Woodward 9907-076 Power Supply

This control unit manages steam turbine governing for Woodward systems. You will find the Woodward 9907-1183 Steam Turbine Control regulating speed and load through actuator outputs. Its modular design fits into standard 19-inch industrial control racks.

Technical Specifications

This unit contains one main processor with dedicated I/O circuits. You can also locate two analog output channels for valve positioning. The Woodward 9907-1183 Steam Turbine Control stores no battery energy for program retention. Instead, it uses flash memory for all control algorithms and settings. Therefore, this unit never requires any routine battery replacement.

Control Details

The Woodward 9907-1183 Steam Turbine Control draws its operating power from 24 VDC or 120 VAC supply. You can connect a magnetic speed pickup directly to the dedicated MPU input. The controller executes PID algorithms at 50 Hz for smooth governing response. Moreover, the two analog outputs drive electro-hydraulic actuators for valve control. This design provides precise speed regulation from 0 to 100 percent load.

Mechanical Integration and Mounting

You must mount the Woodward 9907-1183 Steam Turbine Control into a standard 19-inch rack or panel. After positioning, secure the unit using the front panel mounting screws. The unit measures exactly 26.0 centimeters in length and 20.5 centimeters in width. Its total weight reaches approximately 1.65 kilograms for stable rack mounting. Furthermore, the front panel includes LEDs for power, run, and fault status.

Environmental and Storage Guidelines

You should store this Woodward 9907-1183 Steam Turbine Control in a dry location away from conductive dust. The unit operates reliably between -20°C and +70°C ambient temperature. Likewise, keep the unit away from water spray or corrosive atmospheres. Because the unit uses solid-state components only, it requires zero regular maintenance.
