Functional Description
IS400JPDDG1ABB is a Power Distribution Board developed by GE. It is a part of the Mark VIe control system. The JPDD (DC Power Distribution and Protection) board serves as a vital component for distributing, isolating, and safeguarding power for control or I/O functions requiring either 125 V DC or 24 V DC power. The board efficiently distributes DC power to various control or I/O functions within the system. It provides isolation between different circuits to prevent interference and ensure reliable operation.
Features
- Branch Circuit Protection: To safeguard connected devices and components, each output on the board is equipped with a fuse, a switch, and a lamp indicator. These components serve to protect against overcurrent conditions and provide a visual indication of the presence of output voltage.
- Applications: Typical applications include providing power for DC relays, solenoids, contact wetting, and other similar control or I/O functions. It is designed to meet the specific power requirements of such applications, ensuring proper functionality and performance.
- Connectivity Options: The board features two 2-pin Mate-N-Lok connectors for 125 V DC power distribution. One connector serves as the input for receiving power, while the other can be used to daisy-chain power to another JPDD board, simplifying installation and wiring.
- Additionally, two 4-pin Mate-N-Lok connectors are provided for 24 V DC power distribution. These connectors offer similar functionality to the 2-pin connectors but allow for parallel connection of two pin-pairs, enabling increased current capacity as needed.
- Grounding Considerations: It is important to note that neither side of the DC power input is expected to be grounded, ensuring proper system operation and compliance with safety standards.
Configuration
- Output Load Switches: The board features six output load switches, which determine the availability of power to connected devices or circuits. Verify the position of these switches to ensure proper power distribution and protection.
- Fuse Ratings: While the board comes equipped with standard fuse ratings, such as those from the Bussmann ABC series ranging from 1⁄4 A through 15A, it allows for flexibility in fuse selection. If specific branch circuit ratings are required, alternative fuse ratings can be used. However, it's crucial to adhere to certain guidelines:
- Fuse Compatibility: Only fuses compatible with the board should be utilized. The Bussmann ABC series of fuses are recommended, with ratings up to 15A.
- Avoidance of High-Amp Fuses: Fuses with ratings exceeding 15A should not be used with the board. This helps prevent overcurrent situations and ensures the safety and integrity of the board and connected devices.
- Configuration Procedure:
- Fuse Insertion: Insert the appropriate fuse into each branch circuit based on the desired rating. Ensure that the selected fuses match the specifications and requirements of the connected devices or circuits.
- Verification: Once the fuses are inserted, verify that the configuration aligns with the intended branch circuit ratings and load requirements. Ensure proper seating of the fuses to guarantee effective protection against overcurrent conditions.
Outputs
- Each output circuit includes two fuses, one on each side of the DC path. These fuses provide protection by interrupting the circuit in case of overcurrent or short-circuit conditions, preventing damage to the board and connected components.
- A switch is integrated into each output circuit, featuring a pair of isolation contacts on each side of the output. These contacts ensure that both sides of the circuit can be isolated, enhancing safety during maintenance or in the event of a fault. The switch allows for manual control of the circuit, enabling it to be easily disconnected when necessary.
- Each output circuit is equipped with a green lamp that indicates the presence of voltage across the output terminals. This visual indicator helps in quickly identifying the status of the circuit, ensuring that operators can easily verify if the circuit is live or not.
- The design of the output circuits, with a fuse and switch contact on each side of the DC path, allows for the use of floating power sources. This means that the board can be safely used with power supplies that are not referenced to a common ground, providing flexibility in various applications.
