Product Overview

The CNT204/H (00012290-20) is a specialized high-speed counter and positioning interface for the Bachmann M1 automation system. Engineered for precision tasks such as frequency measurement, phase-shift detection, and incremental encoder tracking, this module provides a hardware-based solution for pulse trains that exceed the capabilities of standard digital inputs. The CNT204/H (00012290-20) features four independent channels, two of which are specifically optimized for incremental encoders with A/B tracks, ensuring synchronized data acquisition at the hardware level.
