FUNCTIONAL DESCRIPTION:

IS230TBCIH6C is a Contact Input with a Group Isolation Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Turbine Control Systems. It is designed to handle up to 24 such inputs, making it a versatile and practical solution for a wide range of applications. The TBCI is equipped with two barrier-type terminal blocks, which provide a secure and organized way to connect the dry contact inputs. These terminal blocks ensure proper isolation and prevent any unintentional short circuits or interference between the different inputs. This configuration simplifies the installation process and ensures that the connections are stable and easy to maintain.

INSTALLATION:

• The 24 dry contact inputs are seamlessly integrated into the contact input terminal board by directly wiring them to two robust I/O terminal blocks. These terminal blocks are thoughtfully positioned on the board to ensure efficient and organized connections. To provide structural stability and ease of maintenance, the terminal blocks are securely held in place with two screws, minimizing the risk of unintended disconnections.

• The versatility of the terminal blocks becomes apparent in their design, as each block is equipped with an impressive 24 terminals. These terminals are engineered to accept wires with a gauge size of up to 12 AWG, allowing for a wide range of compatible wire thicknesses. This feature ensures compatibility with various types of wiring and provides the flexibility needed for different applications.

• For ease of maintenance and repair, the terminal blocks can be effortlessly unplugged from the contact input terminal board. This feature enables technicians or engineers to carry out any necessary maintenance tasks or troubleshoot issues conveniently. By detaching the terminal blocks, the entire system can be quickly accessed and serviced without the need for extensive disassembly, reducing downtime and increasing system uptime.

• To address any concerns regarding electromagnetic interference or grounding, a shield terminal strip is thoughtfully integrated into the design. Positioned immediately to the left of each terminal block, this shield terminal strip is connected to the chassis ground. Chassis ground serves as a reference point for grounding electrical components, reducing the risk of electrical noise and providing a reliable pathway for discharging any unwanted electromagnetic interference.

OPERATION:

• Designed to handle critical turbine control operations, the integrity of data and signal accuracy is of utmost importance. To ensure reliable performance, filters are strategically employed to effectively mitigate high-frequency noise and suppress any surge that might occur on each input near the point of signal entry.

• Given the nature of the dry contact inputs, they require a stable and secure power supply. Therefore, a floating 125 V DC supply, with a voltage range of 100 V to 145 V DC, is utilized to power these inputs. This flexible voltage range allows the system to adapt to varying power conditions, providing a robust and reliable power source for the dry contacts.

• Safety is a top priority in such applications, and to safeguard the system from potential overloads, the 125 V DC bus is thoughtfully equipped with current-limiting functionality in the power distribution module. This measure ensures that the power supplied to each contact input remains within safe operating limits, minimizing the risk of electrical faults and protecting the system components from damage.

• As the discrete input voltage signals are generated, they are sent to the I/O processor for further processing. Before these signals proceed, an essential step is to pass them through optical isolators. These isolators serve multiple crucial functions. Firstly, they provide group isolation, effectively separating the input signals from one another. This isolation prevents any cross-talk or interference between different input signals, maintaining the integrity of individual data streams.
