Functional Description

IS230STCC2ASTTC2AG01 is a Simplex Thermocouple Input Board developed by GE. It is part of Mark VIe control system. The Simplex Thermocouple Input (STTC) terminal board is a vital component designed to interface thermocouples with the system. Here's a detailed expansion on its features and specifications: The board is equipped to accept inputs from up to 12 thermocouples. These thermocouples are wired to a Euro-block type terminal block, providing a reliable connection interface for thermocouple wiring.

Features

• Signal Conditioning and Cold Junction Reference: Similar to the larger board, the board features on-board signal conditioning and cold junction reference. This ensures consistency and accuracy in thermocouple measurements, enhancing the reliability and precision of temperature data acquisition.
• Mounting Options: Designed for flexible mounting options, accommodating both DIN-rail and flat mounting configurations. This versatility allows for easy integration into various system architectures and installation setups.
• Compatibility with I/O Pack: Accepts a single I/O pack, enabling additional functionality or expansion capabilities as needed. This scalability ensures that the system can adapt to changing requirements and accommodate future growth.
• Euro-Block Type Terminal Block: The terminal block used on the board is of the Euro-block type, offering a secure and standardized connection interface for thermocouple wiring. This terminal block design facilitates easy installation and maintenance of thermocouple connections.
• Application Specificity: Optimized for simplex applications, providing a reliable solution for thermocouple input requirements in various industrial settings. Its design and features cater to the specific needs of temperature monitoring and control applications.

Product Attributes

• Simplex Configuration: Operates in a simplex configuration, meaning that the board does not offer redundancy in its thermocouple inputs. Simplex systems are typically used when cost efficiency is important, and full redundancy is not required for the application.
• Thermocouple Inputs: This board is designed to interface with multiple thermocouples, which are temperature sensors commonly used in industrial settings. Thermocouples convert temperature into a voltage signal, which the board processes to deliver accurate temperature readings.
• Support for Various Thermocouple Types: The board supports a range of thermocouple types, including types J, K, T, and others. Each thermocouple type has a different temperature range and sensitivity, allowing for flexibility in application. This makes the board versatile for various industrial temperature measurement tasks.
• Cold Junction Compensation (CJC): To ensure temperature accuracy, the board features Cold Junction Compensation (CJC). Since thermocouple measurements are affected by the temperature difference between the measurement point and the reference point, CJC automatically corrects for these variations, ensuring precise temperature readings.
• Diagnostic and Monitoring Capabilities: The board includes self-diagnostic features to continuously monitor the status of each thermocouple input. It detects open circuits, sensor faults, and any irregularities in the thermocouple signals. These diagnostics provide real-time feedback to operators and the control system, allowing for quick identification of issues.
• Analog-to-Digital Conversion: The thermocouple signals, which are initially analog, are converted into digital signals by the board’s internal circuitry. This allows for the temperature data to be processed by the control system, enabling real-time monitoring and feedback control based on temperature variations.
• High Accuracy and Resolution: Offers high-resolution temperature measurement, ensuring that even small temperature changes are accurately captured. This is critical in applications where precise temperature control is necessary, such as turbine management, chemical processing, or furnace operations.
• Simplex Connectivity: The board is typically installed in a simplex system configuration, meaning it is connected directly to the control system without a redundant backup. This makes it a cost-effective solution for applications where a single point of temperature measurement is sufficient.

Plant Data Highway (PDH)

• Connectivity and Applications: The PDH serves as a communication link connecting the CIMPLICITY HMI/data server with remote operator stations, printers, historians, and other customer computers. It enables seamless data exchange and access to plant information across different locations within the facility.
• Media and Data Transfer Speed: The PDH utilizes Unshielded Twisted Pair (UTP) or fiber-optic Ethernet media for data transmission. It supports data transfer rates of 10/100 Mbps, providing fast and reliable communication between devices connected to the network.
• Protocol: Communication within the PDH network is based on the TCP/IP protocol, a widely adopted standard for data transmission over networks. This protocol ensures compatibility, reliability, and efficient data exchange between devices on the PDH network.
• Redundancy and Fault Tolerance: Redundant cables are often required in PDH installations to ensure fault tolerance and uninterrupted operation. Redundancy is essential for critical systems where downtime must be minimized. However, despite redundant cables, the PDH forms a single logical network to streamline management and administration.
• Hardware Components: The hardware infrastructure of the PDH typically includes two redundant Ethernet switches. These switches provide the necessary connectivity and routing capabilities to facilitate communication within the PDH network. Optional fiber-optic outputs may be included to extend network reach, particularly for longer distances to central control rooms or remote locations within the plant.
• Integration with UDH: In smaller systems, the PDH and the Unit Data Highway (UDH) may physically share the same network infrastructure. However, it's crucial to ensure that there is no peer-to-peer control on the UDH to maintain network integrity and prevent conflicts between communication protocols and data traffic.
