Main Functions

1.Analog Signal Isolation & Conversion: Converts raw field sensor signals (4–20 mA/±10 VDC) into standardized, isolated signals for the control system.

2.Sensor Signal Interface: Connects LVDT/R position, pressure, temperature, and flow sensors to the Mark V turbine control system.

3.Noise Reduction & Data Integrity: Filters common-mode noise and eliminates ground loops to ensure accurate, stable data transmission.

4.System Expansion: Provides scalable analog I/O points for expanding monitoring and control capabilities in Mark V systems.

5.Signal Distribution: Distributes conditioned analog signals to TCQA control boards for real-time turbine regulation and protection.

Application Cases

1.Power Generation: Deployed in thermal power plants for GE Mark V turbine control, monitoring boiler pressure, steam temperature, and generator vibration signals.

2.Oil & Gas: Used in refineries and gas plants for turbine and compressor control, processing 4–20 mA signals from pressure, flow, and level sensors.

3.Petrochemical Industry: Applied in chemical plants for reactor and process monitoring, isolating and transmitting critical analog signals for safety control.

4.Industrial Turbines: Integrated into combined-cycle power plants and cogeneration facilities for GE Mark V gas/steam turbine protection and control.

5.Process Control Systems: Utilized in manufacturing plants for general analog signal conditioning, connecting field sensors to DCS/PLC systems.

Key Features

1.High-Precision Signal Conditioning: ±0.1% FS accuracy ensures reliable measurement of critical process and turbine parameters.

2.Full Galvanic Isolation: 1500 Vrms isolation eliminates ground loops and electrical noise in harsh industrial environments.

3.Multi-Channel I/O: 8 input/8 output channels support simultaneous connection to multiple sensors and actuators.

4.Dual Signal Compatibility: Accepts both 4–20 mA current and ±10 VDC voltage inputs for standard industrial sensors.

5.Seamless Mark V Integration: Direct plug-in compatibility with GE Mark V DS200 rack systems and TCQA core boards.

6.Robust Industrial Design: Coated PCB and high-quality components ensure durability in wide temperature and high-vibration conditions.
