Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
An I/O module that contains circuits that convert analog dc input signals to digital values that can be manipulated by the processor. By implication, these analog inputs are usually direct (i.e., a data table value directly reflects the analog signal value).
Industry:Automation
1) For a computer, a CRT terminal or printer. 2) For a programmable controller, see actuator
Industry:Automation
A program written in a format similar to a relay ladder diagram.
Industry:Automation
In paint programs, a collection of drawing tools, such as geometric shapes, patterns, colors, brush shapes, and line widths, from which the user can choose.
Industry:Automation
Units of measurement (such as pounds, pounds per square inch, degrees Celsius) relative to the process. An input signal is often a percentage of the full-scale range (such as ±5 Volts, or 4–20mA) of direct measurement that must then be converted, through scaling, into engineering units. See scaling
Industry:Automation
An I/O module that contains circuits that convert dc signals from a machine/process switching device to backplane logic level dc signals. By implication, they are direct digital inputs.
Industry:Automation
Operation at a substantially constant load for an indefinite duration. Most commonly used in the context of a continuous-duty current rating. Often expressed simply as “continuous.”
Industry:Automation
1) A control system that has no means of comparing a feedback input to a command generating the output control signal. One example of an open-loop system is one with a stepper-motor output. 2) Contrasted with closed-loop system
