ABB IMHSS03 Valve Position Control Hydraulic Servo Module

Description

The IMHSS03 Hydraulic Servo module is a valve position control module. It provides an interface through which a Harmony controller can drive a servo valve or I/H converter to provide manual or automatic control of a hydraulic actuator.

Features

• Advanced Control Algorithms: Incorporates advanced control algorithms and optimized design to provide precise control of position, speed, and torque.
• Compatibility: Works with the IMFCS01 Frequency Counter module in most applications.
• Intelligent I/O Module: Equipped with an onboard microprocessor, memory, and communication circuitry.
• Current Regulation: By regulating the current to the servo valve, the IMHSS03 module can initiate a change in actuator position.
• Position Feedback: A linear variable differential transformer (LVDT) provides actuator position feedback to the hydraulic servo module.

Applications

Typical uses for the IMHSS03 module include positioning of steam turbine throttle and control valves, gas turbine fuel valves, inlet guide vanes, and nozzle angle. As the valve opens or closes, it regulates fuel or steam flow to the turbine, thus controlling the turbine speed.
