GE IS220PDIAH1B (IS230SNCIH2A) Discrete Input Module

Description

TheGE IS220PDIAH1B Discrete Input Module(also referenced asIS230SNCIH2A) is part of the GE Mark VIe control system, providing reliable digital input acquisition for turbine and industrial automation. It captures discrete field signals-such as switches, sensors, and protective relays-and sends their status to the Mark VIe controller. It is widely used in gas, steam, and hydro turbine applications, offering rugged design, noise-immune signal processing, and built-in diagnostics for safe and continuous operation.
