Allen-Bradley is the brand-name of a line of factory automation equipment owned by Rockwell Automation.The company, with revenues of approximately US $6.4 billion in 2013, manufactures programmable logic controllers (), human-machine interfaces, sensors, safety components and systems, software, drives and drive systems, contactors, motor control centers, and systems of such products.
It was founded by Dr. Stanton Allen and Lynde Bradley with an initial investment of $1000. [2] In 1904, 19-year-old Harry Bradley joined his brother in the business, and the company's first patented product, a carbon disc compression-type motor controller for industrial cranes, was demonstrated at the St. Louis World's Fair the same year. In ...
Sequential function chart (SFC) is a visual programming language used for programmable logic controllers (PLCs). It is one of the five languages defined by IEC 61131-3 standard. The SFC standard is defined as Preparation of function charts for control systems , and was based on GRAFCET [ fr ] (itself based on binary Petri nets [ 1 ] [ 2 ] ).
A magnetic starter has a contactor and an overload relay, which will open the control voltage to the starter coil if it detects an overload on a motor. [1] [2] The overload relay opens a set of contacts that are wired in series with the supply to the contactor feeding the motor. The characteristics of the heaters can be matched to the motor so ...

A relay is an electrically operated switch. It consists of a set of input terminals for a single or multiple ...
Today, microprocessor-based relays can perform many protective functions in one device. [1] When one device performs several protective functions, it is typically denoted "11" by the standard as a "Multifunction Device", but ANSI Device Numbers are still used in documentation like single-line diagrams or schematics to indicate which specific ...
