Product Description:

The CM030121210 counter by Danaher has an internal power supply that includes 12 VDC at 175 mA to support peripheral interfacing and sensor integration. This counter has a 6-decade main counter range for accurate and scalable handling of data for heavy counting applications.

Its calibration process is facilitated by a calibrator range of 5 decades, which is adjustable from 0.0001 to 9.9999, allowing for precise tuning of signal simulation and system test. This counter’s totalizer range is also 6 decades, which is suitable for cumulative data monitoring for long periods of operation. This counter has an extensive input voltage range of 85-265 VAC and can also be operated efficiently at a frequency of 50-60 Hz, and this is among the reasons why this counter can be utilized in numerous industrial applications. The CM030121210 supports a maximum input rate of 40 kHz to ensure compatibility with high-speed pulse inputs. This counter features three solid-state control outputs, each with 100 mA sinking current at up to 24 VDC, which makes it ideal for heavy process control without mechanical relay restrictions. The user interface of this counter has an eight-character red LED display, with each of the characters being 0.4 inches high to easily see and instantly read.

There is a six-position sealed tactile keyboard to provide reliable user input, most importantly in industrial environments where responsiveness and durability are crucial. Its status of operation is easily identified using the three built-in annunciators marked as RUN, SET, and PGM, to provide users with visual indications for running, setup, and programming modes. The CM030121210 counter has an RS-485 serial interface for smooth integration into multi-device and long-distance industrial communication networks. At a weight of 308 grams, this counter is light and convenient to install within space-limited control panels or enclosures.
