1756-HSC/B Functional Description

The 1756-HSC/B HSC module Allen-Bradley is a high-speed counter module designed for the ControlLogix platform, delivering precise counting capabilities for demanding industrial applications. This dual-channel module operates with a rapid 0.05 ms response time and features 24V DC inputs alongside four digital outputs, enabling real-time monitoring and control of high-speed processes. Its robust chassis-mount design ensures reliable operation in temperatures ranging from 0 to 60 degrees Celsius.

A key characteristic of the AB 1756-HSC/B I/O Module is its versatile operating modes, supporting frequency measurement, rate calculation, and encoder input processing. The module achieves counting speeds up to 1 MHz in counter mode and handles quadrature encoder signals at 250 kHz, making it suitable for precision motion control applications. This performance allows it to accurately track position and speed parameters in complex automation systems.

The AB 1756-HSC/B HIGH-SPEED COUNTER MODULE offers significant advantages through its local processing capability, which offloads counting tasks from the main controller. This architecture provides faster response times for output activation compared to controller-based evaluation. The module's 36-pin configuration supports multiple input types including A, B, and Z channels for comprehensive encoder interface and precise position referencing.

Engineered for seamless integration, the ROCKWELL 1756 SERIES ControlLogix 1756-HSC/B works optimally with Allen-Bradley 845 incremental encoders and various sensor types. Its user-configurable presets and extensive count range up to 16 million ensure flexibility across different applications. The proven reliability of the HIGH-SPEED COUNTER MODULE Allen Bradley 1756-HSC/B makes it an essential component for high-speed counting in packaging, material handling, and precision machining applications.
