PCI Boards PCI Boards NEW! APC464 Digital I/O (TTL) and Counter/Timers The APC464 provides 64 TTL digital input/output channels and four 16-bit multi-function counter/timers. All 64 I/O channels, when set as inputs, support config- uration for interrupts on either a change-of-state or on This module saves money and PCI slots by combining TTL I/O and counter/timer functions on one card. a high-to-low or low-to-high transition. A debounce timer is selectable to help filter out false transitions.
