GE IS215VPWRH2AC VME Protection Assembly for Mark VI Turbine Control

The GE IS215VPWRH2AC is an Emergency Turbine Protection Card in the Mark VI Speedtronic system, a key upgrade from the Mark V with added wind turbine support. As part of GE's legacy Speedtronic line, it provides independent emergency overspeed protection, working with TPRO and TREG terminal boards to control trip solenoids separately from the main turbine control system.

A lower-power variant supporting one TREG board (vs. VPROH1 for two TREGs), it features a front faceplate with essential ports: power plug, Ethernet ID, IONet, parallel port, D-shell connectors, and status LEDs. Its rear houses two stacked boards with components like backplanes, capacitors, integrated circuits, heat sinks, and vertical connectors, secured via standoffs. Part of a triple-redundant setup, it ensures turbine safety in gas, steam, and wind applications.

• Emergency Protection: Delivers independent overspeed protection via TPRO/TREG terminal boards, controlling trip solenoids to trigger turbine trips when needed.
• Mark VI Integration: Supports the series' expanded applications with a conformal-coated PCB for durability.
• Limited TREG Support: Designed for single TREG board setups; use VPROH1 for dual TREG requirements.
• Diagnostic & Connectivity: Front LEDs indicate status; ports enable monitoring and configuration.
• Redundant Design: Part of a triple-modular system, allowing reliable operation even during maintenance or faults.
