Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
Pertaining to a control that energizes its output when the light intensity on the photodetector reaches a sufficiently high level.
Industry:Automation
1) A device for changing ac to dc. This is accomplished through use of a diode rectifier or thyristor rectifier circuit. 2) A device for changing ac to dc to ac (e.g., adjustable frequency drive). A “frequency converter,” such as that found in an adjustable-frequency drive, consists of a rectifier, a dc intermediate circuit, an inverter, and a control unit.
Industry:Automation
A method of serial transmission where characters may be transmitted at unequal time intervals. It requires that each character contain start/stop timing elements (extra bits) so the receiver can properly detect the start and end of each character. 2) Contrasted with synchronous transmission
Industry:Automation
The signal or signals returned from a controlled machine or process to denote its response to the command signal.
Industry:Automation
A family of configurable ac drives available from the Rockwell Automation Drive Systems Group.
Industry:Automation
1) The portion of a computer or programmable controller that controls the interpretation and execution of the user program stored in memory. 2) The PLC or SLC™ processor.
Industry:Automation
A semiconductor device in which an electric field controls the conductance of a channel under a metal electrode called a gate.
Industry:Automation
Pertaining to a machine constructed in a way to guard against liquid or solid particles falling on it vertically or at a specified small angle (within 15° of vertical) causing interference with satisfactory operation.
Industry:Automation
1) A device or set of devices used to visually present output information. 2) The visual presentation of output information.
