The GE DS200RTBAG2AFB is a Relay Terminal Board (RTB) module used in GE’s Mark VIe control systems for industrial applications, particularly in power generation systems such as gas turbines and steam turbines. It is part of GE’s suite of components for turbine control and protection.

Product Name:

• GE DS200RTBAG2AFB Relay Terminal Board

Product Description:

The DS200RTBAG2AFB is a relay terminal board that connects and distributes signals between the Mark VIe control system and field devices. This module is designed to interface with relays, sensors, actuators, and other system components. It ensures that electrical signals from the field are properly routed and processed by the control system, allowing for safe and reliable operation of power generation equipment. The terminal board is built with industrial-grade components for durability in harsh environments.

Product Parameters & Specifications:

• Input Voltage: Typically 125 VDC or 250 VDC (depends on configuration).
• Current Rating: Varies based on configuration and load requirements.
• Relay Types: Typically includes electromechanical relays for signal switching.
• Signal Types: Includes discrete inputs/outputs for relay contacts (digital I/O).
• Environmental Ratings: Designed for industrial environments; capable of operating in extreme temperatures (typically between -40°C to 70°C) and high humidity.
• Mounting Type: DIN rail mounting.
• Communication: Typically communicates with the central control system via dedicated communication bus or wiring, such as I/O boards in GE’s Mark VIe or older systems.
• Connectivity: Includes screw terminal connections for easy wiring of field devices (e.g., relays, sensors, actuators).
• Relay Capacity: Depending on the relay configuration, each relay typically handles a variety of control signals, including alarms, trip conditions, and operational commands.
• Design: Designed for high reliability with protection against common industrial electrical faults like overvoltage or short circuits.

Product Use:

• Power Generation Systems: The DS200RTBAG2AFB is primarily used in control systems for turbine control applications (gas turbines, steam turbines, etc.). It serves as an interface between the control system and field devices such as relays and sensors.
• Signal Distribution: It plays a critical role in routing control signals to and from various relays in the field, which is essential for safely operating machinery and ensuring proper protection and control logic execution in industrial power plants.
• Safety and Protection: In power generation systems, this module helps relay control signals that monitor turbine parameters (e.g., temperature, pressure) and engage protective actions when parameters exceed safe limits.
• Remote Monitoring and Control: The module is also used for enabling remote monitoring and control by connecting field sensors and actuators to the central control system, making it essential for operators to manage the operation of power plants from a centralized control room.
