- By establishing a connection with an I/O pack, the module enables real-time monitoring of critical parameters such as bus voltage, ground faults, and excessive AC voltage on the DC bus. This detailed feedback mechanism empowers proactive maintenance strategies, minimizing downtime and optimizing overall system performance.
- With its floating DC bus and non-hazardous voltage rating, the module cultivates a safe operating environment. This feature underscores the module's commitment to enhancing safety within the control system environment by mitigating electrical risks and providing robust protection for both personnel and equipment.
Installation Procedure
- Secure Mounting: Begin by locating the dedicated PDM cabinet. Inside, identify the designated metal back base. Securely mount the module in an upright position on this base, ensuring stability and minimizing potential vibrations.
- Grounding for Safety: Establish a reliable connection between the sheet metal and the system's protective earth (PE) terminal. This crucial step ensures proper grounding and protects against electrical faults.
- Power Input Options: Locate the designated terminals DCHI and DCLO for your 125V DC battery power. Connect the battery leads carefully, adhering to the correct polarity.
- Integrating DACA Modules (Optional): If your system utilizes one or two DACA modules for AC-DC conversion, connect them to the JPDF board through their respective connectors, JZ2 and JZ3.
- Output Circuit Connections: Provides various output circuits for powering different system components. Consult the overall system's technical specifications to identify the designated connections for each circuit. Ensure correct polarity and voltage compatibility during wiring.
- PPDA Connectivity (Optional): For systems equipped with a PPDA power diagnostic I/O pack, a 50-pin ribbon cable is required. Connect one end of the cable to the JPDF connector P1 and the other end to the P2 connector on the board holding the PPDA unit. This connection, if applicable, may be routed through other core PDM boards using the designated P2 connector path. Ensure optimal cable routing for signal integrity.
Operation
- DC battery power is applied to DCHI and DCLO terminals. 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 diode 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.
Grounding Features
- Mark VIe systems divide the ground into a protective earth (PE) and a functional earth (FE). The PE ground must be connected to an appropriate earth connection by 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 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 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.

Frequently Asked Questions
What is IS200JPDFG1ACA?
It is a power distribution module developed by GE under the Mark VIe series.
Which connector should be used to power TBCI boards when powered by JPDF?
TBCI boards should use connector J12 with a JPDD fan-out board. This connector provides a coordinated 44 ohm source impedance that matches the circuit ratings of TBCI boards.
Which connector should be used to power the TRPG/TREG board pair?
The TRPG/TREG board pair, being critical to system operation, should be powered by the dedicated J7 connector.
When should JP1 be used?
Use JP1 if JPDF is providing bus voltage-centering resistors for ground fault detection.
