Description
Product Overview
The GE IS200TSVCH2AED, with secondary part number MRP246517, is a servo valve terminal board for GE Speedtronic Mark VI and Mark VIe turbine control systems. It acts as the physical interface between the control I/O pack and field electro-hydraulic servo valves. It receives control commands from the main controller and sends drive signals to valve actuators. It also captures LVDT position feedback signals to form closed-loop valve regulation. This board directly controls fuel and steam valve movement for gas and steam turbine units.
Precise valve control decides turbine stability and output accuracy. Ordinary terminal boards often suffer weak signal shielding. They easily pick up electromagnetic interference inside power plant cabinets. Noise distorts LVDT feedback and causes valve hunting or position drift. These faults may reduce unit efficiency or trigger unexpected trips. To solve these risks, the GE IS200TSVCH2AED uses optimized signal filtering and barrier terminal design. Every unit passes full channel calibration and vibration screening before shipment. It supports rack installation and fits standard industrial e-commerce spare part procurement workflows.
Core Product Features & Competitive Advantages
Turbine servo loops demand fast response and high signal fidelity. Generic wiring boards cannot meet the strict closed-loop control requirements of turbine valve systems. In contrast, the GE IS200TSVCH2AED is custom-built for Mark VI / Mark VIe servo control architecture. It integrates servo drive output, LVDT excitation and position signal acquisition on one PCB.
