Acromag, Inc. products

The AcPC424 provides 24 differential input/outputs, 16 TTL input/output channels, and four 16-bit multifunction counter/timers. The 16 TTL input/output channels can be programmed as inputs or as outputs on an individual channel basis. The 24 differential input/output channels are programmed as inputs or outputs on an 4-channel port basis. All input channels can be enabled for change of state, low, or high level transition 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.
