Functional Description
IS200TDBTH4A is a contact input/relay output terminal board developed by GE. It is a part of the Mark VIe control system. The TDBT board is engineered for both DIN-rail and flat mounting, providing flexibility in installation to accommodate diverse system configurations and spatial constraints. Its compact design ensures seamless integration within control systems while facilitating ease of maintenance and accessibility. It is not designed to operate correctly with a single PDIO I/O pack, emphasizing the importance of adherence to recommended system configurations and integration guidelines.
Contact Input Capabilities
- Accepts 24 group isolated contact inputs, allowing for robust and reliable operation across various industrial applications.
- These inputs are supplied with a nominal 24, 48, or 125 V dc wetting voltage from an external source, ensuring consistent performance and compatibility with different voltage requirements.
- Noise suppression mechanisms are incorporated to safeguard against surge and high-frequency noise, enhancing signal integrity and system reliability.
Relay Output Functionality
- The terminal board features 12 form-C relay outputs, enabling efficient control and management of connected devices and processes.
- An option card can be integrated to expand relay functions, providing additional flexibility and customization options tailored to specific application needs.
Integration with PDIO I/O Packs in Mark VIe Systems
- In Mark VIe systems, the terminal board interfaces seamlessly with the PDIO (Process Digital Input/Output) I/O pack, facilitating comprehensive communication and control capabilities.
- Three connection points are provided for PDIO integration, allowing for seamless networking and communication between the terminal board and controllers over Ethernet.
- In configurations with dual controllers, each PDIO connection is strategically networked to ensure optimal communication and redundancy.
- For TMR controllers, individual network connections are established to each PDIO, ensuring redundancy and fault tolerance across the system.
Configuration
- Hardware Settings: Eliminates the need for jumpers or hardware settings, simplifying the setup process and minimizing the risk of configuration errors. This streamlined approach enhances usability and reduces installation time.
- Option Board WROBH1: For additional functionality, users can leverage the option board WROBH1, which provides enhanced capabilities for power distribution and relay control.
WROBH1 includes six jumpers that facilitate the application or removal of power from a relay, offering flexibility in configuring the board based on specific requirements.
By default, all six jumpers are installed on the board during production, ensuring that power is supplied to the relays as needed.
- Jumper Removal for Dry Contacts: In scenarios where a relay is intended for use as dry contacts and power distribution is unnecessary, users can remove the jumper from the corresponding position on the WROBH1 board. This step effectively disables the power supply to the relay, allowing it to function solely as dry contacts without any associated power distribution.
Diagnostics
- Identification Mechanism: Each connector on the terminal board I/O pack features an ID device that serves as a unique identifier. When connected, these ID devices are interrogated by the I/O processor, allowing it to retrieve essential information about the connected components.
- Content of ID Devices: The ID device contains crucial data encoded into a read-only chip. This data typically includes-
- Board serial number: A unique alphanumeric identifier assigned to the terminal board or I/O pack, facilitating traceability and asset management.
- Board type: Specifies the type or model of the terminal board or I/O pack, helping identify its intended function within the control system.
- Revision number: Indicates the version or revision of the terminal board or I/O pack, providing information about updates or modifications made to the hardware design.
- Role of WROB in ID Detection: In systems utilizing WROB (Wide Range Output Board), each PDIO (Programmable Digital Input/Output) is equipped with its own set of ID devices. These ID devices serve the same purpose as those found on terminal board I/O pack connectors, providing essential information for system compatibility checks.
- Detection of Mismatches: The I/O processor actively compares the information retrieved from the ID devices with the expected configuration of the system. If a mismatch is detected between the connected components, such as an I/O pack, terminal board, or option card, the system triggers a hardware incompatibility fault.
- Hardware Incompatibility Fault Handling: When a hardware incompatibility fault occurs, the system flags the issue as a critical error. This prompts operators or maintenance personnel to investigate and rectify the mismatched components to ensure proper system operation and compatibility.
- Ensuring System Compatibility and Reliability: By utilizing ID devices on terminal board I/O pack connectors, the system can verify the compatibility of connected components. This proactive approach helps prevent issues related to hardware mismatches, ensuring the reliability and stability of the industrial control system.
