Product Overview
The GE IS200TPROH1BBB is a protective termination board designed for the Mark VI series, a family used to automate and manage industrial gas and steam turbines. This board serves as a critical element in the emergency overspeed and synchronization protection system, delivering essential signals such as speed, temperature, generator voltage, and bus voltage to the VPRO boards. By collaborating with the VPRO, the IS200TPROH1BBB ensures safety and stability in turbine operations, providing prompt and coordinated responses to emergency situations.
Manufactured by General Electric in the United States, this protection board is built to withstand demanding industrial environments. Its compact design measures 17.8 cm high by 33.02 cm wide, making it suitable for installation in standard control panels.

The operating temperature range of -30 to 65 °C ensures reliable performance in extreme conditions, while the board's dimensions facilitate straightforward integration into existing control cabinets. The IS200TPROH1BBB is part of the Mark VI series, known for its robust design and advanced protection capabilities.
System Configuration and Integration
In a typical Mark VI system, the IS200TPROH1BBB works with triple redundant VPRO boards that operate independently from the primary turbine control system. These VPRO boards manage trip solenoids via TREx modules (TREG, TREL, or TRES), providing critical control over emergency trip functions. The TPRO board serves as the source of inputs to all three VPRO boards, ensuring coordinated signal delivery for emergency operations.
The cabling configuration from TPRO to VPRO and TREx terminal boards is designed to maintain data flow and control signals between these vital modules. This layout is crucial for the reliability of the emergency protection system.
Functional Roles in Emergency Protection
The IS200TPROH1BBB plays a pivotal role in emergency overspeed protection and emergency stop functions. VPRO, which receives inputs from TPRO, controls up to three trip solenoids connected between TREx and TRPx terminal boards. TREx and TRPx boards manage the positive and negative sides of the 125 V DC supply to trip solenoids, allowing either board to trip the turbine in an emergency.
Additionally, VPRO controls 12 relays on the TREG board, with nine forming three groups to vote inputs that manage the three trip solenoids. A secondary TREG board can be driven from VPRO through J4, enhancing redundancy and control capabilities.
Physical Characteristics and Build Quality
The IS200TPROH1BBB is a long, rectangular PCB populated with a variety of electronic components. Two large terminal blocks on the left edge feature silver terminals numbered 1 to 48. At the top, a pair of red relays with yellow parts sit beside metal oxide varistors. Three black potentiometers are grouped near the upper right corner, and several yellow capacitors and diodes are distributed across the board. This robust construction ensures durability in demanding industrial environments.
Applications
This protection board is ideal for use in power generation plants, oil and gas facilities, and any industrial process that relies on steam or gas turbines. The IS200TPROH1BBB ensures that turbine operations remain safe and stable, particularly in emergency scenarios where rapid response is critical.
Installation and Setup
When installing the IS200TPROH1BBB, ensure that the board is securely mounted in a suitable enclosure, following the manufacturer's guidelines for wiring and connections. Verify that all terminal connections are properly torqued and that the board is oriented correctly to avoid interference with other components. Always refer to the system documentation for specific installation requirements.
Maintenance and Reliability
Regular inspection of the IS200TPROH1BBB is recommended to ensure optimal performance. Check for signs of wear, corrosion, or loose connections. The board's operating temperature range of -30 to 65 °C allows it to function reliably in harsh environments, reducing the risk of unexpected failures. By maintaining the board properly, you can extend its service life and minimize downtime.
