Functional Description
IS200JPDDG4A is a Power Distribution Board developed by GE. It is a part of Mark VIe control system. The dc Power Distribution (JPDD) board serves as a critical component in distributing and managing dc power within the control system environment. Its primary functions include power distribution, power isolation, and branch circuit protection, catering specifically to devices that rely on either 125 V dc or 24 V dc power sources.
Features
- Applications: Finds application in various scenarios such as providing power for dc relay and solenoid control, as well as facilitating contact wetting. These functionalities are essential for the operation of control or I/O functions within the system.
- Output: Each output on the board is equipped with a fuse, a switch, and an indicator lamp. These components collectively ensure efficient power management, circuit protection, and visual feedback regarding the presence of output voltage, enhancing the safety and reliability of the system.
- Limitations: It's important to note that the board is not designed for power distribution to the I/O packs. Its scope is primarily focused on powering specific control or I/O functions that require 125 V dc or 24 V dc power, emphasizing its role as a dedicated power distribution unit within the control system architecture.
Configuration
Configuring the dc Power Distribution board involves primarily checking and adjusting the position of the six output load switches. These switches play a crucial role in determining the distribution of power to various branch circuits within the system.
- Load Switch Adjustment: Ensure that the six output load switches are set to the appropriate positions based on the specific requirements of the system. Proper positioning of these switches is essential for efficient power distribution and circuit protection.
- Fuse Compatibility: While the board comes with standard fuse ratings, it is possible to use other fuse ratings to accommodate specific branch circuit requirements. Compatible fuses, such as the Bussmann ABC series with ratings ranging from 1⁄4 A through 15 A, can be utilized for this purpose.
- Important Considerations: Avoid using fuses with ratings exceeding 15 A, as they are not compatible with the board's design and may pose safety risks. If alternate fuse ratings are chosen, ensure that the appropriate fuse is inserted into each branch circuit to maintain proper circuit protection and functionality.
Input Connections
- 125 V dc Input: Utilizes a 2-pin connection to receive input power from JPDx or another JPDD with a maximum rating of 15 A. This input serves as a primary power source for the JPDD board.
- 24 V dc Input: Features a 4-pin connection for receiving input power from JPDx or another JPDD with a maximum rating of 30 A. This input provides an alternative power source, complementing the 125 V dc input.
- Auxiliary Power Input: Accommodates auxiliary power input through TB2, offering additional flexibility in power supply options.
Output Connections
- Power Outputs (6x): Each output features a 2-pin connection for delivering power to TRLY or TBCI devices, supporting both 24 V dc and 125 V dc applications. These outputs are fused to ensure circuit protection and reliability.
- 125 V dc Output: Provides a 2-pin connection for output power to another JPDD board, facilitating daisy-chaining or cascading of power distribution within the system.
- 24 V dc Output: Features a 4-pin connection for output power to another JPDD board, enabling seamless integration and expansion of the power distribution network.
