Description
1. Product Title
GE IS200TSVCH2AED – Servo Control Terminal Board
2. Product Overview
The IS200TSVCH2AED s a high-precision Servo Control (TSVC) terminal board designed for the GE Mark VI and Mark VIe control systems. Its primary function is to provide the physical interface for controlling electro-hydraulic servo valves, which are responsible for modulating fuel and steam flow in turbine applications. This board, often identified by the assembly part number MRP246517, manages the critical feedback loop between the controller and the turbine’s actuators. By facilitating the connection for Linear Variable Differential Transformers (LVDTs) or Rotary Variable Differential Transformers (RVDTs), the <span style=”color: blue;”>IS200TSVCH2AED</span> ensures accurate positioning of valves. It solves the complex industrial challenge of maintaining tight process control over high-pressure hydraulic systems while providing essential electrical isolation and signal conditioning.
