Introduction to the ControlLogix Power Supply This power supply unit supplies power to the modules in the chassis. It does not normally power field devices, such as lights, solenoids, and motor starters. The power for field devices will typically come from an external source (with some exceptions). There Read More »
Introduction to ControlLogix Output Modules ControlLogix Output modules control equipment. Examples of devices we attach to output modules are solenoids, lights, and motor starters. When the ControlLogix project calls for an output to energize, the status indicator on the module will light. If everything works as it should, a Read More »
Introduction to ControlLogix Input modules ControlLogix input modules read the status of equipment. This could be any type of switch, such as a limit switch when a cylinder extends or retracts to a certain position. Inputs are also used on valves: If a valve is open or shut, Read More »
Introduction to Getting Started with ControlLogix (Industrial Automation) This post is a brief introduction to Getting Started with ControlLogix. The ControlLogix system is an industrial solution for automation. The processor is programmed with RSLogix/Studio 5000. Unlike a regular computer, the ControlLogix processor does not run a normal operating system, Read More »
Introduction to Diode Rectification A diode allows current to flow in one direction. We use diode rectification to convert an AC signal to a DC signal. Another use for a diode is for circuit protection to prevent a reverse polarity connection (+ and – reversed). Just be aware there Read More »
Introduction to Transformer Theory and Ratios Transformer theory describes how a transformer steps voltage up or down in AC (alternating current) circuits. On a transformer, we have primary windings, and secondary windings. The primary winding induces a voltage into the secondary windings that is proportional to the number of Read More »
Introduction to Calculating Power (Watts) If you are not familiar with calculating resistance or current, please visit these posts. This will help you better understand basic electrical principals before trying to calculate power. The Unit of power is the WATT. Power itself is easy to calculate, but we Read More »
Introduction to Calculating Current (Amps) In the last post, we discussed how to calculate resistance. If you are unfamiliar with calculating resistance, please review the post before continuing. In this post, we will learn to calculate current. We talked about a variable resistance being similar to the water faucet Read More »
Introduction to Calculating Resistance (Ohms) In this section, we will be calculating Resistance in series and parallel circuits. A resistor is one of the most basic components of electrical circuits. The unit of resistance is called an Ohm. It’s purpose is to restrict the flow of electrons. To relate this to Read More »
Introduction to the photoelectric resistor The photoelectric sensor can be used to detect the intensity of a light source. This can be used to detect night and day such as you would see in a night light in your house, or a security light on your garage. In industrial applications, Read More »
