GE IS215VPROH1B overspeed protection module

Basic Product Information
Project Information
Brand General Electric/GE
Model IS215VPROH1B
Alias/Abbreviation VPRO (referred to as such in most manuals and documents)
Mark VI/Speedtronic series
Product type: Emergency turbine protection module/overspeed protection module
Origin: United States
Weight 5 pounds (approximately 2.27kg)
Main functions

Function Description
Emergency overspeed protection: When the speed exceeds the set value, it quickly triggers the emergency trip function to protect the turbine from damage
The emergency trip function provides an independent emergency trip function, which drives the trip solenoid valve by controlling the relay
The emergency stop function has an emergency stop function and supports manual and automatic testing
Speed difference detection detects speed differences for system monitoring and protection
Backup synchronization check protection provides synchronization check protection function, powered by two single-phase voltage transformers
Fault detection can detect sensor faults and connection issues
Redundant architecture
Characteristic Description
The triple redundant design system consists of three completely independent redundant VPRO boards (referred to as R8, S8, T8)
Each VPRO board has independent I/O interfaces, processors, power supplies, and Ethernet communication capabilities for independent operation
The voting mechanism controls 12 relays on TREG, of which 9 form three groups to control three shutdown solenoid valves
TREG board connection controls the trip solenoid valve through TREG board, TREG provides positive pole (125V DC), TRPG provides negative pole
The extension interface can drive the second TREG board through the J4 interface
