FUNCTIONAL DESCRIPTION:
IS400JPDFG1A is a 28V DC Power Distribution Module manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The 125 V dc power distribution module accepts redundant 125 V dc power inputs and distributes power to other system boards. JPDF works with a floating dc bus that is centered on Earth rather than with a grounded system. This permits detection of a system ground fault and carries a non-hazardous live 125 V dc rating. Input 125 V dc battery power is connected to a terminal board on the module.
The power is then routed through a 125 V dc 30 A circuit breaker and line filter before being connected to the board through the J1 connector. Dc voltage is then routed to three fused, non-switched outputs and six fused, switched outputs. Ac power is routed through the board to the DACA modules, where it is converted to dc power. Dc power returns to JPDF, where it is combined with the battery power input. JPDF can operate with any combination of one or more inputs active, creating a high-reliability source of 125 V dc power for the control system. The module provides full status feedback using a connection to a PPDA I/O pack. Feedback includes bus magnitude, ground fault detection, and detection of excessive ac voltage on the dc bus. Each fused branch circuit is monitored to indicate the presence of output power.
INSTALLATION:
The module is base-mounted vertically on a metal base in a cabinet used by the PDM. A connection must be made between the module sheet metal and the system protective earth (PE). Input battery power is applied to terminals DCHI and DCLO. If one or two DACA modules are used, ac power is applied to JAF1, typically from a module. DACA modules connect to JPDF through connectors JZ2 and JZ3. Output circuits are connected as documented for the system. A power distribution system featuring a PPDA power diagnostic I/O pack requires a 50-pin ribbon cable from JPDF connector P1 to the P2 connector on the board holding PPDA. This connection can pass through other core PDM boards using the P2 connector.
COMPATIBILITY:
The module is designed to ensure seamless integration within the turbine control system and is fully compatible with the feedback signal connectors P1 and P2 found on various interface modules, including JPDB, JPDE, JPDS, and JPDM. These connections are routed to the PPDA I/O pack, facilitating accurate signal transmission and real-time data acquisition. Additionally, connector JAF1 on the module aligns with the AC power output interface of the IS2020JPDB module, ensuring stable and reliable power delivery. For further connectivity, the module includes JZ2 and JZ3 connectors, which are specifically engineered to match corresponding mating connectors on the module, enabling efficient plug-and-play installation and system scalability. This compatibility enhances overall system flexibility, simplifies maintenance, and reduces installation time in complex industrial environments.
GROUNDING:
The JPDF is grounded through metal mounting supports fastened to the underlying sheet metal of a metal module. The ground is applied to the metal switch bodies on JPDF. Additionally, the ground is used as a local reference point when creating the feedback signals appearing on P2. The sheet metal of the module is insulated to the surface upon which it is mounted. This is done specifically to allow the definition of the JPDF ground independent of the mounting surface. Typically, JPDF is mounted to a base grounded to FE. JPDF would be located low in the cabinet, and a separate ground wire from the JPDF module would be provided to PE. The minimum length of the ground wire is important to keep impedance low at radio frequencies, allowing the input line filters to function properly.
OPERATION:
DC battery power is applied to terminals DCHI and DCLO. It then goes through a 30 A dc circuit breaker into a filter assembly located under the IS200JPDF circuit board. Filtered output is then passed through a series of diodes to the JPDF circuit board. Ac power is applied to the JAF1 connector. The 115/230 V ac is routed to two connectors, JZ2 and JZ3, and out to two DACA modules. The DACA modules convert the ac power to 125 V dc. The dc power returns to JPDF through the same JZ2 and JZ3 connectors and is combined with battery power if present.

What is the operating voltage range of the module?
The module is designed to operate on a nominal 28V DC supply, with a typical input range of 18V to 32V DC. This allows it to accommodate slight voltage fluctuations without compromising system performance.
How many output channels does it support?
It supports 4 to 16 individually fused output channels. This flexibility allows the module to power multiple subsystems or loads in a distributed control setup, while offering circuit-level protection.
What protections are included in the module?
The module offers integrated overcurrent, short circuit, and ground fault protection. Fused outputs protect connected devices, while the system continuously monitors for grounding issues and voltage anomalies.
Can the module accept AC input power?
Yes. AC power is routed through the JAF1 connector to DACA modules, which convert 115/230V AC to 125V DC. The DC output from DACA is then fed back into the distribution module through connectors JZ2 and JZ3.
