GE IS215VPROH2BC Turbine Protection Plate

The GE IS215VPROH2BC Turbine Protection Board is a device manufactured by General Electric (GE) and is designed for turbine protection applications. Here are the details about this protection board:

1. Main Functions

Emergency Turbine Protection: The IS215VPROH2BC is designed to work as both a turbine emergency trip and a turbine protection board.

Input/Output Processor: Mainly used as an input/output processor board for TPRO and TREG boards.

2. Interfaces and Connections

Interface with TREG Board: When the VPRO model is used with a TREG board, the I/O signal types include energy saving relay, emergency stop input, trip interlock input, and trip solenoid valve driver.

Ethernet Connection: When operating as a turbine emergency trip processor board, it is capable of connecting to the TPRO terminal board via an Ethernet cable.

3. Technical Parameters

Number of I/Os: Each available TREG board has seven trip interlock inputs and three trip solenoid drivers.

Power Supply: Each VPRO board is equipped with its own power supply, using the 125V DC voltage from the cabinet PDM to generate 5V DC voltage and 28V DC voltage.

4. Application and Features

Application Areas: Mainly used in gas turbine applications to provide emergency overspeed (EOS) protection for turbines.

Protection Mechanisms: Includes backup synchronization check protection, three analog current inputs and nine thermocouple inputs for gas turbine exhaust overtemperature protection.

5. Installation and Diagnosis

Installation: Secure the edge connector of the board by sliding in and pushing in the top and bottom levers by hand, and tighten the self-tapping screws at the top and bottom of the front panel.

Diagnosis: The status of the VPRO front panel is indicated by three LEDs on the top, including a flashing green RUN status, a steady red FAIL status, and a steady orange "Status" LED (when a diagnostic alarm condition occurs).
