PCM-CTC

Description

The industrial PCM-CTC card is designed to solve the common timing problems in industrial systems design. Six independent 16-bit channels are capable of frequency/event counting from DC to 8 MHz, pulse marker or squarewave generation, time interval measurements, and oneshot simulation. All six channels have a buffered Clock, Gate, and Output available. Jumper headers provide source selection and cascading to yield maximum configuration flexibility.

Features

  • Six independent 16-bit Counter/Timers
  • Uses two 82C54 Programmable Interval Timers
  • Six programmable counter modes per channel
  • Handles inputs from DC to 8 MHz
  • Binary or BCD counting
  • Clock, Gate, and Out signals from 6 channels buffered and accessed via two connectors
  • Direct interface to WINSYSTEMS’ TRM-500-3 flow meter termination card
  • On-board 82C59A Interrupt Controller generates eight vectored interrupts
  • Two additional external interrupt input sources
