PLC HARDWARE WIRING DIAGRAM
Introduction and Basic Parts of Ladder Diagram in PLC
Aug 19, 2018In the ladder diagram, the programming language that used to create the program to control the PLC system is known as ‘Ladder Diagram Language’ or ‘Ladder Logic Language‘. It has signified by the graphical representation, just like electrical wiring for logic control.

Nov 27, 2018PLC Wiring Basics. If you are still a little confused about the different PLC wiring and ladder diagram symbol combinations and their different logic states then’T PANIC! To help out we’ve developed a nifty table which displays the different combinations of PLC digital input wiring and ladder logic symbols that can be used.
Programmable logic controller - Wikipedia
A programmable logic controller (PLC) or programmable controller is an industrial digital computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis. Dick Morley is considered as the father of PLC as he had invented the first
Programmable Logic Controllers (PLCs): Basics, Types
Jul 13, 2019This is where a programmable logic controller comes into the picture, which doesn’t require any additional wiring and hardware to make sure of a change. Rather it requires a simple change in code, programming the PLC to only turn on the light 30 seconds after the switch is turned ON.
13 Main Difference between PLC and Relay Based Controller
Apr 22, 2019If we compare the relay with PLC, PLC systems perform better in terms of work, accuracy. PLC requires less time, less wiring. PLC is easy to maintain. There will not be much physical work. PLC has more advanced functions as compared to manual work (hardware relay-base).

Programmable Logic Controllers (PLC) | Ladder Logic
Before the advent of solid-state logic circuits, logical control systems were designed and built exclusively around electromechanical relays. Relays are far from obsolete in modern design, but have been replaced in many of their former roles as logic-level control devices, relegated most often to those applications demanding high current and/or high voltage switching.
Schematic - Wikipedia
A schematic, or schematic diagram, is a representation of the elements of a system using abstract, graphic symbols rather than realistic pictures. A schematic usually omits all details that are not relevant to the key information the schematic is intended to convey, and may include oversimplified elements in order to make this essential meaning easier to grasp.

Inside the PLC housing, connected between each input terminal and the Common terminal, is an opto-isolator device (Light-Emitting Diode) that provides an electrically isolated “high” logic signal to the computer’s circuitry (a photo-transistor interprets the LED’s light) when there is 120 VAC power applied between the respective input terminal and the Common terminal.
Programmable logic controllers (PLC)
The easyE4 is the world’s premier nano programmable logic controller (PLC). Containing 12 I/O with the capability to be expanded to a network of up to 188 I/O points. The XC300 small PLC is scalable utilizing the XN300 modular I/O platform, the XC300 shines in highspeed applications that demand the highest degree of programming flexibility.
