Functional Description

IS200TBCIH1BBD is a Contact Input Terminal Board developed by GE. It is a part of Mark VI control system. The contact input terminal board (TBCI) serves as an interface within the system, facilitating the integration of 24 dry contact inputs essential for monitoring various operational parameters.

Features

• Input Connectivity: Designed to accommodate 24 dry contact inputs, which are typically wired to two barrier-type terminal blocks. These terminal blocks provide a secure and organized means of connecting the input signals, ensuring reliable communication between the external devices and the system.
• Power Supply Arrangement: To enable the excitation of the contact inputs, DC power is supplied. This power supply arrangement ensures that the contact inputs receive the necessary energy to operate effectively, facilitating the detection and transmission of relevant signals to the system.
• Noise Suppression Circuitry: To enhance the reliability and accuracy of signal detection, the contact inputs are equipped with noise suppression circuitry. This circuitry serves to protect against potential disturbances such as surges and high-frequency noise, which could otherwise interfere with the proper functioning of the input signals. By filtering out unwanted noise, it helps maintain signal integrity and minimize false readings or errors.
• Surge Protection: Surge protection mechanisms incorporated safeguard against transient voltage spikes that may occur due to external factors such as lightning strikes or power fluctuations. These protective measures help prevent damage to the contact inputs and ensure the continued operation of the system even in challenging environmental conditions.
• High-Frequency Noise Filtering: High-frequency noise filtering capabilities within the TBCI help mitigate the effects of electromagnetic interference (EMI) and radio frequency interference (RFI) on the contact inputs. By suppressing these unwanted signals, the TBCI maintains signal clarity and reliability, enabling accurate monitoring and control of the connected devices.
• Reliability and Safety: By incorporating noise suppression circuitry and surge protection mechanisms, the TBCI enhances the overall reliability and safety of the system. This ensures consistent performance and minimizes the risk of signal distortion or equipment damage, contributing to the longevity and effectiveness of the system's operation.

Wiring

• Direct Wiring to I/O Terminal Blocks: The 24 dry contact inputs are directly wired to two I/O terminal blocks mounted. These terminal blocks serve as the primary interface for connecting the external devices to the system. The inputs are distributed evenly across the terminal blocks to facilitate organized wiring and identification.
• Mounting and Accessibility: The terminal blocks are securely held in place using two screws, ensuring stability during operation. Additionally, the terminal blocks are designed to be easily unplugged from the board for maintenance purposes. This feature simplifies troubleshooting and replacement of components, minimizing downtime and enhancing serviceability.
• Wire Acceptance and Capacity: Each terminal block is equipped with 24 terminals, providing ample connectivity options for the input signals. These terminals are capable of accepting wires of up to 12 AWG gauge, accommodating a wide range of wire sizes commonly used in industrial applications. This versatility allows for flexibility in wiring configurations and ensures compatibility with various types of input devices.
• Shield Terminal Strip for Grounding: Adjacent to each terminal block, a shield terminal strip is located, attached to chassis ground. This strip serves as a convenient point for grounding purposes, providing a dedicated connection for shielding against electromagnetic interference (EMI) and ensuring proper grounding of the input signals. Grounding the system helps maintain signal integrity and reduces the risk of noise-induced errors

Cabling Connections

• Connector Usage for Simplex and TMR Systems: In a simplex system configuration, connector JR1 is utilized for establishing the necessary cabling connections between the TBCI and the corresponding components within the system. For a Triple Modular Redundancy (TMR) system setup, all three connectors (JR1, JS1, and JT1) are utilized to accommodate the redundancy requirements of the system. This comprehensive connection scheme ensures redundancy and fault tolerance, enhancing the reliability of the overall system.
• Selection of Cables or I/O Packs: The selection of cables or I/O packs for connection depends on the specific type of Mark VI or Mark VIe system being used, as well as the desired level of redundancy. Depending on the system requirements and configuration, cables or I/O packs are chosen to establish the necessary communication pathways between the TBCI and other system components. These cables or I/O packs facilitate the transmission of signals and data essential for monitoring and control purposes.
• Compatibility and Redundancy Considerations: The cabling connections are designed to ensure compatibility with both Mark VI and Mark VIe systems, offering versatility to accommodate different system architectures and configurations. The level of redundancy required for the system influences the choice of connectors and the number of cables or I/O packs utilized. By utilizing multiple connectors in a TMR system, redundancy is achieved, enhancing system reliability and fault tolerance.
• Installation and Configuration Flexibility: The modular nature of the cabling connections allows for easy installation and configuration adjustments to meet specific system requirements. Whether deploying a simplex or TMR system, the flexibility in cabling connections enables seamless integration and scalability, allowing for future expansion or modifications as needed.
• System Optimization and Performance: By facilitating the appropriate cabling connections based on system type and redundancy level, it contributes to the optimization of system performance and reliability. The careful selection and configuration of cabling connections ensure efficient data transmission, minimal signal loss, and robust connectivity, enhancing the overall functionality and effectiveness of the system.
