GE DS200TCCAG1B TC2000 COMMON ANALOG I/O

The GE DS200TCCAG1B is a specialized circuit board known as a Common Analog I/O board for the TC2000 Common Analog I/O system. It is a key component of the legacy GE Speedtronic Mark V series of industrial control systems, which are used to control turbines in power generation.

Key Features and Function

• Analog I/O Board: The primary function of this board is to manage analog input and output signals. It is one of the essential boards that handle signals from and to the turbine’s sensors and actuators. The “TC2000” designation indicates its use within a specific type of analog control interface.
• Mark V Series: This board belongs to the GE Speedtronic Mark V series, a legacy control system widely used in the power generation industry. The system is known for its high-reliability and fault-tolerant design.
• Obsolete Status: As a component of the discontinued Mark V series, the DS200TCCAG1B 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.
• Purpose: The board receives analog signals from various field devices like pressure transducers and temperature sensors and also sends analog output signals to control devices. This board is crucial for the real-time monitoring and control of the turbine’s operational parameters.
• Conformal Coating: The “B” in the part number often signifies that the board is conformal coated, which is a protective layer applied to the PCB. This coating helps to safeguard the board from environmental contaminants such as dust, moisture, and chemical exposure, which is common in industrial environments.
