The GE IS410TBCIS2C is a safety-rated contact terminal board for the Mark VIe control system. It’s designed to interface with discrete (on/off) input signals, such as from limit switches or emergency stop buttons, in applications where functional safety is critical. The “C” at the end of the part number indicates it is likely coated for environmental protection.
Key Features and Applications
This module stands out because it combines digital signal processing with a high degree of safety and reliability.
- Safety Rating: This is the most crucial feature. A “safety-rated” component means it’s designed to perform a specific safety function, such as initiating an emergency shutdown, even when other parts of the system may fail. It’s built to meet strict standards (e.g., IEC 61508) and provides a highly reliable interface for safety-related inputs.
- Contact Terminal Board: The TBCIS2C designates a terminal board for contact inputs. This means it’s optimized for receiving signals from devices that open or close an electrical circuit, providing a clear on/off signal to the Mark VIe controller.
- Environmental Protection: The “C” in the part number often signifies a conformal coating. This protective layer helps to shield the electronic components from harsh environmental factors like moisture, dust, and corrosive chemicals, increasing the board’s longevity and reliability in tough industrial settings.
The GE IS410TBCIS2C is a critical component in Safety Instrumented Systems (SIS). It is commonly used in industries such as:
- Oil and Gas: For emergency shutdown systems on platforms and refineries.
- Power Generation: To monitor safety interlocks on turbines and generators.
- Chemical Processing: To ensure safe operation of reactors and other process equipment.
It provides a secure and reliable way to connect field safety devices to the main controller, ensuring that safety functions are executed reliably when needed.
