Woodward 工业控制产品线目录

The 505CC-2 is a microprocessor-based control with integral application software designed to control a single-valve or two-valve steam turbine and its one- or twostage compressor load. The turbine control architecture is patterned after the popular 505 and 505E turbine controls. The anti-surge control provides the user with a choice between two algorithms—the standard Woodward anti-surge algorithm or a special ‘minimum transducer’ design that adapts to variable molecular weights. Like the 505, the 505CC-2 uses configurable software for maximum field flexibility. The control hardware consists of four plug-together modules housed in a rugged metal chassis. The SmartCore module contains the basic I/O for turbine control. An Analog I/O module interfaces with the signal I/O associated with the one- or twostage load compressor. The main processor and an Ethernet port are located on the Pentium CPU module. In addition, a Power Supply module (24 Vdc) is provided to power the entire control assembly. The modules are stacked into a PC/104 configuration that eliminates the need for a costly motherboard. Connections between the modules are made with plug-together on-board connectors that are environmentally rated for industrial service in adverse conditions. (product spec 03298) 

The Servo Position Controller (SPC) is a servo-valve driver that accepts a DeviceNet or 4–20 mA based position demand signal from a system controller, and accurately positions proportional or integrating servo-valves. The SPC has the required accuracy, responsiveness, and redundancy required for steam or gas turbine fuel valve control. For valve position sensing, the SPC accepts feedback signals from one or two (redundant) ac devices or one dc device. A Windows based software program is used to configure the SPC, adjust tunables, and monitor parameters via a personal computer. For ease of service, SPC configurations can be done while connected or disconnected to the unit. Once a configuration has been created, this program allows configurations to be uploaded and downloaded to other SPCs as desired. (product spec 03254)
