GE IS215VPROH2B｜VME Bus Turbine Protection Board｜
This module is a triple-redundant (TMR) turbine protection board, designed to operate independently of the main turbine control system. It provides high-integrity safety protection functions including emergency overspeed, emergency shutdown, and trip solenoid valve control, meeting the safety and availability requirements of critical turbine units.
Architecture and Reliability
Redundant Structure:
Triple redundancy: R8 / S8 / T8 (original X / Y / Z)
Supports online hot-plug replacement
Designed to eliminate single-point failures and maximize system availability
Core Protection Functions
Emergency Overspeed Protection (EOS)
Emergency Stop (E-Stop)
Trip solenoid valve control
Independent safety logic separate from the main control processor
I/O and Interface Configuration
Signal Inputs
Analog Inputs:
3 × analog current inputs
Typically used for pressure or flow protection
Temperature Inputs:
9 × thermocouple inputs
Used for exhaust temperature and over-temperature protection
Communication
IONet communication port
Status reporting and configuration
Maintains full independence of local trip logic
Communication failures do not inhibit protection actions
Relay Trip Control
Trip Relay Interface: TREG terminal board
Relay Configuration:
12 relays total
9 relays arranged as three groups of 2-out-of-3 (2oo3) voting
Drives three independent trip solenoid valves
Ensures:
Reliable trip execution
Prevention of false trips or failure-to-trip conditions
Power Supply
125 VDC – Trip circuit power
+5 VDC – Core logic power
Supports multi-voltage monitoring for power integrity supervision
