Acromag - Model AcPC424 -Digital Input/Output Module
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.
- 24 differential I/O, 16 TTL I/O
- Four 16-bit counter/timer channels with six operating modes
This module saves money and CompactPCI slots by combining differential I/O, TTL I/O, and counter/timer functions on one card.
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.
- 0 to 70°C (-40 to 85°C E version)
Digital I/O
- 40 digital input/output channels:
– 24 differential input/outputs
– 16 TTL input/output channels
– Programmable change of state/level interrupts
– Input signal filtering debounce logic
Counter/Timer
- Four 16-bit or two 32-bit counter/timer channels (control lines shared with 16 TTL I/O channels)
- Six operating modes:
– Pulse width modulation
– Watchdog timer
– Event counter
– Frequency measurement
– Pulse width or period measurement
– One-shot and repetitive one-shot
– TTL-compatible thresholds
– Power-up and system reset are failsafe
