Functional Description
IS230TBCIH1C is a contact input assembly developed by GE. It is a part of Mark VI control system. The Contact Input with Group Isolation (TBCI) terminal board is a versatile and efficient solution for handling dry contact inputs in various control systems. With support for 24 contact inputs, the TBCI allows for the monitoring and integration of multiple external devices or signals. The dry contact inputs are wired to two barrier-type terminal blocks, ensuring secure and reliable connections. These terminal blocks are designed to handle the contact inputs efficiently and provide a robust connection platform. The contact inputs' noise suppression circuitry offers protection against electrical surges and high-frequency noise, ensuring reliable and accurate signal processing even in challenging industrial environments.
Installation
- Connecting the wires for the 24 dry contact inputs on the Contact Input with Group Isolation (TBCI) terminal board is a straightforward and secure process. The terminal board is designed for user-friendly installation and maintenance, providing convenience and reliability in managing contact inputs.
- Wiring the Dry Contact Inputs: The 24 wires corresponding to the dry contact inputs are connected directly to two I/O terminal blocks mounted on the terminal board. These terminal blocks are specifically designed to handle the contact input wiring efficiently. The user can easily insert the wires into the designated terminals of the blocks.
- Securing the Terminal Blocks: To ensure stable connections and reliability, each terminal block is held down with two screws. These screws firmly secure the terminal blocks to the terminal board, preventing any accidental disconnection of the wires during operation. This robust design guarantees that the contact input wiring remains intact and reliable, even in challenging industrial environments.
- Maintenance Convenience: For maintenance purposes, the terminal blocks can be easily unplugged from the board. This feature allows technicians and engineers to disconnect and access the contact input wires without the need to remove the entire terminal board. During maintenance, users can quickly inspect, troubleshoot, or replace specific contact inputs as needed.
- Terminal Block Capacity: Each terminal block is equipped with 24 terminals that can accept up to #12 AWG wires. This generous capacity accommodates multiple wires, making it suitable for managing a considerable number of contact inputs in a compact space.
- Shield Terminal Strip for Grounding: Adjacent to each terminal block, a shield terminal strip is thoughtfully located and attached to chassis ground. This strip is essential for grounding and shielding the contact inputs. By providing a dedicated grounding point, the terminal board effectively protects the contact inputs from electromagnetic interference and noise, ensuring signal integrity and reliable performance.
- Left Side Location for Easy Access: The proximity of the shield terminal strip to the left of each terminal block enhances wiring convenience and organization. With the grounding points immediately to the left of the terminal blocks, the length of grounding wires is minimized, reducing the possibility of ground loops and further improving the reliability of the contact inputs.
Wiring
- The 24 dry contact inputs are directly wired to two I/O terminal blocks mounted on the board. These terminal blocks are securely fastened to the board with two screws each, providing stability and durability in high-vibration environments typical of industrial settings. Each terminal block is equipped with 24 terminals, capable of accepting wires up to 12 AWG in size. This capacity allows for flexibility in wiring configurations and accommodates a wide range of wire gauges commonly used in electrical installations.
- One of the key features of the terminal blocks is their ease of maintenance. They are designed to be easily unplugged from the terminal board, facilitating quick access for inspection, testing, repair, or replacement of wiring connections. This accessibility minimizes downtime during maintenance activities, ensuring continuous operation of the connected equipment and systems.
- Adjacent to each terminal block, a shield terminal strip is mounted and connected to chassis ground. This shield terminal strip serves a crucial role in maintaining proper grounding for the shielded cables connected to the terminal blocks. Grounding the shields helps mitigate electromagnetic interference (EMI) and ensures reliable signal transmission in sensitive electronic circuits. By providing a dedicated grounding point, the shield terminal strip enhances the overall electrical integrity and performance of the wiring configuration.
- During installation, attention to proper grounding practices is essential. Ensuring that the shield terminal strips are securely connected to the chassis ground establishes a reliable ground path for the entire system. This grounding not only enhances safety but also contributes to the operational reliability of the equipment by reducing the risk of electrical noise and interference.
