🔹 Product Description

The GE IS220YTURS1A is a Mark VIe YTUR Turbine Specific Primary Trip I/O Pack designed for turbine protection and primary trip functions. The YTUR module works with compatible Mark VIe turbine protection terminal boards, with GE documentation specifically identifying the IS200TRPAS1A as an accessory terminal board. The YTUR architecture incorporates an I/O pack CPU, turbine I/O application board, and turbine I/O daughterboard, providing the processing and interface hardware required for the associated turbine-specific protection system. The module operates from a nominal 28 VDC supply and is designed for an ambient operating range of approximately -30°C to 65°C.

⚙️ Main Functions

• Provides turbine-specific primary trip I/O processing within a GE Mark VIe control system.
• Supports primary turbine protection functions associated with the YTUR architecture.
• Interfaces with the compatible IS200TRPAS1A primary trip terminal board.
• Processes field-side turbine trip and protection signals through its associated terminal-board architecture.
• Incorporates dedicated turbine I/O application and daughterboard circuitry.
• Supports removable terminal-board and I/O-pack servicing.
• Uses the YTUR functional designation for identification within the Mark VIe I/O family.
• Designed for industrial turbine control environments with a nominal 28 VDC supply.

❓ Frequently Asked Questions

Q1: What is the GE IS220YTURS1A?
A: It is a Mark VIe YTUR Turbine Specific Primary Trip I/O Pack used for turbine protection and primary trip functions.

Q2: Which terminal board is associated with IS220YTURS1A?
A: GE documentation identifies the IS200TRPAS1A as the accessory terminal board for the IS220YTURS1A.

Q3: What does YTUR mean?
A: YTUR is the functional designation used by GE for the Turbine Specific Primary Trip I/O Pack.

Q4: What is the nominal power supply?
A: The documented nominal supply is 28.0 VDC, with a specified range of approximately 27.4 to 28.6 VDC.

Q5: Is IS220YTURS1A the same as a standard discrete I/O pack?
A: No. YTUR is a turbine-specific primary trip/protection module rather than a general-purpose discrete I/O pack.

Q6: What should be checked before replacement?
A: Verify the complete part number, hardware revision, associated terminal board, system configuration, and existing turbine protection architecture before installation.
