ABB SPHSS13 Hydraulic Servo Module

ABB SPHSS13 (often referred to as a Bailey SPHSS13) is a specialized hydraulic servo module, serving as a core component in advanced industrial 

automation and DCS (Distributed Control System) architectures. It is specifically designed to interface with and control hydraulic actuators, providing high-speed, 

high-precision closed-loop control.

Built for demanding industrial environments, this module features redundant servo coils and supports redundant AC or DC LVDT (Linear Variable Differential Transformer) 

feedback, ensuring uninterrupted operation and enhanced system safety. It offers flexible control algorithms, including both Proportional-Integral (PI) and Proportional (P-only) 

control modes, allowing for precise tuning to eliminate static errors and achieve optimal stability and responsiveness across various operating conditions.

Its robust construction ensures excellent resistance to vibration, shock, and electromagnetic interference (EMI), making it ideal for heavy industries such as metal processing, 

power generation, and manufacturing. The SPHSS13 seamlessly integrates with ABB control systems like the 800xA and AC800M controllers, providing a reliable 

and efficient solution for managing complex hydraulic processes.
