GE IS220PDOAH1B I/O Packet Module
GE IS220PDOAH1B
1. Product Overview
The IS220PDOAH1BC is a discrete output I/O pack module manufactured by General Electric (GE) for the Mark VIe control system. It is designed to connect the I/O Ethernet network with dedicated discrete output terminal boards, enabling signal transmission and control between controllers and field devices. As a core component of the GE Speedtronic Mark VIe gas turbine control system, this module belongs to the IS220 series of I/O modules.
The IS220PDOAH1BC can be used in conjunction with the IS230SNRLH2A (DIN rail relay output module assembly) and the IS200SRLYH2AAA (simplex relay output terminal board) to form a complete Mark VIe discrete output control assembly package.
