GE DS200TCQAG1B DS200TCQAG1BEC RST Analog Input/Output Board
The GE DS200TCQAG1BEC (TCQA) is an RST Analog Input/Output Board integral to the Mark V LM Series, designed for GE Linear Microprocessor Control Systems. As a critical interface between terminal boards and system cores, it processes, adjusts, and routes a diverse range of analog signals, enabling precise control and monitoring of industrial equipment. Its versatility spans handling inputs from LVDTs, thermocouples, vibration sensors, and 4-20 mA signals to outputs for servo valves and relay drivers. It also manages pulse inputs, voltage signals, and generator/line data, with dedicated connectors ensuring streamlined signal flow within the control system.
Key Features:
Comprehensive Signal Handling
The TCQA board excels in processing a wide spectrum of analog and digital signals, making it a linchpin of system connectivity. It processes inputs from LVDTs, thermocouples, vibration sensors, and magnetic pick-ups, while driving outputs to servo valves and relay drivers. It also conditions 4-20 mA signals—critical for parameters like fuel flow and compressor health—and manages pulse rates from TTL signals, ensuring accurate data translation for the control system. This breadth allows it to integrate seamlessly with terminal boards and other core components.
Flexible Hardware Configuration
Hardware customization is enabled via dedicated jumpers: J1 and J2 select milliamp output circuits, while J5 and J6 set output current ranges to match specific equipment requirements. J7 facilitates RS232 port testing, and J8 activates an oscillator for functional checks. This modular design allows on-site adjustments without extensive reengineering, ensuring compatibility with varied operational setups and simplifying maintenance.
Software-Configurable Parameters
Complementing hardware flexibility, software configuration via the I/O Configurator lets users set constants for thermocouple types, pulse rates, vibration thresholds, LVDT/LVDR positions, and 4-20 mA input/output scales. This adaptability ensures the board can be tailored to specific turbine or industrial processes, optimizing signal accuracy and system responsiveness to dynamic operational conditions.
Dedicated Pulse Rate Processing
A specialized circuit handles pulse rate inputs from the TCQC board via the JE connector, processing TTL signals and magnetic pick-up data routed through QTBA/PTBA terminal boards. While the core processes high-pressure shaft speed signals, auxiliary pulse circuits manage additional inputs, ensuring precise monitoring of rotational speeds and related parameters—vital for maintaining equipment efficiency and safety.
Integrated Signal Conditioning & Routing
Beyond processing, the TCQA board scales and conditions signals to ensure compatibility with downstream components. It routes specific signals to the STCA board via the 3PL connector and generator/line data to the TCQC board through JE, creating a structured signal pathway that minimizes interference and ensures data integrity. This integrated approach enhances system reliability by centralizing signal management in a single, robust component.
