Common Applications
Product Precautions
Bachmann CNT204 is a four-channel counter module for the M1 automation system. It accepts four single-line pulse-generator inputs, while two channels can be configured for incremental encoders with synchronized measurement functions.
- Four independent counter inputs
- Two incremental-encoder channels
- 42 ns period-measurement resolution
- Input synchronization and supply monitoring
Confirm the exact CNT204 variant, terminal assignment, sensor supply and counter or encoder mode for every channel. Remove module and field power, preserve shielding and run controlled count, period and direction tests before release.
Important Notice: Verify CNT204 from the physical marking and current manufacturer documentation before installation or configuration.

The first document presents model-specific technical and system data. The second provides a distinct installation, connection, commissioning and acceptance workflow.
Pulse counting
Counts four documented single-line pulse-generator inputs in an M1 station.
Incremental encoders
Uses two channels as an approved incremental-encoder interface.
Period and speed measurement
Applies the documented 42 ns measurement resolution to timing applications.
Phase comparison
Measures differential phase on the documented C1/C3 or C2/C4 channel pairs.
Read the applicable Bachmann instructions before work. Verify CNT204 and the installed system configuration.
1
Verify CNT204 and the complete hardware variant before work.
2
Record every channel's counter, initiator or encoder assignment.
3
Confirm sensor supply and terminal-block wiring.
4
Remove module and field power before insertion or wiring changes.
5
Maintain shield termination and separation from noisy conductors.
6
Do not exceed the documented input and encoder limits.
7
Check supply-monitoring and channel LEDs after startup.
8
Prove count, direction, period and synchronization functions before release.
Technical notes
Confirm the exact CNT204 variant, terminal assignment, sensor supply and counter or encoder mode for every channel. Remove module and field power, preserve shielding and run controlled count, period and direction tests before release.
