Counter Module Bachmann CNT204/R

Product Description

The CNT204/R (Part Number: 00012290-20) is a high-precision, high-speed counter and position measurement module designed for the Bachmann M1 automation platform. It provides four independent, galvanically isolated counter channels, optimized for interfacing with incremental encoders and high-speed sensors in motion control and positioning applications.

The module features integrated differential inputs (RS422) and supports both 5 V and 24 V signal levels, ensuring compatibility with a broad range of industrial rotary and linear encoders. In addition to standard pulse counting, the CNT204/R supports frequency measurement, period duration analysis, and gated counting. Its robust electrical design ensures reliable signal acquisition in high-EMI environments, such as wind turbine nacelles, heavy machinery, and industrial production lines.

Technical Specifications

Industrial Applications

The CNT204/R is a standard solution for wind turbine pitch control systems, where precise blade angle feedback and fast dynamic response are critical. It is also widely applied in packaging machinery for high-speed axis synchronization and in hydraulic and servo-driven systems for accurate piston or carriage positioning using incremental linear encoders.

Technical FAQ

Does the CNT204/R support SSI absolute encoders?
No. The CNT204/R is exclusively designed for incremental encoder signal processing. For absolute encoder applications using SSI, the Bachmann SSI202 module should be selected.
