Functional Capabilities
Turbine Speed Measurement
The IS200TTURH1BEC incorporates 12 passive pulse rate devices that sense the toothed wheel of the turbine, providing accurate rotational speed measurement. These devices generate electrical pulses in response to the passage of teeth, feeding essential data into the control system for effective monitoring.
Voltage Monitoring
The board monitors generator voltage and bus voltage signals obtained through potential transformers. This constant oversight enables real-time analysis, triggering alerts or corrective actions when deviations occur, thereby maintaining operational stability.
Relay Outputs for Breaker Control
Featuring three relays (K25, K25P, and K25A), the IS200TTURH1BEC supplies 125 V DC power necessary to close the main breaker 52G. This output is essential for automatic generator synchronization.
Industry Applications
Primarily used in turbine control systems, the IS200TTURH1BEC is ideal for power generation plants and industrial facilities relying on GE Mark VI systems. Its ability to handle both simplex and TMR configurations makes it versatile for various turbine I/O setups, ensuring redundancy and failover capabilities.
Installation & Setup Guidance
During installation, ensure all components—magnetic pickups, potential transformers, and breaker relays—are correctly wired to terminal blocks TB1 and TB2. Each block accepts wires up to 12 AWG and includes a shield termination strip for grounding. Jumpers JP1 and JP2 select between SMX and TMR relay driver options. For TMR systems, use all six cable connectors (JR5, JS5, JT5, JR1, JS1, JT1) for signal distribution.
Maintenance & Reliability
Routine inspection of connectors and terminal blocks is recommended to prevent loose connections. The board operates within a temperature range of -30 to 65°C, so ensure proper ventilation and avoid exceeding these limits. Surface-mount technology enhances durability, reducing maintenance frequency.
Compatibility & Integration
The IS200TTURH1BEC is designed for GE Mark VI systems and works with PTUR and VTUR boards. It supports both simplex and TMR configurations, with voting logic selected via jumpers. This flexibility allows integration into diverse turbine control architectures.
Selection Guide & Purchasing Advice
Before purchasing, verify your system configuration (simplex or TMR) and confirm the board revision compatibility. The IS200TTURH1BEC is available in stock at PLC Source PRO, ensuring quick delivery for your maintenance or upgrade needs.
