Product Overview

IS400JPDHG1ABB and IS410JPDHG1A belong to GE JPDG series pack power distribution boards designed for Mark VIe and Mark VIeS Speedtronic turbine control systems. IS410JPDHG1A is the standard production version, while IS400JPDHG1ABB is an engineering derivative variant used for special project configurations.

This board acts as a central DC power hub inside the Mark VIe control rack. It accepts 28VDC control power input and distributes stable regulated power to up to 24 I/O packs plus 3 Ethernet network switches. Each output channel is protected by PTC self-resetting fuses to prevent overload damage to downstream I/O modules. It supports redundant power architecture, which is critical for gas turbine and steam turbine safety control. The PCB uses conformal coating to resist dust, moisture and vibration in power plant cabinet environments.
