WOODWARD 8200-4006｜Signal Regulator Board｜
Function
Signal isolation and conditioning
Three terminal electrical isolation (input/output/power), completely blocking ground loop interference
Built in low-pass filter to suppress electromagnetic noise (EMI/RFI) in industrial sites
Signal amplification/attenuation, adapted to different control system interfaces (such as PLC, DCS, speed controller)
Signal conversion
simulation ↔ Simulation: 4-20 mA ↔ 0-10V bidirectional conversion
simulation ↔ Digital: Analog signal to pulse/switch quantity, used for logic control
Pulse shaping: shaping, dividing/doubling the speed/flow pulse signal
High reliability design
Wide temperature range, vibration resistance, and three proof coating, suitable for harsh environments such as power plants, petrochemicals, and offshore platforms
Redundant input/output options enhance system availability
Fault diagnosis output (such as signal overload, disconnection alarm)
Application
Gas/Steam Turbine Control: Signal Conditioning for Speed, Load, and Fuel Valve Position
Generator set control: isolation and conversion of voltage, current, and power signals
Industrial process control: signal processing of flow, pressure, and temperature transmitters
DCS/PLC system interface: signal matching and isolation between different control systems
