Programmable automation controllers (PACs) are process controllers with an open configuration and possessing the enterprise integration power of a PC-based structure. In other words, PACs are industrial controllers that combine the functionality of a programmable … Read more
Edge computing can be defined as a distributed computing framework that brings enterprise applications closer to data sources like local edge servers. In manufacturing, edge computing offers an effective processing and storage choice since intensive data handling and storage can … Read more
Let’s consider a simple three-phase, 480V AC motor control circuit consisting of a contactor, overload block, control power transformer, power fuses or (you may use circuit breakers) and the associated components as illustrated … Read more
RS-485 network is used in many industrial applications to gather data and control addressable motor drives, PLCs, cameras, time clocks, barcode scanners for process control and other factory automatic apparatus.
RS-485 devices can be connected to a computer … Read more
Motor contactors are large, high-current rated electromechanical relays. These are special relays in the sense that, they have heavy duty contacts that can handle the motor’s inrush current over many start and stop cycles. The contactor is actuated by … Read more
A computer is often used as part of a control system. The input data is typically from the operator’s commands and signals from the plant (flows, pressure, temperatures, limit switches, etc.). The output data comes in form of … Read more
The ladder diagram which is a special type of wiring diagram consists of two power rails, which are placed vertically on each side of the diagram, and rungs, which are placed horizontally between the power rails. The power rails are … Read more
Let’s consider the transformer in Figure 1.0 whose secondary winding can be rotated with the respect to the primary winding.
At an angle ϴ, the output voltage will be given by:
Vo = KV… Read more
An actuator is normally controlled by the controller. The actuator, in turn, changes the output of an automated process. The actuator in an automated process may in actual fact be several actuators, each of which provides an output that … Read more
