Functional Description
IS230TDBTH6AA is a Relay Output Terminal Board developed by GE. It is a part of Mark VIe control system. The board offers signal processing and relay control. With the capability to accommodate 24 group isolated contact inputs, the board ensures seamless integration into diverse control setups. These inputs are powered by a nominal 24, 48, or 125 V DC wetting voltage, sourced externally for optimal performance.
Features
- Robust Protection Against Electrical Noise: Understanding the challenges posed by electrical noise in industrial settings, the TDBT board incorporates cutting-edge noise suppression technology. This feature shields the contact inputs from surges and high-frequency noise, ensuring reliable and accurate signal detection even in the most demanding environments.
- Versatile Relay Output Configuration: Equipped with 12 form-C relay outputs, offers unparalleled flexibility in relay control. Whether for switching, control, or monitoring applications, these relay outputs deliver consistent and precise performance. Moreover, the board welcomes expansion through the integration of an option card, allowing users to tailor relay functions to their specific requirements.
- Seamless Integration and Mounting Options: Designed for convenience and adaptability, the board supports DIN-rail and flat mounting configurations. This flexibility streamlines installation processes, enabling seamless integration into existing control panels and systems without compromising efficiency or functionality.
- Enhanced Reliability and Scalability: The board's focus on reliability and scalability empowers users to optimize their control systems for long-term success. Whether deployed in industrial automation, process control, or facility management, it delivers robust performance and adaptability to evolving operational needs.
Installation
- DIN Rail Mounting: The TDBT board, along with a plastic insulator, mounts securely on a sheet metal carrier, which in turn attaches to a DIN rail. This method offers a standardized and space-saving solution, ideal for control panels and enclosures.
- Cabinet Mounting: Alternatively, the board, combined with the insulator, can mount on a sheet metal assembly, which then bolts securely within a cabinet. This option provides flexibility for installations where DIN rail mounting is not feasible or preferred.
- Terminal Blocks: Two sets of 48 terminal blocks are provided for wiring connections. These terminal blocks typically accommodate 18 AWG wires, ensuring secure and reliable connections. TB1 and TB2 connections
- TB1 (Upper Set): Connects to the relay portion of the board, facilitating relay control and monitoring functions.
- TB2 (Lower Set): Connects to the contact input circuits, enabling the detection and processing of external signals.
- Consistent Screw Assignments: The screw assignments for both sets of terminals (TB1 and TB2) are identical to those found on the SRLY relay board and the STCI contact input terminal board. This standardization ensures compatibility and ease of installation across different board types.
- Separate Bracket: Shields, if present, should be terminated on a separate bracket. This practice minimizes interference and ensures proper grounding, maintaining signal integrity and system reliability.
Diagnostics
- The I/O processor monitors the following functions on the TDBT: Contact Wetting Voltage: The processor monitors the contact wetting voltage. If this voltage drops below 40% of the nominal level, a diagnostic alarm (fault) is triggered and latched.
- Relay State Feedback: Provides diagnostic feedback to the PDIO, indicating each relay’s state by monitoring an isolated set of contacts on each relay. This position feedback is distributed to all three PDIO packs.
- Fuse Status Detection: When WROB is connected with TDBT, isolated voltage feedback detects the status of the six fuse pairs on the board. It then relays this fuse status feedback to all three PDIO packs.
- Connector ID Verification: Each terminal board I/O pack connector contains an ID device, interrogated by the I/O processor. This ID device is a read-only chip coded with the board serial number, board type, and revision number. WROB includes three ID devices, one per PDIO. If there is a mismatch between the I/O pack, terminal board, or option card, a hardware incompatibility fault is generated.
