Functional Description
IS200JPDAG1AB is a Local AC Power Distribution board developed by GE. It is a part of Mark VIe series. The local AC power distribution board is a component in control systems, providing reliable AC power distribution, power isolation, and branch circuit protection for various control and I/O functions that require AC power. The board distributes AC power to multiple control and I/O functions within the system. This ensures that all necessary components receive the power they need to operate effectively.
Features
- Power Isolation: Each output on the board includes a switch that allows for power isolation. This feature is critical for maintenance and troubleshooting, as it enables safe disconnection of power to specific components without affecting the entire system.
- Branch Circuit Protection: The board provides protection for each branch circuit through the use of fuses. This safeguards the system against overcurrent conditions, prevents damage to equipment and ensures the safety and reliability of the power distribution network.
- Indication of Output Voltage: Each output is equipped with a lamp that indicates the presence of output voltage. This visual indication helps operators quickly verify the status of the power supply to each component, facilitating easier monitoring and troubleshooting.
- AC Relay and Solenoid Control Power: Provides power to relays and solenoids that control various functions within the system. These components are essential for switching and controlling different operations, such as opening and closing valves, and switching electrical circuits.
- Ignition Transformer Excitation: Supplies power to ignition transformers, which are used to generate high-voltage sparks needed for igniting fuels in combustion systems. This application is crucial in systems where controlled ignition is necessary, such as in gas turbines and other combustion engines.
- Contact Wetting: Provides the necessary power for contact wetting, ensuring reliable operation of electrical contacts in relays and switches. Contact wetting is essential for preventing oxidation and ensuring good electrical conductivity.
Installation
- Proper installation of the Local AC Power Distribution (JPDA) board is essential to ensure reliable operation and safety within the control system. It mounts into a specially designed plastic holder that fits securely onto a vertical DIN-rail. To mount, align the plastic holder with the vertical DIN-rail, snap the holder onto the rail ensuring it is firmly secured and properly aligned, and then insert into the plastic holder, making sure it is seated correctly with all mounting points secure.
- The board utilizes three-position Mate-N-Lok connectors for both power input and output cables. These connectors provide a reliable and secure connection for power distribution. To connect the power cables, identify the power input cable and connect it to the designated input Mate-N-Lok connector on the board. Next, identify the power output cables and connect them to the appropriate output Mate-N-Lok connectors. Ensure that all connectors are fully engaged and locked to prevent accidental disconnections. For accurate cable destinations and connections, refer to the system’s circuit diagram, verifying that each cable is connected to the correct input or output position as specified.
- TB1 is designated as the chassis ground connection point. To establish a proper grounding connection, connect a ground lead from TB1 to the system's Protective Earth (PE). This creates a necessary ground path for the metal switch bodies on the board. Ensure that the ground lead is securely fastened to TB1 and the system PE to maintain a reliable ground connection. Double-check all grounding connections to confirm that there are no loose or intermittent connections.
- After completing the installation, perform a thorough check to ensure all connections are secure and correctly made. Test the ground connection to ensure it provides a continuous and effective ground path. Once all checks are complete, power up the system. Observe the indicator lamps to confirm the presence of output voltage, and conduct functional tests on the connected control and I/O components to ensure they are receiving the correct power and operating as expected.
- Proper installation of the board involves secure mounting on a DIN-rail, precise connections using Mate-N-Lok connectors, and effective grounding through TB1. Following these steps ensures that the board operates reliably and safely within the control system, providing essential AC power distribution, power isolation, and branch circuit protection.
Inputs
- AC Input Power Connector: One of the connectors receives AC input power from the JPDM module. This connector is crucial for supplying the board with the necessary voltage to distribute power to its outputs.
- Daisy Chain Connector: The second connector can be used to daisy chain AC power to another board. This configuration allows for a streamlined distribution of power across multiple boards, minimizing wiring complexity and ensuring efficient power management within the system. It is standard practice that the low or neutral side of the input power is grounded, adhering to safety protocols and electrical standards to maintain a secure and stable electrical environment within the control system.
Outputs
- Branch Circuit Protection: Each output circuit is safeguarded by branch circuit protection. This protection mechanism ensures that in the event of an overcurrent or fault condition, the circuit is automatically disconnected to prevent damage to connected devices and ensure system safety.
Isolation Contacts for Non-Grounded Line: A pair of isolation contacts is provided for the non-grounded line of each output circuit. These contacts enable precise control over
- the distribution of power, allowing operators to isolate individual circuits for maintenance or troubleshooting without affecting other parts of the system.
- Voltage Presence Indication: A green lamp is installed across the output terminals of each circuit to indicate the presence of voltage. This visual indicator allows operators to quickly verify the operational status of each output, facilitating efficient monitoring and troubleshooting.
