GE DS200TBQAG1A TERM.BD (C)R-S-T TC I/O

الوصف

The GE DS200TBQAG1A is a specialized circuit board known as a Terminal Board for the Mark V series of turbine control systems. Its primary function is to serve as a termination point for thermocouple (TC) signals.

Key Features and Function

• Thermocouple I/O: The board is specifically designed to handle thermocouple inputs. These sensors measure temperature and are critical for monitoring various points on a turbine. The board’s designation “(C)R-S-T TC I/O” indicates that it works with the triple-redundant (R, S, and T) processors of the Mark V system to manage these thermocouple signals.
• High-Density Connectivity: The board features two 90-pin terminal blocks to support up to 180 signal wires. This allows for the consolidation of numerous thermocouple inputs onto a single board, which is essential for managing the vast number of sensors in a turbine control system. It also has three 20-pin connectors for interfacing with other components in the control cabinet.
• Cold Junction Compensation: The board includes a circuit for cold junction compensation. This is a crucial function for thermocouples, as it corrects for the temperature of the reference junction, ensuring that the temperature reading is accurate.
• Mark V Series: This board is an integral part of the GE Speedtronic Mark V series, a legacy control system widely used in power generation for controlling gas, steam, and wind turbines. The system is known for its high-reliability and fault-tolerant architecture.
• Obsolete Status: As a component of the discontinued Mark V series, the DS200TBQAG1A is considered an obsolete part. It is no longer manufactured by GE and is typically sourced from new old stock, surplus vendors, or specialized repair and refurbishment companies.
