GE IS215VPROH1BD VME Protection Assembly for Mark VI Turbine Control

The GE IS215VPROH1BD is a Turbine Protection Board, a core component in GE's Mark VI system, forming an independent emergency overspeed protection system alongside TPRO and TREG terminal boards.

• Triple Redundancy: Three independent boards with separate processors, power supplies, and I/O, allowing hot-swapping without compromising protection.
• Overspeed Protection: Uses three dedicated magnetic speed pickups per board to detect EOS, with configurable trip limits and verification via I/O configurator.
• Trip Solenoid Control: Manages up to three triple-redundant trip solenoids via TREG's 12 relays, ensuring reliable emergency shutdown.
• Diagnostics: Front-panel LEDs and comprehensive fault monitoring for relays, solenoids, and inputs.
• Connectivity: Ethernet for controller communication, VME interface for programming, and latching connectors for TPRO/TREG links; J7 supplies 125V DC power.
• Versatile Inputs: Supports three analog current inputs, nine thermocouple inputs, and backup synch check with 115V PT inputs.
• Safety Integration: Functions independently from the main control system, enhancing reliability in critical turbine protection scenarios.
