Description
WOODWARD 8402-319 Functional Features: Startup and Detection Functions: It has an automatic startup sequence for both hot startup and cold startup, with a temperature input option; it also has a zero-speed detection function. Speed and Load Control: Critical speed avoidance can be achieved on the three-speed band; it has dual-speed and load dynamic functions. Alarm and Trip Functions: It is equipped with ten external alarm inputs and ten external DI trip inputs; there is a trip indication for trip and alarm events with relevant RTC timestamps. Operation Modes: It provides three normal operation modes, namely configuration mode, operation mode, and calibration mode. Input and Output Configuration: It includes two redundant speed inputs, which can accept magnetic pickup devices, eddy current probes, or proximity probes; there are 8 analog inputs that can be configured for any of the twenty-seven functions; there are also 20 contact inputs, among which the first four are defaulted for shutdown, increasing the speed set value, resetting, and decreasing the speed set value; in addition, it has two 4 - 20 mA control outputs and eight Type C relay contact outputs. Panel Design: The front panel includes an emergency trip key, a backspace/delete key, a Shift key, as well as view, mode, ESC, and Home keys. It also has a navigation cross key, soft key commands, and four LEDs for indicating the associated control and hardware status. Technical Parameters: The control type is microprocessor-based PID control; the input voltage has different specifications such as low voltage 18 - 36 VDC isolation; the communication interface supports multiple methods such as analog, digital, and serial; the operating temperature range is from -22°F to 158°F. Application Areas: It is widely applied in fields such as petrochemical, power, pharmaceuticals, food processing, tobacco, and building automation, etc., to achieve precise control of motor speed and motion control.
