The IS220PDIAH1A REV J is a state-of-the-art Discrete Input Module used in GE Mark VIe turbine control systems. Built to meet the rigorous demands of power generation and industrial automation environments, this module delivers rapid detection and reliable processing of binary input signals from field devices such as push buttons, relays, and switches.

Designed for seamless integration into GE’s advanced Mark VIe platform, the IS220PDIAH1A facilitates the monitoring of digital states — such as open/closed or on/off — across multiple channels. Each of these channels is optically isolated, ensuring excellent noise immunity and safeguarding the system from voltage transients that are common in industrial operations.

The module is part of GE’s I/O pack system and connects to the control network via the IONet Ethernet protocol. This real-time, high-speed communication system enables deterministic control and efficient signal transmission, which are vital for the safe and precise operation of turbines and other critical infrastructure.

The IS220PDIAH1A REV J supports hot-swap functionality, allowing users to replace the module without halting system operations. This significantly reduces downtime during maintenance or upgrades and contributes to system reliability. The unit also features front-facing LED indicators that display real-time status for each input channel, aiding in system diagnostics and troubleshooting.

Engineered to work with compatible terminal boards such as the STTB (Simplex Terminal Board) or TTUR (Turbine Terminal Board), the IS220PDIAH1A ensures a secure and organized connection to field wiring. The design supports easy configuration via GE’s ToolboxST software, offering engineers a comprehensive suite of tools for system setup, monitoring, and diagnostics.

As a component of the GE Mark VIe system, this module is extensively deployed in turbine control, process automation, and safety interlock systems where high reliability, fast response, and secure signal handling are essential. Its durable construction makes it well-suited for challenging industrial conditions such as those found in gas, steam, and hydro power plants.
