  • Publication number: 20230047072
    Abstract: An output module for an industrial controller provides electrical isolation between each of the output terminals in the module. The output module receives control signals from the industrial controller indicating a desired output state for each of the output terminals and selectively connects power from the output of the electrical isolation to the output terminal. During normal operation, a switching device connects the power to the output terminal responsive to the control signal. A current sensor monitors the current conducted at the output terminal. If the current exceeds a predefined threshold, a current limit circuit clamps the current being output at the terminal. A control circuit may allow the output terminal to ride through a temporary spike in current or disable the output terminal if a fault condition is detected.

  • Patent number: 11401795
    Abstract: A collar control system and methods for mobile drilling machines are disclosed. One method may include: automatically initiating rotation of a drill bit based on collar settings; automatically feeding the drill bit at a feed rate to form an initial hole at a predetermined reaming increment; and automatically retracting the drill bit from the initial hole when the predetermined reaming increment is achieved, but prior to reaching a collar depth. Another method may include: measuring values of multiple drill bit inputs at a predetermined sample depth region during the collar operation; storing average values for each of the drill bit inputs over the predetermined sample depth region; monitoring values of the drill bit inputs when the drill bit moves beyond the predetermined sample depth region; and ending the collar operation prior to a desired collar depth when any of the monitored values change by a predetermined threshold.
