FUNCTIONAL DESCRIPTION:

IS200TCASH1ACB is a Terminal Board manufactured and designed by General Electric as part of the Mark VIe Series used in GE Distributed Turbine Control Systems. The IS200TCAS terminal board provides the customer terminals and signal routing into the BCAA and BCAB boards. TCAS accepts bulk 28 V control power through the P5 connector. It then provides the power through connector P4 to a JGPA board in the input cable shield termination location. TCAS provides the P1 and P2 68-pin connectors for IS200TCAT terminal board cables. Internal to the module the TCAS terminal board routes signals to connectors for the BCAA and BCAB analog processing boards.

FEATURES:

• The TCAS terminal board provides the six LVDT excitation signal pairs: LVDTEXH1_R/LVDTEXL1_R through LVDTEXH6_R/LVDTEXL6_R. These excitation outputs are connected to the primary side of the LVDT position sensor.

• The primary-side signal is a 3.2 kHz sine wave excitation with a 7.07 V RMS amplitude. The LVDT secondary-side signal amplitude is proportional to the position change in the valve. The LVDT secondary-side is connected to one of the twelve TCAT terminal board LVDT input signal pairs: LVDT1H/LVDT1L through LVDT12H/LVDT12L.

• The TCAT terminal board is used to fan the LVDT signal pair to the TMR PCAA set: PCAA (R), PCAA (S), and PCAA (T) through cabling. The BCAA acquisition board provides signal conditioning to convert the RMS voltage from the secondary-side of the LVDT to a DC equivalent signal read by the processor through analog-to-digital (A/D) converters.

• PCAA Module Overview: The Core Analog (PCAA) module serves as the central hub for processing analog signals critical for the operation of a gas turbine. It supports a wide range of input and output functionalities, including thermocouple inputs, 4-20 mA current loop I/O, seismic inputs, Linear Variable Differential Transformer (LVDT) excitation and inputs, pulse rate inputs, and servo coil outputs.

• Versatility in System Configuration: The PCAA module offers versatility in system configuration, accommodating simplex, dual, and Triple Modular Redundant (TMR) systems. This flexibility allows for seamless integration into various control system architectures, catering to diverse operational requirements and ensuring compatibility with different system configurations.

• TCAT Terminal Board: The Core Analog Terminal (TCAT) board acts as an interface between the PCAA module and external sensors and actuators. It provides essential connectors and terminals for connecting thermocouple inputs, current loop I/O devices, seismic sensors, LVDTs, pulse rate sensors, and servo coil actuators, facilitating seamless signal transmission and interaction within the control system.

• Similarly, the Core Analog Shield (TCAS) terminal board complements the board by providing additional connectivity options and signal routing capabilities. It ensures efficient signal distribution and management within the control system, enhancing overall system performance and reliability.

• Comprehensive Signal Processing: Together, the PCAA module and associated TCAT and TCAS terminal boards enable comprehensive signal processing capabilities, ensuring accurate monitoring and control of critical parameters in the gas turbine operation.
