Product Details
The IMHSS03 Hydraulic Servo Module is a valve position control module used in an INFI 90 ® system to control the speed of a turbine. It interfaces a servo valve or an I/H converter to an IMMFP01, IMMFP02 or IMMFP03 Multi-Function Processor Module. The multi-function processor (MFP) module controls the position of a steam or gas turbine throttle valve by sending a position demand to the hydraulic servo (HSS) module. The HSS module drives its outputs to open or close the throttle valve to match the position demand. The MFP module uses the IMFCS01 Frequency Counter Module to measure the turbine speed. The frequency counter module measures turbine speed by counting and timing pulses from a magnetic pickup on the turbine shaft. The MFP module uses this count to calculate turbine speed and calculate a new demand based on a set point.
The IMHSS03 module is a compatible replacement of the IMHSS01 or IMHSS02 module and offers improved performance. The IMHSS03 module automatically tunes its demodulator gain, offering a more optimal response.
The following are its main features and functions:
Functions and Features
| Valve Position Control: The IMHSS03 is a valve position control module that controls the throttle position of steam or gas turbines in conjunction with a multi-function processor module (such as IMMFP01, IMMFP02 or IMMFP03). |
| High Precision Control: The module is capable of high precision and high response speed motion control, with a control accuracy of ±0.1% and a response speed of less than 10ms. |
| Automatic Feedback Gain Adjustment: The IMHSS03 can automatically adjust the feedback gain to optimize the dynamic response characteristics. |
| Compatibility: The module is backward compatible with IMHSS01 and IMHSS02 servo cards. |
Technical Parameters
| Input signal: supports analog or digital input, such as 4-20mA, 0-10V. |
| Output signal: hydraulic signal, used to control the opening of the hydraulic valve. |
| Power supply voltage: 24V DC. |
| Operating temperature range: 0°C to 55°C. |
| Protection level: IP20 |
Advantages
| Use industrial-grade components to ensure long-term stable operation. |
| Flexible configuration: can be flexibly configured through software to adapt to different application requirements. |
| Easy to integrate: seamlessly integrated with ABB's Harmony control system |
