Product Overview

The GE IS230JPDMG1B is a JPDM power distribution board used in Mark VIe control cabinet power distribution (PDM) assemblies. Its primary role is to accept 28 VDC input power from external conversion supplies and distribute protected DC power to controllers and cabinet loads. In addition to power routing, the board provides status/feedback signaling to an associated I/O pack so the control system can monitor bus health and fuse conditions.

This module supports multiple DC buses and can be applied in configurations requiring either independent buses or redundancy via jumper-selected arrangements, depending on the cabinet design and wiring scheme.

Hardware Parameters

Key Technical Characteristics

• 28 VDC cabinet power distribution for Mark VIe PDM architectures

• Three-bus design supporting segmented power routing (R/S/T) and flexible cabinet builds

• Jumper-selectable bus tying to implement redundant supply arrangements where required

• Fused load feeds to reduce fault propagation and support maintainable cabinet protection practices

• Integrated feedback signaling to the monitoring I/O pack for bus state and power condition visibility

• Expandable wiring approach enabling interconnection between adjacent distribution boards (cabinet dependent)

Industrial Applications

• Turbine and generator control cabinets using Mark VIe power distribution modules for DC load feeding

• Distributed control system power panels where continuous monitoring of DC buses improves availability

• Redundant DC supply designs requiring bus paralleling or dual-source configurations (as engineered)

• Maintenance replacement for PDM cabinets where like-for-like JPDM board interchange is required
