Functional Description
IS200SCLSH1A is a core analog terminal board designed and developed by GE. It is a part of Mark VIe control system. The Core Analog Terminal Board serves as the interface for routing terminals and signals to the BCLA board. It accommodates various inputs, including eight thermocouple inputs, four analog inputs, and eight RTD inputs. Each of the four 4-20 mA inputs has its dedicated 24 V dc power source. The output channel delivers a single 4-20 mA simplex output signal. To facilitate field wire connections, there are a total of seventy-two pluggable Euro-style box-type terminal blocks. These terminal blocks are organized into three sets of 24 terminals each, providing convenient access points for field wiring.
Installation
- The installation process involves more than just the connection of terminal blocks. Included in the setup is an I/O cable shield terminal, specifically designed for this purpose. It's crucial to note that certain terminal points, namely 23, 24, 43, 44, 45, 46, 47, and 48, are intentionally left unconnected as part of the installation configuration.
- Regarding the field device input/output (I/O), connectivity occurs through 72 Euro-style box terminals positioned along the edge for one section and an additional 48 Euro-style box terminals situated on the SCLT edge for another section. These terminals facilitate the interface and interaction between the field devices and the system, enabling seamless data transmission and operation.
Operation
- During the operational phase, the primary function of the terminal board is to oversee and manage the customer terminals while effectively directing signals to the BCLA (Board for Control and Analog processing). This process ensures the efficient transmission of signals and data between various components within the system.
- To facilitate connectivity, SCLS (presumably a system or manufacturer) offers J2 connectors equipped with 68 pins, specifically designed for the terminal board cable. These connectors serve as the interface between the terminal board and its associated cables. The terminal board, housed within the module, is responsible for the organized transmission of signals, efficiently directing them towards the connectors linked to the BCLA analog processing board.
- For wiring connections from field devices, the setup incorporates 72 pluggable Euro-style box terminals. These terminals are structured into three distinct sets, each comprising 24 terminals. This grouping simplifies organization and management, streamlining the process of connecting field wires to the system for data exchange and functionality.
Thermocouples
- Thermocouples are vital sensors accepted by the PCLA (Presumably a component or system) in various types, including E, J, K, S, and T, along with mV inputs. SCLS (the system or entity) facilitates the termination of simplex inputs originating from the field, catering to eight thermocouple inputs configured in a simplex manner.
- To integrate these thermocouples seamlessly, a direct connection of the thermocouple wires to the thermocouple I/O terminal blocks is required. These terminal blocks, designed for easy removal, are affixed to the terminal board using two screws, ensuring a secure and reliable connection.
- The eight thermocouple inputs can be configured as either grounded or ungrounded, providing flexibility based on system requirements. These inputs maintain a maximum two-way cable resistance of 450 ohms and can be positioned up to 300 meters (984 feet) away from the turbine control cabinet, allowing for extended placement while retaining functionality.
- The SCLS terminal boards encompass a cold junction reference device, essential for accurate thermocouple measurements, along with provisions for high-frequency noise suppression. Additionally, the crucial tasks of analog-to-digital conversion and linearization, tailored for individual thermocouple types, are efficiently managed by the I/O processor. This processing capability ensures precise and reliable interpretation of the thermocouple inputs, optimizing their functionality within the system.
