The GE IS220PTURH1A Turbine‑Specific Primary Trip Module is a key protection component within the Mark VI Speedtronic control platform. It provides primary trip logic, speed‑related protection, and secure interfacing between turbine terminal boards and Ethernet‑based control networks. Its modular construction and auto‑reconfiguration capabilities ensure reliable operation in gas and steam turbine applications where Mark VI systems remain in service.

The IS220PTURH1A module provides primary turbine trip protection by interfacing directly with Mark VI terminal boards and communicating over Ethernet. It houses three internal boards—processing, turbine control, and analog acquisition—to manage trip logic, speed detection, and analog signal handling. The module supports auto‑reconfiguration through Toolbox ST, enabling automatic firmware and parameter loading from the controller.
