Core Functions

1. Multi‑type Field Analog Signal Conditioning & Acquisition This board is the core analog input/output interface for Mark‑V R/S/T redundant control cores. It receives and conditions diverse field signals: thermocouple, 4‑20 mA transmitter signal, LVDT position feedback, vibration sensor input, pulse frequency signal, and generator‑line analog measurements. It completes signal filtering, scaling, cold‑junction compensation for thermocouples, and analog‑to‑digital conversion, converting raw field analog values into standardized digital data for turbine main processor.
2. Analog Output Drive for Field Actuators Delivers analog drive output for servo valves and proportional actuators, implementing closed‑loop control for fuel valves, governor actuators and other critical turbine‑related field devices. Digital control commands from main CPU are converted into stable analog drive signals by on‑board DA conversion circuit.More products: www.plcva.com

General Electric DS200TCQAG1B RST Analog‑I/O Processor Circuit Board

1. Core‑bus High‑speed Data Interaction Installed as plug‑in board inside Mark‑V control cabinet. It communicates with other core boards (STCA, TCQC etc.) via multi‑pin backplane connectors and CoreBus data bus. It uploads processed field‑acquired data to main controller, meanwhile receives down‑loop control setpoints from system processor for actuator output execution.
2. On‑board Hardware Diagnostics & Status Indication Equipped with 6 front‑view LED indicators for board power status, data‑processing activity and hardware fault alarm. Built‑in self‑test circuit monitors board hardware health, channel abnormal status and communication‑link errors. Detected faults will be reported to Mark‑V system for event logging and interlock trigger. Jumpers on PCB support hardware configuration adapting to different turbine application modes.
3. Industrial Conformal‑coated Rugged Hardware Design Conformal coated PCB for anti‑humidity, anti‑corrosion and anti‑interference in power‑plant harsh environment. Multiple 34‑pin & 40‑pin connectors provide abundant field‑wiring interfaces. It runs inside triple redundant R/S/T control cores to enhance overall system reliability for turbine safety‑critical control.
4. Redundant‑core cooperative operation Normally deployed in R, S, T three redundant cores of Mark‑V system. Three boards execute parallel signal acquisition and processing; system performs voting logic on multi‑channel sampling data to avoid single‑board failure causing turbine mis‑operation, realizing TMR high‑reliability control architecture.plcva.com

General Electric DS200TCQAG1B RST Analog‑I/O Processor Circuit Board

Applications & Purposes

DS200TCQAG1B is legacy dedicated internal I/O processor board for GE Speedtronic Mark‑V gas‑turbine & steam‑turbine control system; it cannot operate independently and must cooperate with matched Mark‑V rack hardware and firmware.

Typical Application Industries ‑ Thermal power plants: gas‑turbine combined‑cycle units, steam‑turbine generator sets ‑ Oil & gas, petrochemical plants: large‑turbine driven compressor packages ‑ Refineries, chemical heavy‑duty power‑generation equipment ‑ Heavy‑industry on‑site turbine‑control system lifecycle‑extension retrofit projects

Main Purposes

1. Collect key process parameters of turbine unit: temperature, pressure, flow, vibration, valve‑position feedback and generator‑electric‑parameters, serve as signal front‑end for turbine closed‑loop control.
2. Output analog control signals to drive fuel‑servo valves and governing actuators, realize turbine speed‑regulation, load‑control and combustion‑process adjustment.
3. Complete signal exchange between field sensors/actuators and Mark‑V main control processor, act as critical signal‑bridge between field layer and control core.
4. Cooperate with R/S/T triple‑modular‑redundant architecture to improve anti‑failure capability of turbine control system, guarantee safe and stable operation of power‑generation units.
5. Serve as OEM spare‑part replacement for existing aging Mark‑V racks; restore analog‑I/O channel function after original board failure for running power‑plant equipment.
