Allen-Bradley 1756-HYD02 Hydraulic Servo Module

Allen-Bradley 1756-HYD02 Hydraulic Servo Module is a two-axis hydraulic motion controller designed for ControlLogix systems. As a closed-loop hydraulic servo module, it provides two independent axes of hydraulic motion control within a single 1756 backplane slot, translating digital position and velocity commands into hydraulic valve actuation with feedback. The module is intended for use with ControlLogix PLCs in 1756-system configurations to drive precision hydraulic axes in automation tasks requiring accurate positioning and synchronized motion. It is part of the ControlLogix Hydraulic Servo Module family, with documentation noting that the HYD02 supports up to two axes per module and that the product line was discontinued as of March 15, 2024 (1756-HYD02K). When integrating this module, engineers should ensure compatibility with existing 1756 backplane hardware and verify that their hydraulic system can accept dual-axis servo commands. This makes the HYD02 suitable for applications requiring coordinated motion across two hydraulic axes, such as precise linear actuation, clamping or forming sequences, and other automated tasks where reliable closed-loop hydraulic control is essential.
