Functional Description

DS200TCPDG1AFC is a power distribution module developed by GE. It is a part of the Mark V control system. The power distribution module (TCPD), located in the PD core, manages and distributes power within the control system architecture. It serves as a central hub for providing 125 V DC power to various components across different cores.

Features

• One of its primary functions is to supply power to the TCPS boards located in each I/O core, the Control Engine core (R), and the TCEA boards in the P1 core. This distribution ensures that these critical components receive consistent and reliable power supply for uninterrupted operation.
• The board is equipped with switches that enable individual shutdown of each core, offering flexibility in power management and maintenance operations. This capability allows for efficient handling of power-related issues without affecting the entire system.
• However, it's important to note that the digital I/O cores (Q11 and Q51) do not draw their power directly from the PD core. Instead, these cores receive their power from their associated I/O cores (R1 and R5, respectively). This setup ensures that digital I/O operations remain independent yet synchronized within their respective subsystems.
• For the solenoids and wetted contact inputs on the DTBA, DTBC, and DTBD terminal boards in the Q11 and Q51 cores, the TCPD board serves as the primary power source. This ensures reliable operation of these input devices critical for control and monitoring functions.
• Additionally, the TCPD board supplies 120/240 V AC power specifically for the ignition transformers, which are essential for initiating processes within the system. This voltage supply is crucial for ensuring proper ignition and operational readiness of related equipment.
• In the R5 core, the CTBA terminal board relies on the board for its 5 V power supply. This voltage is necessary for powering specific components and subsystems within the core, ensuring stable and consistent performance.

Hardware Configuration

• The board incorporates essential hardware configurations to manage power distribution effectively within the control system architecture. One notable feature is the BJS hardware jumper, designed specifically for systems with an external reference.
• The BJS hardware jumper serves a critical role in isolating the ground reference for systems equipped with an external reference. When the jumper is installed, it ensures that the ground reference is provided, facilitating proper operation and synchronization of external reference systems. 

Software Configuration

• The board is characterized by its simplicity in operational setup, particularly in terms of software configuration.
• Unlike some other components within the control system, the board does not require any software configuration. This design choice minimizes complexity during installation and maintenance, focusing instead on hardware-level adjustments and operational settings.

Frequently Asked Questions

What is DS200TCPDG1AFC?
It is a Power Distribution Module developed by GE under the Mark V series.

How does external AC power enter the control system?
External 115/230 V AC power is introduced into the control system through the TB1 terminal board, which is mounted on the PD core. This terminal board serves as the entry point for hard-wiring AC power connections to the Power Distribution Module board.

How is AC power converted to DC voltage within the control system?
Upon entering the control system, the AC power is converted to 125 V DC voltage. This conversion process occurs through a DACA (AC to DC) block, which is integrated into the system and facilitates the transformation of power sources. The DACA block manages this conversion seamlessly to ensure consistent DC voltage output.

What is the role of the JZ2 connector in the power distribution process?
The converted 125 V DC signals are then transmitted to various cores and boards within the control system via connectors, including the JZ2 connector. This connector acts as a pathway for distributing DC voltage signals to ensure that each component receives the necessary power supply for operation.
