Functional Description

IS230TBCIH2C is an Simplex Contact Input Board developed by GE. It is a part of Mark VI control system. The terminal board operates with a nominal 125 V dc excitation voltage, which is floating and can range from 100 to 145 V dc. This wide excitation voltage range allows for compatibility with various power sources and simplifies installation and integration with different control systems. For applications requiring 125 V dc, the first 21 circuits draw 2.5 mA each, while the last three circuits draw 10 mA each. This current distribution ensures that the terminal board effectively manages power consumption while maintaining precise and stable contact input readings. The TBCI terminal board works seamlessly with VTCC or VCRC and supports both simplex and TMR (Triple Modular Redundancy) applications. This adaptability makes the TBCI suitable for various control system configurations, providing options for redundancy and fault tolerance.

Installation

Connecting the Contact Input with Group Isolation terminal board to the contact excitation voltage source and the I/O processors is a straightforward process, providing flexible options for simplex and TMR (Triple Modular Redundancy) systems. The terminal board allows seamless integration into various Mark VI or Mark VIe control systems, offering redundancy options based on the specific system requirements.

  • Connecting to Contact Excitation Voltage Source: To connect to the contact excitation voltage source, the user can utilize plugs JE1 and JE2. These plugs serve as the interface between the terminal board and the voltage source. By securely plugging JE1 and JE2 into their designated connectors on the terminal board, the contact excitation voltage is supplied , allowing it to excite and monitor the dry contact inputs.
  • Simplex System Connection: In a simplex system configuration, the component is directly connected to the I/O processor using connector JR1. The cable or I/O pack required for the specific Mark VI or Mark VIe system is appropriately plugged into JR1 on both the terminal board and the I/O processor. This establishes a single, non-redundant communication path between the TBCI and the control system, suitable for applications that do not require additional redundancy.
  • TMR System Connection: For a TMR system configuration, the board requires a higher level of redundancy to ensure fault tolerance and reliability. It is connected to three I/O processors using connectors JR1, JS1, and JT1. The appropriate cables or I/O packs are plugged into these connectors on the terminal board and the respective I/O processors. This configuration provides three independent communication paths between the control system, allowing for simultaneous monitoring and voting of the contact input signals.
  • Adaptability to Mark VI and Mark VIe Systems: The terminal board is designed to be compatible with both Mark VI and Mark VIe control systems. Depending on the system type and the desired level of redundancy, the user can choose to use cables or I/O packs to establish the connections accordingly. This adaptability allows for seamless integration into various control system configurations, ensuring optimal performance and reliability.

Frequently Asked Questions

 

What is IS230TBCIH2C?
It is an Simplex Contact Input Board developed by GE

What is the capacity of each terminal block on the terminal board?
Each terminal block is equipped with 24 terminals that can accept up to 12 AWG wires. This generous capacity makes the terminal board suitable for managing a considerable number of contact inputs in a compact space.

How does the shield terminal strip contribute to the reliability of the contact inputs?
Adjacent to each terminal block, a shield terminal strip is thoughtfully attached to chassis ground. This strip serves as a dedicated grounding point, effectively grounding and shielding the contact inputs. By protecting against electromagnetic interference and noise, the shield terminal strip ensures signal integrity and reliable performance of the contact inputs.

How does the left-side location of the shield terminal strip enhance convenience?
The proximity of the shield terminal strip to the left of each terminal block enhances wiring convenience and organization. With the grounding points immediately adjacent to the terminal blocks, the length of grounding wires is minimized. This reduces the possibility of ground loops and further improves the reliability of the contact inputs.
