Information About 1756-HSC

The 1756-HSC is part of the Allen-Bradley ControlLogix family, developed to handle high-frequency input signals for real-time counting and measurement. It supports multiple operating modes including counter, rate measurement, encoder, and debounce filter, allowing flexibility in industrial automation systems. Each counter can process signals at up to 1 MHz in counter mode, 500 kHz in rate measurement mode, and 250 kHz in encoder mode, with filtering available for noisy signals. The module includes four configurable outputs, which can be linked to counter presets for rapid activation without requiring controller scan delays. Its count range extends up to 16,214,777, providing precision in applications requiring long or repeated counts. With backplane current consumption of 300 mA at 5V and 3 mA at 24V, and maximum power dissipation of 5.6 W at 60 °C, it is suitable for high-performance environments. Typical use cases include integration with encoders, photoelectric sensors, and proximity switches for accurate speed, position, and event counting.

Key Features:

  • Counters: Two independent high-speed counters with three inputs each (A, B, Z for gate/reset).
  • Input Frequencies: Handles up to 1 MHz in counter mode, 500 kHz in rate measurement mode, and 250 kHz in encoder mode.
  • Operation Modes: Configurable for counter, rate measurement, encoder, and debounce filter modes.
  • Outputs: Four output points (two per group), assignable per counter, with configurable turn-off presets.
  • Count Range: Supports counting up to 16,214,777 for extended or high-volume counting applications.
  • Response Speed: Data updated every 2 ms for rapid output activation and improved system responsiveness.
  • Power Requirements: Backplane draw of 300 mA at 5V and 3 mA at 24V, with 5.6 W maximum dissipation at 60 °C.
  • Integration: Compatible with incremental encoders, photoelectric sensors, and proximity switches for motion and position feedback.

The 1756-HSC delivers precise and high-speed counting performance, making it essential for motion control, speed monitoring, and position feedback in industrial automation systems.

Frequently Asked Questions about 1756-HSC
Question: What is the primary function of the 1756-HSC module?
Date Update:03/06/2025
Answer:

The 1756-HSC is a High-Speed Counter module used in ControlLogix systems. Its main purpose is to count fast incoming pulses from encoders, sensors, or pulse-generating devices in real time. It supports applications such as rotary position detection, linear measurement, flow totalization, and speed detection. This module allows for precise control of position- and speed-based automation processes. It can be used in both frequency and counting modes depending on system needs.

Question: Which terminal blocks are compatible with the 1756-HSC?
Date Update:03/06/2025
Answer:

The 1756-HSC is compatible with removable terminal blocks (RTBs) such as the 1756-TBCH and 1756-TBS6H. These terminal blocks provide connections for field wiring and simplify installation and maintenance. They allow for quick disconnection of the module without rewiring. The RTBs also feature finger-safe terminals to ensure operator safety. Selection depends on your wiring preferences and installation style.

Question: What is the maximum count range for the 1756-HSC?
Date Update:03/06/2025
Answer:

The maximum count range for the 1756-HSC is 0 to 16,777,214 counts per counter. This wide range allows for precise measurement of rotation, position, and event counting in complex applications. The counter can be reset either through external signals or programmatically. This flexibility supports a wide array of industrial applications including conveyor systems, flow meters, and machine positioning. The large range also reduces the chance of count overflow in long-duration operations.

Question: What kind of sensors can be used with the 1756-HSC?
Date Update:03/06/2025
Answer:

The 1756-HSC module is compatible with devices such as encoders, proximity sensors, photoelectric sensors, and magnetic pickup sensors. It works well with Allen-Bradley’s 845 incremental encoders and 872 proximity switches. These sensors generate pulses that are counted and analyzed by the module. Accurate feedback from sensors ensures reliable monitoring and control. The module is ideal for applications involving motion, speed, and position sensing.

Question: Is the 1756-HSC still in production?
Date Update:03/06/2025
Answer:

Yes, the Allen-Bradley 1756-HSC module is currently still in production. It remains part of the active ControlLogix product family and is supported by Rockwell Automation. The module continues to be widely used in modern industrial automation systems that require high-speed pulse counting. However, Rockwell recommends checking product lifecycle status periodically for updates. Replacement modules or enhanced versions may become available in the future.
