5.6.2 PCD3.H110, Universal counting and measuring module
Application
Measuring and fast counting module for general counting and simple motion control
tasks; also for specific applications such as frequency measurement, period and
pulse length measurement, etc. The module is equipped with an FPGA (Field
Programmable Gate Array) and can be programmed for special high volume
applications by using a plug-in PROM.
