NA400 - High-Speed Counting Module
- Product Description
- Performance Parameters
-
The NA400HCM401 is an intelligent counting module designed for a wide range of counting and measurement tasks. It captures pulses from 5V or 24V incremental encoders, direction sensors, and starters via directly connectable gate signals. This module alleviates the CPU’s workload by performing the following functions:
1. Directly connect the 5V incremental encoder and the 24V incremental encoder.
2. Directly connect the gate signal via the integrated digital input terminal.
3. Compare functions and output responses via integrated digital outputs. -
