IS210SCLTH1A is a Core Analog Terminal Board manufactured and designed by General Electric as part of the Mark VI Series used in GE Speedtronic Gas Turbine Control Systems. The Core Analog (SCLT) terminal board serves as an invaluable extension for the PCLA module by offering supplementary I/O (input/output) terminals. This expansion allows for a more versatile and comprehensive utilization of the PCLA module's capabilities. The terminal board fulfills the crucial role of managing input signals that are distributed to either one or three PCLA modules. Furthermore, it is also responsible for handling the output signals that have undergone a voting process.


During the installation process, specific provisions have been made to ensure a streamlined and efficient setup for the I/O (Input/Output) cables. Adjacent to the terminal blocks, a designated I/O cable shield terminal is included. This shield terminal plays a crucial role in maintaining the integrity of the signals being transmitted through the I/O cables, safeguarding them from potential interference or disruptions that could compromise the accuracy and reliability of the data being exchanged.

In terms of field device I/O connections, the architecture is meticulously designed for both convenience and practicality. On the SCLS, the system accommodates a total of 72 Euro-style box-type terminal blocks. These terminal blocks serve as essential connection points where field devices are linked to the system. The utilization of Euro-style box-type terminals not only simplifies the process of connecting wires but also contributes to an organized and efficient layout, thereby minimizing the risk of errors during installation and subsequent maintenance.

On the other side of the spectrum, the SCLT side of the system features 48 Euro-style box terminals. These terminals also facilitate the connection of field devices to the system, effectively completing the I/O pathway. The strategic placement and numbering of these terminals help to establish an intuitive and user-friendly interface, enabling installers and technicians to accurately identify and manage the connections.

By employing this thoughtful and well-structured configuration, the installation procedure is enhanced in multiple ways. First and foremost, the segregation of the I/O cable shield terminal ensures that the system's signals remain unimpaired, fostering dependable and accurate data transmission.

The inclusion of a substantial number of terminal blocks on both the SCLS and SCLT sides not only caters to diverse field device requirements but also optimizes the organization and accessibility of the connections. As a result, the installation process becomes more efficient, less prone to errors, and ultimately contributes to a system that is poised for reliable and effective operation.


The module facilitates the distribution of input signals to one or more PCLA modules, employing highly reliable passive circuits that uphold redundancy in critical applications. This meticulous approach ensures consistent and dependable performance even in redundant configurations. To fuel its operation, the module draws 28 V DC power from the interconnected PCLA modules, establishing a cohesive power-sharing arrangement.

To enhance resilience, the power supplies from all PCLA modules are interconnected via diodes, utilizing a Diode-OR configuration. This design strategy effectively aggregates power inputs, creating a redundant power source for the 24 V DC outputs. Each of these 24 V outputs on the SCLT module is equipped with an individual voltage regulator, enriched with thermal shutdown capabilities that act as a safeguard, protecting the branch circuit against potential thermal overload.

In terms of connectivity and interface, the board is furnished with customer-accessible terminals as well as 68-pin connectors specially designed to interface with the terminal board cable. This orchestrated arrangement streamlines the connections and interactions between the SCLT and SCLS components, ensuring a harmonious and cohesive system.

Furthermore, the practicality and user-friendliness of the design are reinforced through the inclusion of forty-eight pluggable Euro-style box-type terminal blocks. These terminal blocks serve as dedicated points for field wire connections. By providing these secure and organized connection points, the module expedites the field wire criminalization process, enhancing the efficiency of both installation and subsequent maintenance activities
