The Allen-Bradley 1756-HYD02 is a dual-axis hydraulic servo module from the ControlLogix family designed for precise motion control applications. It supports Proportional, Integral, and Derivative (PID) control with feed-forward and directional gain scaling, providing 32-bit floating-point gain resolution for high-accuracy servo tuning. The module offers an absolute position range of up to 230,000 LDT counts with a configurable update rate between 500 Hz and 4 kHz, making it ideal for closed-loop hydraulic motion systems requiring fast response and precise feedback integration.
