ABB SPHSS13 Hydraulic Servo Module

ABB SPHSS13 Hydraulic Servo Module

Product overview

ABB SPHHS13 is a high-performance hydraulic servo module designed specifically for industrial hydraulic control systems, belonging to ABB's rich industrial automation product line. It is mainly suitable for Harmony Rack systems and plays a key role in many industrial scenarios. For example, in terms of turbine control, it can accurately regulate the opening of the steam valve of the turbine, effectively control the speed and output power of the turbine, and ensure stable power output; In wind turbine control, the pitch angle can be precisely adjusted based on environmental factors such as wind speed to achieve efficient utilization of wind energy. In addition, among various industrial automation equipment that require strict precision in position, speed, and torque control, SPHHS13 can also demonstrate its capabilities, providing strong support for the stable operation and precise control of the equipment.

Specification parameters

Physical specifications: The module size is exquisite, with a length of 297.18mm, a height of 35.56mm, a width of 175.26mm, and a weight of approximately 0.272kg or 0.28kg. This compact design enables it to flexibly adapt to various spatial conditions during equipment installation and layout, greatly reducing the occupation of internal space of the equipment and reducing the overall load of the equipment, which is conducive to efficient operation and convenient maintenance of the equipment.

Electrical parameters: The rated input voltage has good compatibility, generally 24V DC, and some data shows that it also supports 48V DC, with a power consumption of 25W. This electrical parameter design not only meets the power requirements for stable and efficient operation of the module itself, but also works within a reasonable energy consumption range, meeting the dual requirements of energy conservation and stable operation in industrial production.

Environmental adaptability parameters: The working and storage temperature ranges from -40 ° C to+85 ° C, demonstrating strong temperature adaptability. It can operate stably in both harsh outdoor environments and high-temperature industrial workshops. The protection level reaches IP67, with excellent dustproof and waterproof performance, which can effectively resist the erosion of external factors such as dust and water vapor, adapt to various harsh and complex industrial environments, ensure reliable operation under extreme working conditions, and maintain stable system operation.

Core functions

Redundant design ensures reliability: Equipped with redundant servo coils, this design is a key manifestation of its high reliability. During normal operation, two servo coils work together. When one coil fails due to electrical short circuit, overheating, or other reasons, the other coil can quickly and seamlessly take over the work, ensuring uninterrupted system control signals, maintaining stable operation of the hydraulic system, effectively avoiding system shutdown caused by key component failures, greatly improving the reliability and fault tolerance of the system, ensuring the continuity of industrial production, and reducing economic losses caused by equipment failures.

Multi sensor support: compatible with AC and DC linear variable differential transformers (LVDT). LVDT, as a high-precision displacement sensor, is commonly used in industrial production to accurately measure the position changes of mechanical components. SPHSS13 can adapt to different types of LVDTs and flexibly select the most suitable sensor for precise measurement and control based on actual measurement scenarios and accuracy requirements, providing rich choices for accurate measurement and control, meeting diverse measurement and control needs in complex industrial environments, and ensuring precise monitoring and control of hydraulic systems.

Flexible control mode: It has two control modes: proportional integral (PI) and pure proportional (P). In PI control mode, the module can effectively eliminate system static errors through proportional and integral calculations of system deviations, making the control process more precise and stable. It is particularly suitable for scenarios that require extremely high control accuracy and long-term stable operation, such as hydraulic control systems for precision machine tools. The pure proportional (P) control mode has an extremely fast response speed and can quickly adjust the control quantity according to changes in the system input signal. It plays a key role in situations where response speed is demanding and sudden changes need to be quickly responded to, such as hydraulic control of high-speed stamping equipment. It can quickly and accurately adjust the control strategy according to actual working conditions.

Working principle

Signal input and processing: External control signals, such as command signals from the automation control system, as well as real-time status signals of the hydraulic system detected by various sensors (such as position signals fed back by LVDT sensors, pressure signals transmitted by pressure sensors, etc.), are input together into the SPHHS13 module. The signal conditioning circuit inside the module will preprocess these input signals, such as filtering to remove noise interference from the signal, amplifying the signal amplitude to an appropriate range, ensuring the accuracy and stability of the signal, and providing reliable data basis for subsequent precise control operations.
