Allen-Bradley 1756-HSC/B ControlLogix High Speed Counter Module 2-Channel
Product Description
The Allen-Bradley 1756-HSC/B is a high-performance ControlLogix® High-Speed Counter (HSC) module engineered for deterministic counting and frequency measurement in rapid industrial processes. This Series B module effectively offloads complex counting tasks from the controller's main processor, processing input signals at frequencies up to 1 MHz. This hardware-level processing is critical for applications where the PLC scan time is too slow to accurately capture high-speed events.
Featuring two independent 32-bit counter channels, the 1756-HSC/B supports various input modes, including quadrature encoders, pulse/direction, and up/down counting. It also incorporates four onboard high-speed digital outputs, which can be configured to trigger immediately based on reaching specific count values (windows or presets), providing near-instantaneous control response for position and velocity applications.
