Product Overview
The GE IS220PDIOH1B is a discrete I/O pack module for GE Mark VIe turbine control systemsGE Vernova. It features an integrated local processor and data acquisition circuitry to handle field digital input signals and drive discrete output commands for turbine auxiliary devices. Dual Ethernet ports provide high‑speed communication with the Mark VIe controller network. It pairs with external terminal boards such as IS220TDBSH2A, IS220TDBSH8A, IS220TDBTH2A, IS220TDBTH8A for field wiring termination. This module is widely deployed as replacement spare for existing gas and steam turbine control retrofits.
