GE DS200TCPDG1BCC Power Distribution Module

الوصف

The GE DS200TCPDG1BCC is a Power Distribution Module (Functional Acronym: TCPD) designed by General Electric for their Speedtronic Mark V Turbine Control System series.¹

Its primary function is to manage and distribute 125 VDC power to the different system cores and crucial control boards within the Mark V control panel.²

⚙️ Function and Power Distribution

This board is a critical component located in the <PD> core of the Mark V system, responsible for maintaining stable power throughout the control architecture.

Key Power Distribution Targets:

• System Cores: It distributes ³$125 \text{ VDC}$ power to the Control Engine core and the TCPS (Power Supply) boards in each of the I/O cores (e.g., R1, R2, R3).⁴
• Protection Core: It supplies power to the TCEA (Emergency Overspeed) boards in the protective <P1> core.
• Output Boards: It directly powers terminal boards like DTBC and DTBD for solenoid outputs and other signal terminals like DTBA for wetted contact inputs in the digital cores.⁵
• AC Distribution: It also supplies ⁶$120/240 \text{ VAC}$ power for components like the ignition transformers.⁷

Core Isolation Feature

A key operational feature is the inclusion of toggle switches (typically 8) on the board’s surface, which allow maintenance personnel to individually power down each core for troubleshooting or repair without fully shutting down the entire system.⁸

✨ Features and Specifications

The DS200TCPDG1BCC is designed with protective and diagnostic components for high-reliability industrial use:

If you need to perform maintenance, remember to consult the official GE documentation for the correct fuse type and rating to ensure system integrity.
