Product Details:

The GE IS220PPDAH1B, part number 336A5026ADP14, is a high-reliability Power Distribution Feedback Module (PPDA) designed for GE Speedtronic Mark VIe distributed turbine control systems. This industrial control spare part monitors and conditions power circuit feedback signals from JPDC, JPDS, JPDM series power distribution terminal boards. As a reliable Turbine Control Module, it collects AC and DC power status signals, ground fault feedback and fuse loss signals inside the control rack. It converts raw power monitoring signals into digital data and transmits real-time power health information to the main controller through dual IONet Ethernet ports. It can detect power branch overload, blown fuse and ground fault conditions to protect the whole turbine control rack for gas turbines and steam turbines.

The GE IS220PPDAH1B Power Distribution Feedback Module is equipped with dual 10/100Mbps IONet Ethernet ports for redundant network communication, supporting hot swap maintenance without shutting down the system. Front panel LED indicators show module running status, network link and power fault alarms. It adopts conformal coated PCB to resist dust, moisture and vibration in harsh power plant environments. Built-in multi-channel self-diagnostic functions continuously monitor feedback circuit status and report power abnormality faults timely. The module supports simplex, dual and TMR redundant system architectures and I/O rack mounting inside Mark VIe control cabinet. It is widely used in power generation and oil & gas industries for turbine control system maintenance, spare part replacement and system retrofit.
