Advantages of PLC`s

There are many advantages of PLCs. But some of the main ones are as follows:  The control software is stored locally, so in the event of a building energy management system failure, the PLC can carry on. The connections between the PLC inputs and outputs are made by the software and not by lots of… Continue reading Advantages of PLC`s

PLC Operation.

The basic operation of a PLC is to perform a pre-programmed output, depending on the input signal, by following a set of rules. The PLC completes the following stages in its basic operation. First, there is the input scan, which detects the state of the inputs. Then, the program scan, to see what needs to be done.… Continue reading PLC Operation.

Main Parts of a PLC:

First, we have the input modules or field sensors. These are the physical connections between the outside world and the PLC. These can be: Digital inputs, such as Simple On – Off switches Bi metallic temperature strips Presence or motion sensors Or even a Float switch These digital inputs can only provide information on whether something in… Continue reading Main Parts of a PLC:

PLC Basics Explained

What is a PLC PLC stands for programmable logic controller. There are many variations but they typically look something like this. A Programmable Logic Controller is basically a small computer that can carry out pre-programmed outputs based on inputs and a set of specific rules. They are used in commercial and industrial applications to control… Continue reading PLC Basics Explained

Full Wave Rectifier

We can create a full wave rectifier simply by using a centre tapped transformer and two diodes. A centre tapped transformer just has another wire on the secondary side, which is connected to the centre of the transformer coil, allowing us to use the full length of the transformer or just half of it. Because… Continue reading Full Wave Rectifier
