Products Description
GE IS220PPDAH1B Mark VIe Power Distribution Assembly I/O Pack in stock
GE IS220PPDAH1B is a packaged power distribution assembly I/O pack for GE Mark VIe Speedtronic turbine control system. It monitors power bus health, voltage status and ground fault signals for the rack’s I/O modules and power supply boards, and sends diagnostic data to the main controller via IONet.
This module is compatible with JPDS, JPDC and JPDM power boards, supporting AC analog feedback and ground fault detection. It adopts conformal coating for harsh industrial environments and supports automatic reconfiguration after replacement. It is discontinued legacy spare widely used for gas and steam turbine control cabinet maintenance in power plants.
