Bachmann CNT204/H High-Speed Counter Module – Product Description

Description

The Bachmann CNT204/H is a high-speed counter module engineered for precise pulse acquisition across demanding automation environments. It captures fast digital pulses from single-line generators, encoders, and various motion feedback devices with exceptional stability. Moreover, its synchronized input capability ensures accurate phase and frequency measurement in systems with tightly controlled timing. This module supports high-resolution diagnostics, therefore helping engineers monitor complex mechanical movements with confidence.

Overview

Designed for the Bachmann M1 automation platform, the CNT204/H provides four independent counter channels with robust signal filtering and galvanic isolation. In addition, two channels support incremental encoders that receive power directly from the module. The device measures pulse periods with a 42 ns resolution, offering precise timing for advanced control applications. Its LED status indicators make on-site verification simple, which improves system maintainability and reduces unnecessary troubleshooting.
