FUNCTIONAL DESCRIPTION OF IS200JPDFG1ACA :

IS200JPDFG1ACA is a DC Power Distribution Module (125 V) designed and manufactured by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The 125 V dc power distribution module JPDFG1ACA accepts redundant 125 V dc power inputs and distributes power to other system boards. JPDF works with a floating DC bus 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 JPDFG1ACA module. The power is then routed through a 125 V dc 30 A circuit breaker and line filter, and then connected to the JPDFG1ACA board via 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 JPDFG1ACA 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 JPDFG1ACA module is base-mounted vertically on a metal base located inside the PDM cabinet. For safety and grounding purposes, it is essential to establish a proper connection between the JPDF sheet metal and the system’s protective earth (PE). The input battery power is supplied to the module via the DCHI (positive) and DCLO (negative) terminals. When the system includes one or two DACA modules, AC power is typically supplied through connector JAF1, often sourced from an IS2020JPDB module. The DACA modules connect to the JPDF board using connectors JZ2 and JZ3, facilitating the flow of AC power, which is then converted to DC and reintegrated into the power system.

In setups utilizing a PPDA power diagnostic I/O pack, a 50-pin ribbon cable is required to connect the P1 connector on the JPDF module to the P2 connector on the board that houses the PPDA. This ribbon cable enables the communication of diagnostic and power monitoring signals. If needed, this connection can be extended through other core PDM boards using additional P2 connectors, maintaining a unified power distribution and diagnostics chain across the system.

GROUNDING:

Mark VIe systems divide ground into a protective earth (PE) and a functional earth (FE). The PE ground must be connected to an appropriate earth connection in accordance with all local standards. The minimum grounding must be capable of carrying 60 A for 60 seconds with no more than a 10 volt drop. The FE ground system must be bonded to the PE ground system at one point. 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 the 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 from the surface upon which it is mounted. This is done specifically to allow definition of the JPDF ground independent of the mounting surface. Typically, JPDF is mounted to a back 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.

GROUND FAULT DETECTION:

The module supports the use of a dc bus that is centered on ground potential by a high resistance. This arrangement allows the detection of a ground fault when the positive bus or negative bus voltage goes to ground potential. In support of this arrangement, the JPDFG1ACA includes separate voltage feedback sensing for positive and negative power with respect to ground. When the feedback is cabled into a PPDA I/O pack, detection of ground faults is provided to the system. The resistance used to center the dc bus on ground sets the ground detection sensitivity and ground fault currents that can flow. IS200JPDF contains centering resistors selected by jumper JP1. Should centering resistance be provided elsewhere, then the jumper on JPDF should be open. JPDF is designed to then insert minimal centering resistance in the system. If JPDF is providing the centering function, JP1 should be closed. If two JPDF modules are used, only one should have a closed JP1 jumper.

FREQUENTLY ASKED QUESTIONS:

What is GE IS200JPDFG1ACA?

The IS200JPDFG1ACA is a 125 V DC Power Distribution Module manufactured by General Electric (GE) for the Mark VIe control system. It accepts redundant 125 V DC power inputs and distributes power to other control system components through protected, fused output circuits. The module also provides power monitoring and diagnostic functions, including DC bus voltage monitoring, ground-fault detection, and fused branch status feedback through a connected PPDA I/O pack.

What are the primary power input sources for the module?

The module accepts redundant 125 V DC inputs typically sourced from battery banks. These inputs are applied to terminals DCHI (positive) and DCLO (negative). Additionally, the module can receive 115/230 V AC power through connector JAF1, which is routed to external DACA modules. The DACA units then convert the AC to DC and feed it back into the module, providing a dual-source input structure that enhances reliability.

How is the input power conditioned before distribution?

DC power first passes through a 30 A circuit breaker, offering protection against overloads and short circuits. The power then flows into a filter assembly located beneath the circuit board, which eliminates electrical noise and voltage spikes. After filtering, it passes through a series of diodes that prevent reverse current flow, protecting the board and connected systems from potential damage due to power backfeed.

How is AC power integrated into the module's operation?

When AC input is used, it is applied via the JAF1 connector and routed internally to connectors JZ2 and JZ3, which interface with DACA modules. These modules convert the AC input into 125 V DC. The resulting DC output is returned to the PDM through the same JZ2 and JZ3 connectors. This DC is then combined with any battery-sourced DC power to create a robust, redundant power supply.
