GE IS220PDIOH1B Discrete I/O Pack | Mark VIe Speedtronic Turbine Control Module

Description

Product Overview

GE IS220PDIOH1B is a discrete I/O pack for GE Mark VIe Speedtronic turbine control system. Equipped with local onboard processor, it provides 24‑channel dry‑contact discrete inputs and 12‑channel Type‑C mechanical relay outputs. Dual IONet industrial Ethernet ports are integrated for system communication. It works with compatible terminal boards such as ISx0YTDBSH2A and ISx0YTDBSH8A to acquire field digital signals and drive interlock relays. Front‑panel LED indicators display power, network and channel fault status. This hardware technology is OEM obsolete. New surplus stock and fully‑tested refurbished spare parts are available for legacy gas & steam turbine control system maintenance and replacementhoneywell
