1769-HSC CompactLogix series high-speed counter module

1769-HSC is a CompactLogix series high-speed counter module launched by Allen Bradley brand under Rockwell Automation, designed specifically for high-speed pulse signal processing and motion control in industrial automation scenarios. This module integrates an independent microprocessor and supports single channel 1MHz or dual channel orthogonal encoder input (maximum frequency 200kHz). It can synchronously process 4 pulse/count signals and generate real-time rate and time interval data. It is suitable for scenarios such as machine tool spindle monitoring and logistics conveyor belt speed detection. The highlights of its technical parameters include: 5-30V DC wide voltage input range, 1950 Ω input impedance, pulse width response as low as 259ns, and 131ns phase interval, ensuring precise control of high-speed dynamic processes; The module is installed on DIN rails and complies with the CompactLogix rack standard. The 5V DC backplane current consumption is 425mA, with a power consumption of only 7.5W, making it suitable for dense deployment of control cabinets.

The 1769-HSC has flexible modes such as up/down counting and orthogonal decoding, supports preset value triggering and digital output, seamlessly integrates with the RSLogix 5000 programming environment, and is compatible with industrial protocols such as Profibus DP and EtherNet/IP. It has excellent environmental adaptability, with a working temperature range of -20 ℃ to 60 ℃, storage temperature of -40 ℃ to 85 ℃, relative humidity of 5% -95% (non condensing), and built-in 4000V lightning protection, 1.5A overcurrent protection, and 600W surge suppression function, ensuring stability in harsh industrial environments.

This module is widely used in manufacturing industries (such as CNC machining, packaging production line counting), energy fields (power plant turbine monitoring, water pump station control), and process industries (metallurgical rolling mill control, oil pipeline measurement). Through high-speed data acquisition and real-time communication capabilities, it significantly improves the accuracy and system reliability of production equipment, and is the core component of motion control and process monitoring in industrial automation systems.
