PMC464:
Digital I/O Module, Counter/Timer
• 64 TTL bi-directional I/O
• Four 16-bit counter/timer channels with six operating modes
• Change of state and level interrupts
The PMC464 module provides 64 digital input/ output channels and four 16-bit multifunction counter/timers.
Sixteen digital I/O channels can be programmed as an input or an output on an individual channel basis. The other 48 digital input/output channels are programmed as inputs or outputs on an 8-bit port basis. All inputs support change of state and high/low 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. A conduction-cooled version is also available.
