Product Features
GE DS200SDC1G1AGB receives millivolt signals (e.g., J, K, T, E types, etc.), provides cold-junction compensation (CJC), amplifies and linearizes them, and converts them to standard signals (usually voltages) usable by the control system.
GE DS200SDC1G1AGB receives RTD signals such as Pt100, Pt200, Cu10, etc., usually connected in 2/3/4-wire configuration, and provides excitation current/voltage to measure the resistance change, which is converted to a standard signal.
GE DS200SDC1G1AGB can receive standard industrial signals such as 0-10V, ±10V, 0-20mA, 4-20mA, etc. for isolation, filtering and scaling.
GE DS200SDC1G1AGB can generate standard signals such as 4-20mA or 0-10V to drive field actuators (e.g. valve positioners).
GE DS200SDC1G1AGB can receive dry contact (voltage contact) or wet contact (active voltage) signals for isolation, dithering, and status reading.
GE DS200SDC1G1AGB can provide relay contact outputs (usually dry) or transistor outputs to drive indicator lights, relays, small contactors, etc.
GE DS200SDC1G1AGB has built-in protection circuits (e.g. TVS diodes, fuses, current limiting resistors) to prevent over-voltage, over-current, reverse connection, ESD, etc. from damaging the module and the system.
On-board LEDs (usually status lights per channel or group of channels) provide visual diagnostic information on channel operation status, faults, communication status, etc.
Integration of multiple signal channels on a single board (depending on module configuration, typically 8, 16, 32 channels) optimizes rack space utilization.
Some of its features (e.g. input type selection - TC/RTD/AI) may require hardware configuration via on-board jumpers or DIP switches (depending on module variant and firmware).
Configuration is typically performed in strict accordance with GE technical documentation.
GE DS200SDC1G1AGB supports hot-swapping (as allowed by the system and following safety protocols) for easy maintenance and replacement.
Product Applications
GE DS200SDC1G1AGB is dedicated to the GE Mark V gas and steam turbine control systems and is the key interface layer for their data acquisition and control outputs. Typical applications include:
Gas Turbine Monitoring:
Connects key temperature measurement points (e.g., exhaust thermocouples, bearing thermocouples, inter-wheel thermocouples), vibration sensors, flame detectors, pressure transmitters (fuel gas, lube oil, hydraulics), flow transmitters, and position sensors (IGV, valve position).
Gas Turbine Control:
Outputs control signals to fuel control valves, IGV actuators, starter motor contactors, bypass valves, spark plug ignitors.
Steam Turbine Monitoring (Combined Cycle):
Connects steam temperature, pressure, and flow sensors, bearing temperature and vibration sensors.
Auxiliary System Monitoring and Control:
Pressure, temperature, level, switching status monitoring and control outputs for lube system, hydraulic system, cooling water system, fuel supply system.
Protection System Interface:
Inputs critical trip signals (e.g., overspeed, high vibration, high temperature, flame loss) to the protection system (TMR module) via DI.
