GE DS200TBQDG1ACC Extension Analog Termination Board

الوصف

The GE DS200TBQDG1ACC is an RST Extension Analog Termination Board (PCB) used in the General Electric Mark V Speedtronic Turbine Control System.¹ Its main purpose is to provide the physical connection point for field-wiring signals to the Mark V control system’s main processing boards.

Board Function and Role

This board is a critical part of the input/output (I/O) interface for the turbine control system, particularly for the extended analog signals.

• RST Designation: This refers to the Triple Modular Redundant (TMR) nature of the Mark V system, which uses three independent control cores (R, S, and T) for enhanced reliability.² The termination board handles the field wiring for signals that are sent to or received from the associated R, S, and T core components.

   

• Termination: It acts as a rugged interface between external field devices (like sensors and actuators) and the more sensitive internal electronics. This is where the physical wires from the turbine are “terminated” via screw connections.³

   

• Protection: The board typically includes protective components, such as Metal Oxide Varistors (MOVs), to guard the control circuitry against excessive voltage surges from the field.⁴

   

• Signal Type: While the specific signals can vary by application, this type of board handles Analog signals, which typically include inputs like position signals (e.g., from LVDTs) and outputs for control.
