Manufacturer: GE Fanuc
Country of Manufacture: United States(USA)
Availability: In Stock
Product Type: Servo Driver Module (SCB)

Functional Description

IC3600SSVD1L1D is a Servo Driver Module manufactured by GE Fanuc. It is a part of Mark I and II control systems. The primary function of is to drive servo actuators within the turbine control architecture. Servo drivers are essential components that convert low-power control signals into higher-power signals required to operate mechanical actuators. These actuators typically control elements such as fuel valves, variable inlet guide vanes (IGVs), and other turbine components that must be adjusted dynamically during operation.

System Electronic Design Features

• The electronic design of the gas turbine control system is a critical component that resides primarily within the turbine control panel. This panel houses the majority of the control electronics, including vital subsystems such as the microcomputer for the Integrated Turbine System (ITS), power supplies, interfacing relays, and terminal trip wiring terminations. These components collectively manage the precise and safe operation of the turbine by processing input signals, executing control logic, and managing output functions.
• At the heart of the panel is the card page, which is mounted in a roll-out rack for ease of access and maintenance. This page comprises multiple card receptacles, each serving as a slot for inserting individual electronic control cards. The interconnecting wiring for these cards is located on the reverse side of the receptacles and is connected using wire-wrap technology. These connections are meticulously created using a computer-controlled wire-wrapping machine, which follows a computer-generated pattern to ensure accuracy and consistency. The same system that creates the wiring pattern also generates an elementary wiring diagram, offering clear traceability between the logical design and the physical implementation on the backplane. This alignment is crucial for diagnostics and system documentation.
• Power for the control electronics is sourced from the station battery, which provides unregulated DC power. This raw power is then converted by the system’s power supply units into precision-regulated outputs required by the control cards. These power supplies are designed with generous operating margins to ensure low operating temperatures and extended component life. In addition, critical power rails are equipped with short-circuit protection and overvoltage protection to safeguard against failure propagation and protect sensitive components.
• A significant amount of engineering has gone into minimizing the effects of voltage and current transients, which could otherwise lead to component damage or introduce electrical noise into the system. Most of the power supplies within the turbine control panel utilize switching-mode regulators, known for their efficiency and compact size. However, in applications where high-precision voltages are needed, these are often supplemented by follow-on series regulators that provide additional filtering and fine regulation.
