Detailed content

Product Description

The GE IS220PTURH1A is a PTUR Turbine-Specific Primary Trip I/O Pack for the GE Mark VIe turbine control system. It provides the electrical interface between one or two I/O Ethernet networks and the associated turbine protection terminal board. The module is designed for primary turbine protection functions including turbine speed monitoring, emergency-stop inputs, trip signals, and other turbine-specific protection functions.

The PTUR pack contains a processor board, turbine-specific control circuitry, and an analog acquisition section. It connects to the turbine terminal board through a DC-62 connector and communicates with the Mark VIe controller through dual Ethernet IONet connections. GE documentation identifies the IS200TRPAH1A as the accessory terminal board for the PTUR module.

The supplied item is identified as IS220PTURH1A Rev D. When replacing an existing module, verify the complete hardware revision, terminal-board type, firmware configuration, and existing Mark VIe architecture before installation.

FAQ

Q: What is the IS220PTURH1A used for?
A: It is a Mark VIe PTUR Turbine-Specific Primary Trip I/O Pack used for turbine protection, speed monitoring, emergency-stop inputs, and related trip functions.

Q: Which terminal board is compatible with the PTUR module?
A: GE documentation identifies the IS200TRPAH1A as the accessory terminal board for the IS220PTURH1A.

Q: Does the PTUR communicate through Ethernet?
A: Yes. The module provides dual 10/100 Ethernet interfaces for IONet communication with the Mark VIe control system.

Q: What does Rev D mean?
A: Rev D identifies the hardware revision of the supplied module. Hardware revision compatibility should be checked against the installed system before replacement.

Q: Can this module be installed without the terminal board?
A: The PTUR is designed to operate as part of the Mark VIe I/O architecture with its compatible terminal board and field wiring. Confirm the complete assembly configuration before installation.

Troubleshooting & Safety

🛠️ No IONet communication: Check both Ethernet connections, network status LEDs, controller configuration, and the associated terminal-board connection.

🛠️ Incorrect speed feedback: Verify magnetic pickup wiring, signal polarity, sensor condition, and the configured speed-input channel.

🛠️ Trip or E-stop fault: Check the associated TRPA field wiring and confirm that the input voltage falls within the applicable specification.

🛠️ Module does not power up: Verify the 28 VDC supply and terminal-board power connections. The documented supply range is 27.4–28.6 VDC.

⚠️ Turbine protection equipment: The PTUR is part of a primary turbine protection system. Replacement work should be performed by qualified personnel following the site’s approved trip and commissioning procedures.

⚠️ Lockout/Tagout: Isolate applicable control and field power before removing the I/O pack or modifying terminal-board wiring.

⚠️ Configuration Verification: Do not substitute a different PTUR revision solely based on physical appearance. Verify the complete part number, revision, terminal board, firmware, and Mark VIe system configuration.
