Functional Description
IS200TRTDH1A is an RTD terminal board developed by GE. It is part of the Mark VI series. The Resistance Temperature Device terminal board serves as an interface for accommodating 16 three-wire RTD inputs, each wired to two barrier-type terminal blocks. These inputs are crucial for temperature measurement and control within the system.
Input Configuration and Wiring
- The 16 RTD inputs are intricately wired to ensure optimal functionality and accuracy.
- The utilization of two barrier-type terminal blocks provides a structured and organized approach for connecting these inputs, enabling efficient management and maintenance.
Noise Suppression Circuitry
- To safeguard against potential disturbances, such as surges and high-frequency noise, the RTD inputs incorporate specialized noise suppression circuitry.
- This circuitry acts as a protective measure, ensuring the stability and reliability of temperature readings by mitigating external interference.
Communication with I/O Processors
- The TRTD terminal board engages in communication with one or more I/O processors within the system. These I/O processors undertake the vital task of converting the analog RTD input signals into digital temperature values. Subsequently, these digital temperature values are transmitted to the controller for further processing and monitoring.
- The seamless communication between the TRTD terminal board and the I/O processors streamlines the process of temperature data acquisition and ensures the accurate transmission of temperature values to the controller. This integration forms a fundamental part of the system's temperature measurement and control functionality, contributing significantly to its overall efficiency and reliability.
Installation
- Each RTD is connected to the terminal blocks, ensuring a direct and reliable connection for accurate temperature measurement. These terminal blocks are firmly secured in place using two screws each, providing stability and durability to the wiring setup.
- The terminal blocks feature 24 terminals, capable of accommodating wires up to 12 American Wire Gauge (AWG) in size. This generous capacity allows for versatile wiring options and supports a range of wire sizes to cater to specific installation needs.
- Adjacent to each terminal block, a shield terminal strip is positioned and connected to the chassis ground. This strip serves as a grounding point, enhancing system stability and mitigating potential electrical interference or noise that could affect the accuracy of the RTD readings.
- The layout design ensures an organized and structured wiring arrangement, facilitating ease of installation and future maintenance. The use of terminal blocks with multiple terminals allows for neat and orderly wiring, minimizing the risk of cross-connections or disorganized wiring that could lead to operational issues.
- The meticulous installation of the RTDs onto the terminal board, coupled with the secure mounting of terminal blocks and the inclusion of shield terminal strips for grounding, contributes to a robust and reliable system setup. This installation process emphasizes both precision and stability in wiring connections, ensuring accurate temperature measurement and system integrity.

Frequently Asked Questions
What is IS200TRTDH1A?
It is an RTD terminal board developed by GE under the Mark VI series.
What measures are taken if an RTD is determined to be out of hardware limits?
To prevent any adverse effects on other input channels, an RTD identified as out of hardware limits is immediately removed from the scanned inputs. This proactive step ensures the integrity and accuracy of the remaining input channels.
How are repaired channels reinstated into the system after being removed?
Repaired channels are automatically reinstated into the system after a period of 20 seconds. Additionally, there is an option for manual reinstatement if required, providing flexibility in the reinstatement process.
What kind of decoupling mechanism exists for RTD signals upon entry into the system?
All RTD signals incorporate high-frequency decoupling to ground upon entry into the system. This decoupling mechanism serves to minimize or eliminate potential noise or interference that could affect the RTD signals accuracy and stability.
