Product short description:
  • 40 I/O channels: 24 differential and 16 TTL
  • Four 16-bit or two 32-bit counter/timers

Consult factory for long-term availability.

APC424: PCI Digital I/O (differential & TTL) and Counter/Timers Description

The APC424 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.

Four 16-bit multifunction counters/timers can be configured 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.

The APC424 module saves money and PCI slots by combining differential I/O, TTL I/O, and counter/timer functions on one card.
