Functional Description

IS200TBCIS3C is a Contact Input with a Group Isolation Terminal Board developed by General Electrics. It is designed to handle operational tasks, it effectively accommodates up to twenty-four dry contact inputs, which are connected through two barrier-type terminal blocks. This model demonstrates versatility in its applicability, catering to a range of control systems.

Compatibility and Flexibility

  • The model exhibits compatibility with various board types.
  • It seamlessly integrates with Mark VIe models like IS220PDIA and Mark VIeS models like YDIA, along with their corresponding PDIA and YDIA units.
  • This adaptability empowers users with diverse configuration options to suit their specific system requirements.

Operational Configuration

  • Operating within both Simplex and Triple Modular Redundant (TMR) systems, the module utilizes JS1, JT1, and JR1 connectors to connect to I/O processors in TMR setups.
  • For Simplex systems, the connection is established solely through the JR1 connector.
  • In Mark VIe/VIeS systems, associated I/O packs plug directly into the TBCI model, attaching securely to side-mounting brackets. Proper operation of the model necessitates downloading the appropriate firmware.

Cabling Connections

Simplex System with Connector JR1

In a simplex system configuration, a single connector JR1 is employed. This connector serves as the interface for connecting cables or I/O packs to the Mark VI or Mark VIe system. The specific type and number of cables or I/O packs depend on the system's requirements and the application.

TMR (Triple Modular Redundancy) System

In contrast to the simplex setup, a TMR system utilizes all three connectors available. This redundancy scheme is employed to enhance system reliability by providing backup components. In such a configuration, all three connectors are used to connect various cables and I/O packs.

Cables and I/O Packs

Cables and I/O packs are essential components of the system, and their usage depends on the specific Mark VI or Mark VIe system and the chosen level of redundancy. These components facilitate the transfer of data and signals within the system, ensuring proper functionality and communication.

Mark VIe System Configuration

For a Mark VIe system, the I/O packs are connected to a specific component called the TBCI (Terminal Base Connector Interface). These packs are attached to side-mounting brackets, providing a secure and organized installation. One or two Ethernet cables are typically plugged into the I/O pack to establish network connectivity. In some cases, firmware updates or downloads may be necessary to ensure the I/O pack's compatibility and functionality within the system.

Wiring and Maintenance

  • Wiring the product involves connecting the twenty-four dry contact inputs directly to the designated I/O terminal blocks on the terminal board.
  • These I/O blocks are held securely by two screws and can be easily unplugged from the board for maintenance. Each terminal block features twenty-four terminals, capable of accommodating 12 AWG wires. Adjacent to each terminal block, a shield terminal strip connected to chassis ground ensures effective grounding.

Diagnostic Tests and Fault Detection

  • Several diagnostic tests are available for the model. One crucial test monitors the excitation voltage on the TBIC model.
  • If the excitation voltage drops below 40 percent of the nominal value, an I/O pack will set and latch a diagnostic alarm. Additionally, a fault is generated if the input from the board does not match the TMR voted value derived from all three associated boards.

Product Attributes

  • Centralized Connection Point: Streamline your wiring setup with a centralized location for terminating multiple wires or cables. Say goodbye to scattered connections and welcome a neat and organized control panel.
  • Group Isolation for Safety: Safety is our top priority. Our terminal board ensures clear isolation between different groups of connections, preventing any cross-talk or interference that could lead to hazardous situations.
  • Clearly Labeled Terminals: Each terminal is thoughtfully labeled, making identification and management of connections a breeze. No more confusion or guesswork during installation or maintenance.
  • Versatile Mounting Options: Whether you need wall-mounting, panel-mounting, or enclosure-mounting, our terminal board offers flexible installation options to adapt to your specific installation needs.
  • Efficient Wire Management: Keep your wiring neat and organized, reducing the chances of errors or malfunctions caused by tangled wires.

What is IS200TBCIS3C?
It is a Contact Input with a Group Isolation Terminal Board developed by General Electrics.

What is the significance of the coded information in the read-only chip?
The coded information in the read-only chip includes crucial details like the board's serial number, type, revision number, and the specific JR1/JS1/JT1 connector location. This information is used to validate the board's compatibility and ensure proper functioning within the system.

What happens if a mismatch is detected during the chip reading process?
If a mismatch is identified between the information read from the chip and the expected parameters, a hardware incompatibility fault is triggered. This fault alerts users to a potential mismatch between the connector and the connected board, ensuring that incompatible components are not used together.

How does the hardware incompatibility fault benefit system operations?
The hardware incompatibility fault plays a crucial role in maintaining system integrity. It prevents the use of components that are not properly matched or configured, reducing the risk of errors, malfunctions, or data inaccuracies within the system.
