The IMHSS03 hydraulic servo module is a valve position control module for controlling turbine speed in the INFI 90? system. It connects the servo valve or I/H converter to the IMMFP01, IMMFP02 or IMMFP03 multifunctional processor module.

The Multi-function processor (MFP) module controls the position of the steam or gas turbine throttle by sending position requirements to the hydraulic servo (HSS) module. The HSS module drives its output to open or close the throttle to meet the position requirements.

The multifunctional digital composite module uses the IMFCS01 frequency counter module to measure turbine speed. The frequency counter module measures turbine speed by counting and timing pulses from magnetic pickups on the turbine shaft. The multifunctional digital composite module uses this count to calculate turbine speed and calculate new requirements based on set points.

This application illustrates how easy it is for PLC users to start adopting PLC-based control system architectures, “said Knud Jansen, Product Manager, Machine Control and Automation, ABB Automation Products. “The key drivers of NTK are the ability to program in a high-level structured text language, as well as powerful code analyzer tools – which provide the company’s software developers with immediate feedback as they develop and test PLC code modules.”
NTK’s PLC crane control system is installed in a protected cabinet located in the cab. However, PLCS are equally available in “best conditions” variants, allowing users to configure functional PLC solutions that are also best suited to operate in harsh conditions and best climates – this is common in some crane and winch applications, for example.
