GE DS200TCCAG1B Analog Input/Output Module

د.إ8,888.00

The $\text{DS200TCCAG1B}$ is a sophisticated microprocessor-based board responsible for scaling, conditioning, and digitizing a wide range of analog field data crucial for turbine operation and protection.

The board is typically located in the R5 core of the Mark V panel.⁴

1. Signal Processing and Conditioning

The TCCA board receives and processes critical sensor inputs from various terminal boards (like ⁵ $\text{TBQA}$ , ⁶ $\text{TBCA}$ , and ⁷ $\text{CTBA}$ ), including:⁸

Thermocouple Inputs: Reads raw thermocouple data, and uses the cold junction reference provided by the terminal boards to calculate the compensated, actual temperature value.⁹
RTD Inputs (Resistance Temperature Detectors): Provides excitation current to the ¹⁰ $\text{RTDs}$ and then measures, calibrates, and scales the resulting voltage signal to determine the temperature.¹¹
$4-20\text{ mA}$ Current Loops: Reads ¹² $\text{4-20 mA}$ input signals from remote transmitters (transducers) and drives ¹³ $\text{4-20 mA}$ output signals to remote monitoring instruments.¹⁴
Shaft Monitoring: Handles the processing of sensor signals related to turbine shaft voltage and shaft current.¹⁵

الوصف

The GE DS200TCCAG1B is a Common Analog I/O Board (TCCA) that functions as a core data processor for analog signals within the GE Speedtronic Mark V Turbine Control System.¹

The “B” in the part number indicates a functional revision to the original ² $\text{DS200TCCAG1A}$ board, generally meaning it has minor enhancements or fixes while maintaining the same overall functional role.³

🔬 Core Functionality

The board is typically located in the R5 core of the Mark V panel.⁴

Shaft Monitoring: Handles the processing of sensor signals related to turbine shaft voltage and shaft current.¹⁵

2. Data Transfer and Architecture

Microprocessor: The board contains an 80196 microprocessor and multiple PROM modules (Programmable Read-Only Memory) for firmware and configuration instructions.¹⁶
Data Bus: Conditioned data is sent from the TCCA board to the main ¹⁷ $\text{I/O}$ Engine (¹⁸ $\text{STCA}$ board) via the 3PL connector, which acts as a data bus to the rest of the control system.¹⁹

🧩 Hardware & Configuration

The board’s physical assembly and configuration allow it to interface and be configured specifically for the application:

Component	Purpose
3PL Connector	Main data path to the $\text{STCA}$ board (I/O Engine).
JCC & JDD Connectors	$\text{50-pin}$ connectors primarily used to receive RTD signals from the $\text{TBCA}$ terminal board.
Jumpers ( $\text{J1, JP2, JP3}$ )	Configurable hardware jumpers (typically three) are used to set board functions, such as enabling/disabling the $\text{RS232}$ serial port for testing. Jumper settings must be matched when replacing the board to maintain system configuration.
LED	A single $\text{LED}$ is provided for status indication.

The DS200TCCAG1B is essentially the newer version of the ²⁰ $\text{TCCA}$ board, ensuring continued analog signal reliability in the ²¹ $\text{Mark V}$ system.²²
