Description

Overview

GE IS220PTURH1A is a Mark Vie series primary turbine specific trip board (PTB). It monitors the speed of the gas turbine and, when a dangerous overspeed is detected, issues a high-priority trip signal, shutting down the unit safely and protecting the turbine itself and surrounding personnel and equipment.

Note: IS220PTURH1A can be used for the control and protection systems of GE Frame 6B, 7E, 7F, 9E, 9FA series gas turbines and steam turbines.

More About Us

🚀Function & Features

Primary Overspeed Trip Signal: The IS220PTURH1A board generates a primary overspeed trip signal for emergency shutdown by analyzing the speed signal from a magnetic sensor.

Four Magnetic Speed Sensor Inputs: The IS220PTURH1A supports connecting up to four passive magnetic speed sensors (magnetoresistive sensors).

Median Selection Logic: The IS220PTURH1A board uses a "median signal selection" algorithm to select the middle value from multiple sensor signals for speed control and overspeed protection.

Auto-Reconfiguration: When a board is replaced, if this feature is enabled in the ToolboxST software, the new board automatically downloads all necessary configuration parameters and firmware from the Mark VIe controller upon power-up.

Questions & Answers

💡 FAQ

How is this board installed?

It is not a standalone module. It plugs vertically into a dedicated termination board, model TTURH1C. All power, sensor signals, and communications are connected to this termination board via the connector on the back of the board.

What is the "Auto-Reconfiguration" feature? Why is it important?

Auto-Reconfiguration" is a critical feature. When a new PTUR board is installed and powered on, if this feature is enabled, it automatically downloads all necessary firmware, application programs, and configuration parameters from the Mark VIe controller.

What should pay attention to if replace the PTUR board?

The system must be in a safe state and follow the correct power-off and power-on procedures. Confirm that the model and version number (IS220PTURH1A) of the new board are exactly the same as the old board.

What could be the reason it reports "Sensor Failure"?

Possible causes include:

The sensor itself is damaged.
The sensor circuit is open (broken wire) or shorted.
The gap between the sensor and the measuring gear is incorrect.
The terminal blocks on the terminal board (TTURH1C) are loose.
