Allen Bradley 1756-HSC High Speed Counter Module

The AB 1756-HSC is a high-performance High Speed Counter (HSC) module designed for use within the ControlLogix platform. With support for two independent counters, the module provides precise pulse counting and rapid signal processing for demanding motion and positioning applications.

Each counter features A/B/Z differential inputs, supporting gate and reset signals at 5V, 12V, or 24V DC levels. The module also includes four high-speed DC outputs, allowing for responsive control based on encoder feedback or position events. Ideal for electronic position measuring and single-axis positioning, the 1756-HSC ensures deterministic performance in high-speed industrial environments.
