Overview
- 2-channel high-speed counter module
- With comprehensive parameterization options for an optimum adaptation to the task and reduction of control load
- Speed and time period measuring
- Storage and comparison functions
- Connection of 24 V encoders
Application
In particular, counter modules detect quick signals with high frequencies and return the counter reading and the current speed to the PLC. The counter control ensures a precise counter result and rapid response in the system via digital input and output signals. Comprehensive parameterization options provide optimum adaptation to the task at hand and reduce control load.
