Industrial PC/104 CTC Counter Timer
Industrial PC/104 CTC Counter Timer
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.
