GE IS215VPROH2BC

1. Product Overview

The GE IS215VPROH2BC (commonly referred to as VPROH2B) is an emergency turbine protection board manufactured by General Electric (GE/Fanuc). As a core module of the GE Mark VI control system series, it is primarily deployed in the emergency overspeed protection systems of gas turbines and steam turbines. Serving as a key component of the turbine protection system, it works in conjunction with TPRO and TREG terminal boards to deliver independent emergency trip functions for turbine equipment.

3. Product Features

Triple Redundancy Design: The IS215VPROH2BC operates with consistent triple redundancy, featuring three completely independent sections (X, Y, and Z). One section can be shut down independently without affecting the normal operation of the entire protection system, ensuring operational stability.
Independent Emergency Overspeed Protection: As a dedicated module independent of the main turbine control system for emergency overspeed protection, it achieves high system reliability and fault safety performance.
Multiple Protection Functions: It integrates diverse protection capabilities, including emergency overspeed protection, exhaust over-temperature protection, analog current input monitoring, and backup synchronization check protection.
Rugged Industrial Structure: Adopting industrial-grade structural design, the module features strong environmental adaptability and can operate stably in harsh industrial working conditions.
Flexible I/O Connection: Compatible with TPRO and TREG terminal boards, it supports up to three trip solenoid drivers to meet diverse control and protection demands.
Dual Power Supply Configuration: Equipped with a dual-sided power supply structure, it provides power redundancy and strong fault tolerance to avoid system shutdown caused by single power failure.
Front Panel Diagnosis Function: Built-in diagnostic indicator lights on the front panel enable real-time and intuitive monitoring of system operating status, facilitating daily inspection and fault troubleshooting.

4. Structure and Composition

4.1 Physical Structure

Front Panel: Integrated with power plugs, Ethernet ID connectors, IONet (Ethernet) ports, and parallel ports and other core connection components.
Rear Panel: Consists of two stacked circuit boards, equipped with multiple vertical connectors and heat dissipation components to ensure stable heat dissipation during high-load operation.
Connector Type: Configured with 5 D-Shell interfaces and 3-pin sub D power connectors for stable signal and power transmission.

4.2 System Architecture

The IS215VPROH2BC is an essential constituent of the Turbine Protection System, with the specific architectural composition as follows:

VPRO Board: The IS215VPROH2BC itself serves as the core turbine protection board to execute main protection logic.
TPRO Terminal Board: Specialized in input and output signal processing for turbine protection scenarios.
TREG Terminal Board: Matched with the VPRO board to realize interface connection and signal transmission of the emergency trip board.

4.3 I/O Signal Types (with TREG Board)

Each TREG terminal board supports 7 trip interlock inputs and 3 trip solenoid drivers, with compatible signal types including:

Energy-saving relay signals
Emergency stop inputs
Trip interlock inputs
Trip solenoid driver signals

5. Application Fields

With high stability and reliable protection performance, the IS215VPROH2BC is widely used in various industrial scenarios requiring turbine and power equipment protection:

Power Plant Industry: Protection of gas turbines and steam turbines in power generation facilities
Steel Industry: Safety protection of power equipment in steel production processes
Cement Industry: Monitoring and protection of large-scale rotating equipment in cement production lines
Shipbuilding Industry: Protection and control of ship power systems
Papermaking Industry: Operational control and safety protection of papermaking machinery
Petrochemical Industry: Turbine safety protection in petroleum and chemical production scenarios
Metallurgical Industry: Safety monitoring and protection of metallurgical production equipment

6. Installation and Maintenance

6.1 Installation Steps

Preparation Work: Shut down the VME I/O processor rack and ensure complete power cut-off to guarantee safe operation.
Module Insertion: Slide the V-board into the rack steadily, and push the top and bottom control levers manually to fix the edge connectors of the module.
Panel Fixation: Tighten the self-tapping screws at the top and bottom of the front panel to secure the module firmly in the rack.
Power-on Inspection: Power on the VME rack, observe the diagnostic indicator lights on the front panel, and confirm that the module is in normal operating status.
Configuration and Setting: Conduct targeted configuration and programming for the VPROH2B module according to actual application scenarios and functional requirements, so as to realize customized protection and monitoring functions.
