General Electric DS200TCPDG2B DS200TCPDG2BEC Power Distribution Board

GE DS200TCPDG2B (DS200TCPDG2BEC) power distribution board is a key component in GE's industrial control systems. It is primarily responsible for managing and distributing power to ensure the normal operation of each board in the system. The power distribution board receives 125 V DC power and distributes it to several important components, such as the TCPS board in each I/O core, the control engine core, the TCEA board in the P1 core, the DTBC and DTBD terminal boards in the digital core for solenoid valve output power, and indirectly powers the digital I/O cores (Q11, Q21, and Q51).

It also manages 120/240 V AC power and converts it to 125 V DC through a DACA converter. For systems that require lower voltages, power conditioning is available through specific connections. In addition, it has a single core shutdown switch for easy system maintenance and troubleshooting, and a CTBA terminal board in the R5 core to monitor PD power output. In terms of applications, it is widely used in GE's Mark VI and Mark VIe turbine control systems to ensure power distribution to gas and steam turbine control systems.

Features

• Power Distribution: The TCPD board receives 125 V DC power and distributes it to important components such as:
• TCPS boards in each I/O core.
• Control Engine core.
• TCEA board in P1 core.
• DTBC and DTBD terminal boards in the digital core for solenoid output power.
• Digital I/O cores (Q11, Q21, and Q51), but indirectly powered by their associated I/O cores.
• AC Conversion: It also manages the 120/240 V AC power supplied to the ignition transformer connected to the DTBC terminal board. The board converts the AC power to 125 V DC using a DACA (AC to DC) converter using the JZ2 connector.
• Power Conditioning: For systems that require lower voltages (e.g., contact #18 on the DTBC board in the Q51 core), an optional JZ3 connection can be used. Power is further conditioned through resistors using the JZ1 connector and then distributed to the TCEA board in the P1 core.
• Individual Core Shutdown: The board includes switches for shutting down each core individually, providing safety for system maintenance and troubleshooting.
• Terminal Block Monitoring: The CTBA Terminal Block in the R5 core monitors the PD power output and receives power from the TCPD board.

application

The following are the main application areas and functions of DS200TCPDG2B:

1.Gas and Steam Turbine Control Systems

DS200TCPDG2B is used in Mark VI and Mark VIe turbine control systems developed by GE. These systems are used for power plant management and control of gas and steam turbines. It ensures the correct distribution of power to key components such as the control engine core, I/O core, and other related boards.

2.Power Distribution in Control Systems

The board distributes 125 V DC power to various subsystems, including:

TCPS board in each I/O core.

Control Engine Core (responsible for executing control algorithms).

TCEA board in P1 core.

It also provides power to DTBC and DTBD terminal boards in the digital core, which are used for solenoid output power.

3. Digital I/O Core Power Management

While the DS200TCPDG2B does not directly power the digital I/O cores (Q11, Q21, and Q51), it plays a role in ensuring that these cores receive power indirectly through their associated I/O cores.

4. Ignition Transformer Power

This board provides 120/240 V AC to the ignition transformer connected to the DTBC terminal block.

This is critical for the ignition system in a gas turbine, as ignition is essential for startup and operation.
