Acromag, Inc. AcPC Series Digital I/O and Counter/Timer AcPC464

•64 digital input/output channels 16-bit counter/timer channels with six operating modes Change of state and level interrupts The AcPC464 module provides 64 digital input/ output channels and four 16-bit multifunction counter/timers. All 64 I/O channels, when set as inputs, support configuration for interrupts on either a change-of-state or on a high-to-low or low-to-high transition. A debounce timer is selectable to help filter out false transitions. Four 16-bit multifunction counters/timers are configurable for pulse width modulated output, watchdog timer, event counter, frequency measurement, pulse width measurement, period measurement, or one shot pulse output. The four 16-bit counters can also be configured into two 32-bit counter/timers.
