Description

Product Overview

The IS220PDOAH1B‑E is the Rev E discrete output pack for GE Mark VIe / Mark VIeS turbine control. It communicates over dual IONet Ethernet to the controller and drives field relays, solenoids, trip coils, alarm indicators and auxiliary equipment. It works with matching terminal boards (TRLYH1B/C/D/F for mechanical relays; TRLYH1E for solid‑state outputs), supports simplex, dual redundant and TMR safety architectures widely used on gas / steam turbines and generator BMS.
