GE FANUC IS220PPDAH1A Power Distribution System Feedback Unit
Description
The GE FANUC IS220PPDAH1A is a Power Distribution System Feedback Unit belonging to the Mark VIe series, designed for use in gas turbine control systems. As a core component of power distribution modules, it offers comprehensive system feedback and monitoring capabilities, with a functional abbreviation of PPDA. The unit accepts input from up to six switchboards, providing real-time feedback for critical power system metrics including ground fault detection, high-capacity power health, power bus voltage, and branch circuit status. It supports corrective action by sending and reporting system data, though it does not provide direct protective measures for connected circuits. Key hardware specifications include five analog inputs and eight LED indicators located on the distribution module for visual status monitoring. The unit is a power distribution feedback system board assembly, referenced in technical manual GEH-6721L. Notably, branch circuits are not directly connected to the PPDA component, ensuring focused feedback without direct circuit interface. This unit is engineered to deliver centralized, multi-point power system visibility, supporting efficient monitoring and maintenance of complex power distribution setups.
