IS230TTURH2C is a Primary Turbine Protection Assembly Input Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Control Systems. The Primary Turbine Protection Assembly Input Terminal Board is a component used in various industries, particularly in power generation and turbines. Its purpose is to provide a connection point for various input signals and sensors that are critical for monitoring and protecting the turbine during operation. The Input Terminal Board typically includes terminals or connectors where different sensors and instruments can be attached. These sensors may include temperature sensors, pressure transducers, flow meters, vibration sensors, and other devices that provide essential data about the turbine's condition and performance.
Component Connections: Connect the wires for the magnetic pick-ups, shaft pick-ups, potential transformers, and breaker relays to the two I/O terminal blocks: TB1 and TB2. The terminal blocks are securely held down with two screws each and have 24 terminals that can accept wires up to #12 AWG in size. Ensure that the connections are made according to the specified wiring diagram, which can be found in the figure labeled "TTUR Terminal Board Wiring."
Shield Termination: Adjacent to each terminal block, you will find a shield termination strip attached to the chassis ground. This strip provides a grounding point for shielded cables. It is essential to properly terminate the shields of the connected cables at these shield termination strips. This helps minimize electromagnetic interference (EMI) and ensures accurate signal transmission.
Relay Driver Configuration: Use jumpers JP1 and JP2 to select the desired configuration for the relay drivers K25 and K25P. These jumpers enable you to choose between SMX (Simplex) or TMR (Triple Modular Redundant) operation. Carefully set the jumpers according to the system requirements and configuration specifications.
Optional TTL Active Speed Pick-ups: If you are using optional TTL active speed pick-ups, connect their wires to TB3. These pick-ups require an external power supply to operate correctly. Ensure that the power supply is appropriately connected and meets the specified requirements.
Cable Connectors: In a simplex system, use cable connectors JR5 and JR1 for the required signal connections. If you are setting up a TMR system, all six cable connectors (JR5, JR1, JS5, JT5, JS1, and JT1) need to be utilized. Follow the designated wiring configuration and ensure secure connections between the TTUR module and the corresponding cables.

What relays are present in the module, and what is their role?
It incorporates three relays- K25, K25P, and K25A. All three relays must close simultaneously to provide 125 V DC power to close the main breaker, known as 52G. This power is crucial for the proper operation and control of the breaker.
Which connectors are used for specific signal connections?
It utilizes different connectors for different signal connections. The speed signal cable to the VTUR boards is connected using the JR5 connector. Other signals, excluding the speed signal, are connected using the JR1 connector.
How are signals distributed in TMR systems within the module?
In TMR systems, the signals fan out to multiple connectors to achieve redundancy and enhance system reliability. The signal distribution involves the JR5, JS5, JT5, JR1, JS1, and JT1 connectors. Each connector receives specific signals, ensuring redundant pathways for signal transmission.
