GE IS220PTURH1A Primary Turbine Trip Module
$205.00
$420.00
Description
The GE IS220PTURH1A is a primary turbine protection I/O pack designed for the GE Mark VIe Speedtronic turbine control system. It interfaces with turbine protection signals and supports speed monitoring, overspeed detection, and emergency trip logic. The listed configuration includes three pulse-rate or speed inputs, dual redundant Ethernet ports, and compatibility with specified turbine control terminal boards.
Function and Signal Processing
The IS220PTURH1A processes turbine protection inputs and interfaces with the primary turbine trip logic. Its speed-monitoring function accepts signals from passive or active pickups, allowing the control system to monitor shaft speed and evaluate overspeed conditions. The supplied specifications also identify support for Geiger-Muller or optical flame detection sensor interfaces.
The module uses a dual ARM Cortex processor architecture and provides dual redundant 100Base-TX Ethernet ports for communication with the Mark VIe control system. The Ethernet configuration provides two network connections; the exact redundancy behavior and network topology should be confirmed against the applicable system documentation.

Terminal Board and Installation Configuration
The IS220PTURH1A mounts on a compatible turbine control terminal board rather than operating as a standalone field-wiring module. The I/O pack connects to the terminal board through a high-density connector, while its Ethernet ports provide the communication interface to the control network. The documented Mark VIe configuration includes the TTURH1C terminal board; GE documentation also identifies an IS200TRPAH1A terminal board combination for specified primary trip applications.
Before replacing an installed unit, verify the terminal board part number, turbine protection architecture, field signal assignments, and controller configuration. A matching module part number alone does not establish that every existing terminal board or system arrangement is compatible.
Frequently Asked Questions
Q: What is the primary function of the IS220PTURH1A?
A: It serves as a turbine-specific primary trip I/O pack in the GE Mark VIe system. It interfaces with turbine protection signals and supports speed monitoring and primary trip functions according to the configured terminal board and control application.
Q: Which terminal board is compatible with the IS220PTURH1A?
A: TTURH1C is a documented associated terminal board. GE documentation also identifies the IS200TRPAH1A combination for specified applications. Confirm the actual terminal board and protection configuration before selecting a replacement.
Q: Can the IS220PTURH1A be replaced without checking the system configuration?
A: No. Verify the exact part number, terminal board, controller configuration, firmware requirements, and signal assignments before replacement. Do not assume that a different revision or another turbine protection I/O pack is interchangeable.
