PMC Modules PMC Modules NEW! PMC464 Digital I/O and Counter/Timers 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 This module saves money and PMC slots by combining digital I/O, and counter/timer functions on a single card. other 48 digital input/output channels are programmed as inputs or outputs on an 8-bit port basis. All inputs Counter output: Each counter has one output signal. The TTL Specifications support change of state and high/low level transition output is used for waveform output, watchdog active indi- Digital I/O cator, or 1.6µS pulse upon counter function completion. interrupts.
