Description
The Bachmann CNT204/H Counter Module integrates four independent counting channels, designed specifically for single-wire pulse generators, with two channels flexibly configurable as incremental encoder inputs. The module supports A-/A+, B-/B+, and N-/N+ differential signal inputs, and provides 1x, 2x, and 4x edge counting and pulse direction modes, enabling precise capture of position and velocity information during high-speed motion.

The module has a maximum input frequency of 1 MHz (RS422) or 300 kHz (HTL), with a built-in adjustable input filter ranging from 185 kHz to 6 MHz (default 6 MHz setting) to ensure stable interference suppression even in complex industrial environments. Its 32-bit counting resolution ensures high accuracy and reliability during long-term operation or high pulse density applications.

The CNT204/H supports period measurement with a resolution of 42 ns, enabling high-precision speed and time analysis. It also supports differential measurement, allowing for phase difference detection between channels C1 and C3 or C2 and C4, providing reliable data support for synchronous control and dynamic monitoring.

The module operates from 18 to 34 VDC, and the encoder power can be directly supplied from the module via a connector, simplifying system wiring. Each counting channel is equipped with a green status indicator LED and comprehensive power supply voltage monitoring. Its wide temperature range (-30 °C to +60 °C) and industrial-grade environmental adaptability make the CNT204/H ideal for mechanical control, energy efficiency systems, and high-dynamic automation applications.
