Page 8: Before Using The Product
The CNT24-4(PCI)H is a PCI bus-compliant interface board that counts input pulse signals from external devices. The CNT24-4(PCI)H has four channels of 24-bit up/down counters, allowing external devices such as a rotary encoder and a linear scale to be connected. Given below are examples of using the board for “detecting a position of the table of a machine tool”... -

A delay of more than four set-cycle clocks may occur depending on noise. If a level changes at a frequency faster than the set-sampling-clock cycle, that level change is invalidated and not correctly counted. Be sure to input signals which are less than the input frequency. CNT24-4(PCI)H... -
