Rockwell Automation, Inc. provides industrial automation power, control, and information solutions.
An organisation established to promote development of international standards.
Industry:Automation
A control unit that includes a means of disconnecting an externally operable circuit, motor branch-circuit overcurrent protection, and a magnetic motor controller with associated auxiliary devices (when used). The disconnecting means and motor branch-circuit overcurrent protection consist of a fusible disconnecting device or circuit breaker. If the latter is used, it is either an inverse-time (thermal-magnetic or dual magnetic) or an instantaneous magnetic type circuit breaker. The motor controller includes motor overload protection unless equivalent protection is otherwise provided. Two sets of externally operable circuit disconnection means, each with branch-circuit overcurrent protection and a magnetic motor controller, can be mounted in a single compartment to form a dual unit (as defined in NEMA Standard Pub. No. ICS 2, 1988).
Industry:Automation
A transducer that generates an electrical signal in response to a detected change in light intensity.
Industry:Automation
The distance travelled by light (or other radiation) while completing one complete sine-wave cycle. It is expressed in nanometers (nm). Each colour has a specific wavelength.
Industry:Automation
An organisation under the United States Department of Commerce responsible for developing and disseminating federal standards in many areas.
Industry:Automation
A data storage format that includes the location of the decimal point by expressing the power of the base.
Industry:Automation
A transducer using magnetic coupling to measure absolute rotary position (within one revolution). It generates an analogue output and requires special conditioning electronics.
Industry:Automation
The duplication of devices for the purpose of enhancing the reliability or continuity of operations.
Industry:Automation
Commonly refers to the reading/writing across a link of relatively large blocks of data from one device to another. Whether it is considered an upload or a download may depend upon whether it is a read or write and upon which device initiates the transaction. When data is transferred to a programming or bulk-storage device, it is considered an upload. When data is transferred from a programming or bulk-storage device, it is considered a download.
Industry:Automation
A data table word that does not correspond directly with physical I/O circuits.
