Product Description:

The Danaher CM030171211 Counter processes input signals up to 40,000 pulses per second and supports batch counting for efficient tracking of grouped operations. This timer and controller series module precision and flexibility make it ideal for environments that require fast, accurate measurement and control across multiple production cycles.

The CM030171211 counter is able to register pulses moving in a single direction, in both directions and from encoders that emit two out of phase signals and it communicates over an RS-485 interface which is a robust, differential signal system ideal for transmitting data over long distances and in electrically noisy environments. This module's actual weight excluding any packaging, is approximately 0.585 pounds and it uses a single line red Light Emitting Diode screen to show values or status which is energy efficient and visible in various lighting conditions. Its output behavior includes a delay after receiving an input signal or follows a basic start up response and it is able to retain stored data even when powered down because of its memory that does not require continuous electricity to maintain its contents. The controller is built to be installed in a standardized DIN panel opening, specifically the 1/8 size and it includes a feature to restrict access to its settings or functions.

This CM030171211 counter can accept input signals either from positive supply sourcing sensors (PNP) or from simple mechanical switches that complete a circuit, and its frontal dimensions are 48 mm by 96 mm that conforms to the 1/8 DIN standard size. Its display includes internal illumination which enhances visibility in low light or dim environments and it uses digital circuitry as a method of counting towards a target value.

Frequently Asked Questions about CM030171211:

Q: How does the RS-485 communication benefit the CM030171211 counter in industrial setups?

A: The RS-485 ensures stable, long-distance communication even in noisy factory environments. It also allows multi-device networking for synchronized control operations.

Q: Why is nonvolatile RAM important in the CM030171211 counter?

A: The Nonvolatile RAM retains all counting and configuration data during power outages. This ensures operations resume without manual resets after downtime.

Q: How does batch counting improve productivity with this unit?

A: Batch counting helps group and track repeated production cycles automatically. This reduces manual counting errors and boosts throughput efficiency.

Q: Why is the sourcing (PNP)/contact closure input versatility important in the controller?

A: It allows compatibility with a wider range of industrial sensors and switches. This reduces integration challenges in multi-source input systems.

Q: How does the locking feature enhance the reliability of the CM030171211 counter?

A: It prevents unauthorized access or accidental configuration changes. This protects system integrity in shared or high-traffic industrial areas.
