Product Overview

The IS230JPDMG1B is a GE Mark VIe power distribution module for the control system’s 28 V DC supply. GE identifies this assembly as a JPDM power distribution board used with a PPDA diagnostics I/O pack. The JPDM board accepts three DC supply inputs and routes protected power to downstream distribution boards, controllers and auxiliary devices. Its R, S and T power buses can serve separate control channels. The board also passes bus-voltage, supply-status and fuse-status information to the PPDA pack, giving the power distribution system a defined feedback path rather than acting as a passive junction point.

Technical Specifications

Features

• Three 28 V DC power-supply inputs
• Separate R, S and T power buses
• Fused outputs for distribution boards and controllers
• Filtered, self-resetting fused auxiliary outputs

Industries Served
-Power Generation: Distributes control power within GE Mark VIe turbine-generator control cabinets, where separate supply paths and power-status feedback are important to system operation.
-Oil and Gas: Suits Mark VIe-controlled turbine and compressor packages that use multiple DC supply paths for control equipment.
-Industrial Process Plants: Supports facilities running GE Mark VIe control systems for on-site generation, mechanical drives or associated plant equipment.

Frequently Asked Questions

1. What does IS230JPDMG1B do?
It distributes 28 V DC power to parts of a GE Mark VIe control system and provides power-system feedback through the PPDA diagnostics pack.
2. How many DC supply inputs does the JPDM board have?
GE documents three 28 V DC supply input connections, associated with the R, S and T power paths.
3. Does the module provide feedback about power distribution?
Yes. The documented JPDM arrangement sends bus-voltage readings, supply-status information and fuse-status signals to the PPDA pack.
4. Are its downstream outputs protected?
Yes. GE specifies fused outputs for distribution-board and controller-power circuits, plus self-resetting fuse protection for auxiliary outputs.
