Functional Description:

The IS2020JPDBG01 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, monitors, and decentralizes AC power. The module contains two line filters and an IS200JPDB board.

The module contains two independent AC power distribution circuits, each rated at 20 A at 115 or 230 V AC.

The input circuits should be wired in parallel to prevent PPDA alarms when only one AC power source is available.

Each circuit has one fuse output and three fuse and switch branch circuit outputs. the JPDF 125 V DC power distribution module has an optional connection.

The IS200JPDB has status feedback for all fuse circuits and passive supervisory circuits for both AC ranges.

On connector P1 is the supervisory circuitry for connecting cables to the board containing the power supply diagnostic PPDA I/O packages.

Port P2 on the IS200JPDB allows monitoring signals from other power distribution system cards to pass through.

Compatibility:

The JPDE, JPDF, JPDS, and JPDM feedback signal P1 and P2 connections on the IS2020JPDB are compatible, resulting in a PPDA I/O package. The AC input on the JPDF module of the same name can be used with connector JAF2.

Installation:

In the PDM cabinet, the IS2020JPDB module is mounted vertically on a metal rear base. The protective grounding 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, input power is delivered to AC2H (line) and AC2N (neutral).

There must be a grounded neutral connection on both AC inputs. Follow the documentation for the system's output circuit connections.

If the distribution system has a PPDA Power Diagnostics I/O package, a 50-pin ribbon cable is required to connect JPDB connection P1 to connector P2 on the board with the PPDA. Other core PDM boards can use the P2 connector for this connection.

Operation:

The terminal block on the right side of the JPDB module has two AC power supplies connected to it. Below the IS200JPDB 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 via the wire harness.

The circuit board for the IS2020JPDBG01 module is the IS200JPDBH1A. since J1 is connected directly to the output branch circuit, this board is not used for AC power selector connections.

The IS200JPDBH2A board is used by the IS2020JPDBG02 module. This board requires an AC power selector.

The JSS1 connector is mounted on one of the boards.JSS1 receives externally filtered AC power from connector J1. To feed the power supply, the branch circuit outputs, and the source selector outputs are returned to JSS1.

The two DACA power conversion modules are powered by JAF1. which feeds power directly from input connector J1 to the adjacent optional JPDF board.

For systems utilizing 125 V DC batteries, the DACA modules are used as an AC backup power supply that converts AC power to 125 V DC power.
