Core Function

PPDA power distribution feedback I/O pack for Mark VIe turbine control system. It is installed on JPD series power distribution board, responsible for real‑time monitoring of DC power bus, fuse state and ground fault signals inside the control rack. It transmits power‑supply diagnostic data to main controller via redundant IONet bus, realizes early warning of power‑loop abnormality. It supports plug‑and‑play replacement without manual re‑configuration. It applies to simplex and TMR triple‑modular redundant turbine control configuration, improves power‑supply fault visibility for the whole control rack and enhances unit operation safety.

Product Details

The IS220PPDAH1B with part number 336A5026ADP14 belongs to PPDA series power distribution feedback I/O pack for GE Speedtronic Mark VIe turbine control system.

This compact plug‑in daughter board cooperates with JPDM, JPDC or JPDS power distribution base board to collect multi‑group power‑bus feedback signals, including fuse blow‑out detection and ground‑fault monitoring. Dual IONet redundant Ethernet uploads all power‑supply status and fault information to Mark VIe main controller, so operators can locate power‑loop risks in advance before hardware failure causes turbine trip. Built‑in electronic ID chip realizes automatic system identification, supports hot‑swap plug‑and‑play replacement, simplifies on‑site maintenance work. Front‑panel LED indicators clearly display module power, network communication and channel fault conditions for quick inspection. Conformal coated circuit board improves anti‑vibration, moisture‑proof and anti‑electromagnetic‑interference performance, adapts to harsh working conditions of power‑plant turbine cabinet. Widely deployed in simplex and TMR triple‑modular redundant gas‑steam turbine control cabinets.

It belongs to critical power‑supply monitoring spare‑part for Mark VIe turbine control system, widely used in overhaul and renovation projects of power generation units.

It is important spare hardware for power‑distribution loop debugging and defective IS220PPDAH1B module replacement.
