IS200JPDSG1A - PWR DISTRIBUTION CARD

IS200JPDSG1A is a 28 V Power Distribution Board manufactured and designed by General Electric. It is a part of the Mark VIe Series used in distributed control systems. The 28 V Power Distribution (JPDS) board provides the control system with 28 V dc input power from external ac/dc or dc/dc converters. JPDS incorporates feedback from the PPDA I/O pack into the PDM system.

Comapatibility

• The JPDB, JPDF, and JPDE feedback signal P1/P2 connections on the board can be connected to create a PPDA I/O pack.
• This I/O pack is compatible with the DC-62 connector on JPDS.

Installation

• JPDS is mounted in a metal holder that slides onto a vertical DIN-rail next to other power distribution boards. JPDS can also be ordered with an optional metal holder that is intended for direct mounting.
• On the top and bottom of the board, there are 50-pin diagnostic connectors installed.

Grounding

• The IS200JPDS board is grounded to the underside of the back base through the sheet metal bracket. This can typically be the system FE.

IS200JPDSG1A Operation

The power distribution board, or JPDS, is what transfers 28 V dc power from the chosen power sources to the JPDP boards (for powering the I/O packs) and control racks. JR, JS, and JT connectors are used to provide the conventional 28 V power input to JPDS.

• JR, JS, and JT are three 28 V power input connectors. There are two positive connections and three negative connections on the power supply connectors. Three power supply health inputs with two dry contact inputs for each power source are also present; these signals serve as diagnostic signals.
• J1, J2, J3, J4, J5, and J6 six-pin connections provide six outputs to JPDP cards (3x2 Mate-N-Lok). The pin assignments on this connector match those of JPDP exactly. To supply the I/O packs, JPDS can be directly connected to up to six JPDL boards.
• Each of the three outputs JAR, JAS, and JAT has a common-mode choke for noise reduction and a positive temperature coefficient fuse for current limiting.
• Utilizing separate screw terminals on TB1 and TB2, the internal 28 V bus is reachable at the top and bottom of the board. The maximum continuous current capacity for the screw terminals for R, S, and T is 35 A. You can connect boards together using these terminals. For ground, a 75 A screw terminal is specified.
• PPDA power diagnostic I/O pack DC-62 connection. The 50-pin diagnostic ribbon cable connecting JPDS to the PPDA allows the PPDA to monitor JPDS as well as up to five additional power distribution boards.
