GE IS215VPROH1BD Emergency Turbine Protection Module with 12 Analog Output Channels 800Ω Load Driving and 4-20mA DC/0-10V DC Configurable

The GE IS215VPROH1BD is an Emergency Turbine Protection Module developed by GE as part of the Mark VI control system. This critical component works with TPRO and TREG terminal boards to form an independent emergency overspeed protection system, ensuring turbine operational safety and integrity.

• 12 configurable analog output channels (4-20mA DC/0-10V DC) with ±0.05% FS accuracy
• 800Ω load driving capacity for direct control of valve positioners, actuators, and frequency converters
• 24 digital output channels with dual-mode transistor + relay output
• Built-in triple protection against overcurrent, short circuit, and overvoltage
• Faceplate with LED indicators, power switch, and Ethernet connectors
• Independent emergency overspeed protection system for turbine safety

The VPRO board establishes a redundant emergency overspeed protection system that safeguards against critical turbine conditions. The module features a robust design with a screw-mounted faceplate containing operational interfaces and status indicators, making it essential for gas/steam turbine system reliability.
