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

  • Designed with meticulous attention to detail, allowing it to handle these critical tasks effectively. One notable feature is its ability to accommodate a maximum of two #12 AWG wires per point, with each wire insulated for 300 volts. This capacity for handling substantial wire sizes and voltage levels is essential in ensuring the integrity and safety of the connections. It provides the necessary electrical pathways to convey temperature data from thermocouples to the control system.
  • In the context of TMR systems, redundancy and fault tolerance are paramount. The component is engineered to meet these requirements, contributing to the high reliability and availability demanded by industries such as power generation, oil and gas, and more. Its compatibility with the VTCC board and its capability to fan out inputs to the R, S, and T racks ensure that temperature data is redundantly processed and monitored, minimizing the risk of system failures and ensuring seamless operations even in the event of component failures.

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

  • 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.
