OVERVIEW

The 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 square-wave generation, time interval measurements, and one-shot simulation. All six channels have a buffered Clock, Gate, and Output available. Jumper headers provide source selection and cascading to yield maximum configuration flexibility.
