CM030171211

The Danaher CM030171211 from Danaher is a high-performance programmable counter positioned within the Timers and Controllers series, delivering precision measurement and control for industrial automation. This module features a robust NEMA-4 rated front panel enclosure and compact 1/8 DIN mounting footprint (48 mm × 96 mm). Powered over a wide range of 85-265 VAC, it supports industrial power standards and offers an Accessory Power Output of 12 VDC, 120 mA max for external sensors. With a total Weight of 2.5 lbs (1.13 kg) and operating temperatures from 32°F to 122°F (0°C to 50°C), the CM030171211 is designed for reliability in harsh environments. It also incorporates nonvolatile memory to preserve configuration and counts during power interruptions.

The CM030171211’s core technical capabilities include a Count Capacity of 6 Decades with Polarity and 7 Solid State Outputs rated at 28 VDC/100 mA sink max for versatile switching functions. It provides 2 Inputs accepting either contact-closure or 3.5 to 15 VDC square wave signals, enabling compatibility with proximity sensors or mechanical switches. Communication is handled via a 4-Wire RS-485 serial interface and RS-422/485, ASCII, programmable baud rate support for integration with PLCs or SCADA systems. The built-in Red LED Display (0.6 in/15.4 mm) with programmable decimal point ensures clear readouts, and the unit’s nonvolatile memory protects data integrity. Additional technical specs include an operating temperature range of 0°C to 50°C and a rugged NEMA-4 rated enclosure for splash-proof operation.

Operational features of the CM030171211 optimize functionality and usability on the factory floor. The counter processes signals up to 40,000 pulses per second in single or bidirectional modes, and it can interpret quadrature inputs from incremental encoders. An internal delay function allows precise timing control after signal reception, and batch counting modes facilitate grouping operations for production yield tracking. The integrated nonvolatile memory ensures that count values and parameters are retained through power cycles. A user-configurable access code restricts parameter changes, helping to secure setup against unauthorized tampering. The bright single-line red LED screen with internal illumination guarantees readability in low-light conditions, enhancing operator efficiency.

Integration into existing automation systems is streamlined by the CM030171211’s standardized 1/8 DIN panel cutout and versatile RS-485 interface. The unit’s 12 VDC accessory output can power PNP sensors directly, simplifying wiring. Its combination of compact size, robust NEMA-4 protection, and flexible I/O makes it ideal for packaging machinery, conveyor systems, labeling equipment, and other OEM applications. Engineers will appreciate its ease of integration, advanced communication options, and reliable performance in demanding industrial environments.
