Description
Overview
The IC693APU300 is a high-speed counter module for the Series 90‑30 PLC family. It provides independent, accurate pulse counting for applications involving encoders, flow meters, proximity switches, and other pulse-generating devices. By operating independently of the CPU scan, it ensures precise real-time counting for motion control, material handling, and process monitoring.
