The IS200TBCIH1CCD is a **Contact Input with Group Isolation board** used within the GE Speedtronic Mark VI and potentially Mark VIe turbine control systems. Here's a breakdown of its functionalities, applications, and where to find more information:

**Function:**

* The IS200TBCIH1CCD interfaces with external dry contact input devices like emergency stop buttons, limit switches, and pressure sensors.
* It has **group isolation**, meaning it electrically isolates different groups of contact inputs to prevent electrical faults or interference from propagating within the system.
* The board typically accepts **24 dry contact inputs** connected to its terminal blocks.
* It converts the voltage changes from these contacts into digital signals that the Mark VI system can understand and process.

**Applications:**

The IS200TBCIH1CCD is used in various applications where the Speedtronic Mark VI system requires monitoring and responding to external contact closures:

* **Power Generation Plants:**  Monitoring safety interlocks, turbine speed switches, and other critical contacts within a power plant.
* **Oil and Gas Industry:**  Integrating emergency shutdown buttons, valve position switches, and other contact-based signals into the Mark VI control system for safe and reliable operation of gas turbines and compressors.
* **Other Industrial Applications:**  Monitoring various contact-based signals from machinery and processes controlled by the Mark VI system across various industries.

**Product Details:**

* **Datasheet and Manual:** GE treats the Mark VI system and its components as critical for safe operation. Publicly available information might be limited. Here are some suggestions for finding resources:
    * **GE Website:** The GE website ([https://www.gevernova.com/gas-power/products/digital-and-controls](https://www.gevernova.com/gas-power/products/digital-and-controls)) might have resources for authorized partners or service providers with access to technical specifications or manuals. Search for "Mark VI Speedtronic" or "IS200TBCIH1CCD".
    * **Authorized Distributors:** Contact authorized GE distributors who might have access to technical specifications and manuals for the IS200TBCIH1CCD specific to your Mark VI system configuration.

**Additional Notes:**

* The IS200TBCIH1CCD works in conjunction with other Mark VI modules for comprehensive control and monitoring.
* Working with the Mark VI system requires qualified personnel due to its complexity and role in ensuring safe and reliable turbine operation.
