timeout interval. The 7I64 has three host interface methods, USB, Serial RS-422 and SPI.
