GE IS2020JPDBG01 PDM, AC POW. DIST. W/O SOUR.SE

Part Number IS2020JPDBG01 Manufacturer General Electric Country of Manufacture As Per GE Manufacturing Policy Series Mark VI/VIe Function Module Availability In StockIS2020JPDBG01 is a Power Distribution Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The JPDB board for ac power distribution regulates, watches over, and disperses ac power. Two line filters and an IS200JPDB circuit board are included in the module. Two separate ac distribution circuits, each rated for 20 A at 115 or 230 V ac, are included in the module. To prevent PPDA alerts when only one source of ac power is available, the input circuits should be wired in parallel. There is one fused output and three fused and switched branch circuit outputs for each circuit. There is a connection available for a JPDF 125 V dc distribution module that is optional. The IS200JPDB features status feedback for all fused circuits as well as passive monitoring circuits for both ac magnitudes. On connector P1, which is suitable for cable connection to a board containing a power diagnostic PPDA I/O pack, are the monitoring circuits. The P2 port on the IS200JPDB allows monitoring signals from other power distribution system cards to be passed through.

COMPATIBILITY: The JPDE, JPDF, JPDS, and JPDM feedback signal P1 and P2 connections on the IS2020JPDB are compatible, creating a PPDA I/O pack. The ac input on the JPDF module bearing the same name can be used with connector JAF2. INSTALLATION: In a PDM cabinet, the IS2020JPDB module is base-mounted vertically on a metal rear base. The Protective Earth system and the IS2020JPDB sheet metal must be connected. For the first ac circuit, input power is delivered to terminals AC1H (line) and AC1N (neutral), and for the second ac circuit, AC2H (line) and AC2N (neutral). There must be grounded neutral connections on both ac inputs. The system's output circuit connections follow the documentation. A 50-pin ribbon cable is needed to link the JPDB connection P1 to the P2 connector on the board housing the PPDA if the power distribution system has a PPDA power diagnostic I/O pack. Other core PDM boards may be connected by using the P2 connector for this connection. OPERATION: A terminal board on the right side of the JPDB module has two ac power sources linked to it. Under the IS200JPDB circuit board, the ac power is directed to the ac line filter assembly. The J1 connector on the JPDB circuit board is connected to the filter assembly by a wire harness.

The circuit board for the IS2020JPDBG01 module is the IS200JPDBH1A. Since J1 is attached directly to the output branch circuits, this board does not have a connection for an ac source selector. The IS200JPDBH2A circuit board is used by the IS2020JPDBG02 module. An ac source selector is required for use with the board. The JSS1 connector is mounted to the board in it. JSS1 receives external filtered ac from connector J1. To power, the branch circuit outputs, the source selector output returns to the JSS1. Two DACA power conversion modules are powered by JAF1 directly feeding power from input connector J1 to a neighboring, optional JPDF board. For use as an ac backup for systems using a 125 V dc battery, the DACA modules convert ac power to 125 V dc.
