FUNCTIONAL DESCRIPTION
IS200TBTCS1B is a Thermocouple Input Terminal Board manufactured by General Electric. It is a part of Mark VIeS Series used in GE Speedtronic Gas Turbine Control Systems. Its primary function involves interfacing with a VTCC (Vital Turbine Control Cabinet) board, efficiently distributing and managing thermocouple inputs to the VTCC R, S, and T racks. This integration is pivotal in ensuring the accurate and reliable operation of vital turbine control processes.
Product Attributes
- The system is designed to perform a critical role within turbine control architectures, particularly by interfacing with the VTCC (Vital Turbine Control Cabinet) board. Its primary function is to efficiently distribute and manage thermocouple inputs across the VTCC’s R, S, and T racks. This structured integration ensures that temperature data from various turbine components is accurately routed to the control system for real-time monitoring and analysis. Such reliable data acquisition is essential for maintaining optimal turbine performance and safeguarding the system against overheating or other thermal anomalies.
- One of the key attributes of this component is its robust electrical design. Each connection point is capable of accommodating up to two #12 AWG wires, each insulated for up to 300 volts. This capacity to handle relatively large wire sizes and high insulation ratings reinforces the integrity of the wiring and ensures safe, stable electrical connections under demanding operating conditions. These electrical pathways form the backbone for transmitting temperature signals from field sensors to the control modules housed within the VTCC.
- In Triple Modular Redundant (TMR) systems, such as those employed in critical infrastructure like power generation, oil and gas, and industrial automation, the need for fault tolerance and redundancy is paramount. This system component is meticulously engineered to support such high-reliability environments. Its compatibility with the VTCC board and ability to fan out thermocouple signals to the R, S, and T racks enables redundant signal processing. This design approach ensures that even if one path or rack encounters a failure, the remaining modules continue to receive and process accurate data, thereby maintaining uninterrupted turbine control. This level of operational resilience is crucial in industries where downtime or errors could lead to significant financial and safety consequences.
- Overall, the system not only strengthens the accuracy and dependability of turbine temperature monitoring but also plays an indispensable role in enabling redundant, high-integrity control across mission-critical applications.
Features
- Positioned along the left edge of the board are two substantial, solid black terminal blocks, denoted as TB1 and TB2, each housing twenty-four silver metal cube-shaped terminals.
- Along the right border, two jack connector ports, JA1 and JB1, offer additional connectivity options for attaching external components or boards. In the middle of the board, two groups of small components are present, each featuring five vertical rows. On the left side are blue and white resistors, while adjacent to them are small silver capacitors. These two rows of resistors and capacitors repeat on the right side, with an additional row of components identified by the letter 'L' situated on the right.
Installation Procedure
- The two I/O terminal blocks should receive the thermocouple wires directly.
- Two screws are used to secure these detachable blocks to the terminal board where they are placed. Each block has 24 terminals that can accommodate wires up to 12 AWG.
- Each terminal block has a shield terminal strip that is connected to the chassis ground. In Mark VI systems, cable the TBTC J-type connectors to the I/O processors in the VME rack.
Operation
- There are two grounding options for the 24 thermocouple inputs. The distance they can be from the turbine control panel is up to 300 m (984 ft), and the maximum two-way cable resistance is 450.
- TBTC includes two CJ reference devices and high-frequency noise reduction. For each type of thermocouple, the analog-to-digital conversion and linearization are carried out by the I/O processor. One VTCC is utilized in systems. Two PTCC packs plug into TBTC in Mark VIe simplex systems to obtain 24 thermocouple inputs.
