IS2020JPDFG02 is a Power Distribution Module developed by GE. It is a part of mark VI control system. The module offers full status feedback, meaning it continuously provides real-time information on various aspects of the power distribution system. This feedback is crucial for operators and maintenance personnel to monitor the health and performance of the system. It establishes a connection to a PPDA I/O pack, which acts as an interface for collecting and processing data from multiple modules within the power distribution network. This integration ensures seamless communication and data exchange between the module and other components of the system.
- The component is to monitor the magnitude of the bus voltage. By continuously measuring the voltage level, it ensures that the power distribution system operates within the desired voltage range. Deviations from the normal voltage levels can trigger alarms or corrective actions to prevent potential issues.
- It is equipped with ground fault detection capabilities. It continuously monitors the power distribution system for any leakage currents or unintended paths to ground. The timely detection of ground faults is essential for preventing electrical hazards, protecting equipment, and ensuring the safety of personnel.
- In certain power distribution systems, it is crucial to detect any excessive AC voltage on the DC bus. The module is designed to identify such anomalies and raise alerts if AC voltage levels on the DC bus exceed safe operating limits. This ensures the integrity of the DC bus and associated equipment.
- The product monitors each fused branch circuit individually. By doing so, it can indicate the presence of output power for each circuit accurately. This capability helps operators identify faulty or malfunctioning branches and take appropriate actions to maintain uninterrupted power distribution.
- Designed with excellent compatibility, facilitating seamless integration into power distribution systems. It is engineered to work effortlessly with feedback signal connectors, P1/P2, found on various modules such as JPDB, JPDE, JPDS, and JPDM, all leading to a PPDA I/O pack. This compatibility ensures smooth communication and data exchange between the module and other interconnected components within the power distribution network, enhancing the overall system's efficiency and reliability.
- The product features connector JAF1, which is specifically tailored to be compatible with the ac power output on the module. This seamless compatibility allows for a direct connection between these modules, enabling it to receive the necessary power input, ensuring its proper functioning and operation.
- It is equipped with connectors JZ2 and JZ3, which are specifically designed to be compatible with the connectors. This compatibility enables a smooth and direct connection between these modules, facilitating the exchange of data and signals between them. The collaboration between the JPDF and DACA modules ensures efficient data processing and accurate monitoring within the power distribution system.
- Optimized Power Allocation: Ensures that the generated power from the turbine is distributed efficiently to various subsystems and components, such as sensors, actuators, control panels, and communication devices. This allocation of power is essential to ensure that each component receives the appropriate amount of electricity it needs to operate effectively.
- Safety and Circuit Protection: Safety is paramount in turbine control systems, as any malfunction or failure can have serious consequences. Incorporates circuit protection mechanisms like fuses, circuit breakers, and overcurrent protection to prevent damage to components due to electrical faults or overloads.
- Centralized Control: With the PDM serving as a centralized control point, operators can manage the activation and deactivation of different subsystems and components easily. This centralized control simplifies the operation of the turbine and allows for efficient troubleshooting in case of any issues.
- Redundancy and Reliability: Turbine control systems often require high levels of reliability and redundancy to ensure uninterrupted operation. Can be designed with redundant power paths, allowing the system to switch to an alternative power source in case of a failure, thereby enhancing overall system reliability.
- Remote Monitoring and Management: Some PDM in turbine control systems may support remote monitoring and management. This remote accessibility enables operators to oversee the power distribution, perform diagnostics, and even initiate maintenance tasks without being physically present at the turbine site.
- Integration with Control Logic: Integrated into the overall control logic of the turbine system. This integration enables the system to respond dynamically to changes in power demand, load fluctuations, and other operational factors.
Power Source Features
- A dependable power supply for the rack power units is ensured through a combination of sources, which include a battery, multiple power converters, or a blend of both. These diverse power sources are interconnected in a high-select configuration within the Power Distribution Module (PDM) to ensure essential redundancy.
- To create a stable floating DC bus while maintaining a single ground connection, a balancing resistor network is employed. Starting from the 125 V DC input, this resistor bridge generates two vital voltage outputs: +62.5 V DC, referred to as P125, and -62.5 V DC, referred to as N125. These voltages are utilized to power the system racks and terminal boards effectively.
- The PDM also incorporates ground fault detection capabilities, enhancing safety and reliability. In the event of a single ground fault occurrence, the system remains operational without any performance degradation, and fuses remain intact. This fault is promptly alarmed, allowing for timely repair and maintenance.

Frequently Asked Questions
What is IS2020JPDFG02?
It is a Power Distribution Module developed by GE
How does the module handle power inputs and distribution?
The module accepts two redundant 125 V DC power inputs. The input battery power is connected to a terminal board. It then passes through a 125 V DC 30 A circuit breaker and a line filter before being connected to the board through the J1 connector. The module routes DC voltage to three fused, non-switched outputs, and six fused, switched outputs.
How does the component work with the floating DC bus system?
It operates with a floating DC bus centered on earth, rather than using a grounded system. This configuration enables the detection of system ground faults and ensures a non-hazardous live 125 V DC rating, enhancing safety and reliability.
What is the role of the DACA modules in the power distribution process?
The module routes AC power through the board to the DACA modules, where it is converted to DC power. The converted DC power returns to the module and is combined with the input battery power.
How many power inputs can the board handle?
The module is designed to operate with any combination of one or more inputs active. This capability allows for high-reliability power distribution, ensuring continuous operation even if one input source is unavailable.
