Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
A diode that, above a certain reverse voltage (the zener value), has a sudden rise in current. The voltage across the diode remains essentially constant for any further increase in reverse current, up to the allowable dissipation rating.
Industry:Automation
The maker of a piece of equipment. An example would be a machine tool manufacturer who buys programmable controller components, sensors, and actuators — then integrates them with his machine tool to produce the complete system for sale to the end user.
Industry:Automation
A display of absolute axis position as derived from a position feedback element.
Industry:Automation
A voltage that appears in common at both input terminals of a differential analogue input with respect to ground.
Industry:Automation
The material through which data is transmitted or on which data is stored. Examples of transmission media: twisted pairs, coaxial cables, and optical fibers. Examples of storage media: a disk, volatile semiconductor RAM, and non-volatile ROM. The plural is media.
Industry:Automation
A display that allows temporary storage of data for graphic presentation to the operator.
Industry:Automation
Abbreviated term for armature voltage control of a dc motor, which describes the usual method of changing the speed of a dc motor by controlling the magnitude of applied armature voltage.
Industry:Automation
The maximum level that can be measured. For example, in an analogue input circuit the maximum allowable voltage or current level is called full scale because any increase beyond that level cannot be measured.
Industry:Automation
A drive comprised of the motor, drive controller and operator’s controls (either manual or automatic).
Industry:Automation
Abbreviation for electromotive force. The force that causes electricity to flow when there is a potential difference between two points. Expressed in units of volts. The voltage applied to a motor armature from a power supply is the emf and the voltage generated by the motor is the counter-emf or cemf.
