Product Description

8200-1302 is one of the various Woodward 505 digital governors that can be used to control steam turbines. This operator control panel serves as a graphical interface and keyboard, allowing adjustments to the turbine and communication with the turbine. This can be configured through the Modbus communication port on the device. The next generation 505D front panel is equipped with user configurable digital governor control for steam turbines, used for steam extraction and intake control through advanced integrated multilingual interface HMI screens. The new 505D is based on a powerful and reliable standard-setting 505 platform, now globally trusted, with extended communication protocols, intelligent/adaptive control algorithms, and advanced service tools with data logging and RemoteView monitoring capabilities. This model is a low-voltage 18-36 Vdc power input, rated for Class 1, Div. 2 standard position.(http://www.weikunfadacai1.com)

 

8200-1302 has multiple available functions:

Automatic start sequence for hot and cold starts, with temperature input options

Critical speed avoidance on the three speed belt

Ten external alarm inputs

Ten external DI trip inputs

Trip indication for tripping and alarm events with relevant RTC timestamps

Dual speed and load dynamics

Peak speed indication for overspeed tripping

Zero speed detection

Remote droop

Frequency Deadband

The device also provides three normal operating modes, including configuration, operation, and calibration modes.

This device includes two redundant speed inputs and can accept magnetic pickup devices, eddy current probes, or proximity probes. It has analog inputs (8) and can be configured as any of the 27 functions. The device also has an additional 20 contact inputs. The first four of these contacts are used by default for closing, raising speed settings, resetting, and lowering speed settings. Other options can be configured as needed. In addition, the device also has two 4-20 mA control outputs and eight C-type relay contact outputs.

The front panel of 8200-1302 includes emergency trip keys, backspace/delete keys, Shift keys, as well as view, mode, ESC, and Home keys. It also has navigation cross keys, soft key commands, and four LEDs for correlating control and hardware status.
