+86 18020776786Hydraulic Servo Module · Harmony Rack Turbine Control
ABB IMHSS03 is a Hydraulic Servo module for Harmony Rack turbine-control applications. ABB describes it as a valve-position-control module that provides an interface through which a Harmony controller can drive a servo valve or I/H converter for manual or automatic control of a hydraulic actuator. The controller uses function code 55 or 150 to configure and access the module’s input and output channels. Selection should be based on the complete model designation and the confirmed role in the installed ABB system, not on a shortened name, product appearance or an assumed equivalent.
ABB lists typical uses including steam-turbine throttle and control valves, gas-turbine fuel valves, inlet guide vanes and nozzle angle. The module regulates current to the servo valve and receives actuator-position feedback from a linear variable differential transformer (LVDT). ABB describes IMHSS03 as an intelligent I/O module with onboard microprocessor, memory and communication circuitry; it commonly works with the IMFCS01 Frequency Counter module. Correct installation requires review of the actual turbine-control design, termination unit, jumper and switch configuration, wiring, controller application and safety procedure. A quotation request should include the required quantity, destination, a clear nameplate photograph and the relevant installed-configuration evidence so the exact requirement can be reviewed before order confirmation.

ABB identifies IMHSS03 as a Hydraulic Servo module for Harmony Rack turbine-control applications.
It is a valve-position-control module through which a Harmony controller can drive a servo valve or I/H converter for manual or automatic hydraulic-actuator control.
ABB specifies function code 55 or 150 for configuring and accessing the module input and output channels.
Compatibility depends on the actual Harmony controller configuration, termination unit, servo interface, LVDT feedback arrangement, wiring and application program. Verify all of these before replacement.
ABB lists steam-turbine throttle/control valves, gas-turbine fuel valves, inlet guide vanes and nozzle-angle applications.
ABB specifies one module-mounting-unit slot, a cable to the termination unit and field wiring on the termination unit. Follow the applicable ABB procedure and approved turbine-control safety steps.
