FUNCTIONAL DESCRIPTION:
IS200JPDFG1ACA is a 125 V 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 IS200JPDF 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 detecting 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 IS2020JPDF module. The power is then routed through a 125 V dc 30 A circuit breaker and line filter before being connected to the IS200JPDF 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, which are converted to dc power. Dc power returns to JPDF, combined with the battery power input. JPDF can operate with any combination of one or more inputs creating a high-reliability source of 125 V dc power for the control system. The IS200JPDF 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:
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 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 if present.
GROUNDING:
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.
