Digital electronics is a branch of electronics that deals with digital circuits and devices. Digital systems are designed to store, process, and communicate information in digital form. 
Digital electronics are based on binary digits 1 and 0, which means that these devices work on only two states: On and Off. Digital electronics are different from analog electronics, which handle continuous voltage and current signals. 

A digital logic controller (DLC) is a device that measures and controls machine operation. It has two digital inputs and two relay output arrangements. DLCs are used in many machines and industries for measurements such as load, pressure, displacement, torque, angle, and vacuum. 

Digital logic circuits can be broken down into two subcategories:
Combinational: Changes instantly, responding to input changes with some delay
Sequential: Adds memory to logical systems 

Microprocessors and microcontrollers are both types of integrated circuits (ICs) that contain a central processing unit (CPU). They have a few key differences:
Microprocessor: A general-purpose IC that can be used in a wide variety of applications. They are often used in high-end electronic devices that require a lot of processing power and memory, such as servers and personal computers.
Microcontroller: A special-purpose IC that is designed for embedded systems. They are often used in embedded systems like home automation, automobiles, and medical equipment. 

Here are some other differences between microprocessors and microcontrollers:
Function: A microcontroller is a complete computer on a chip, while a microprocessor is the brain of a computer.
Components: A microcontroller includes a microprocessor, memory, and components to send and receive data. A microprocessor has more integrated circuit components than a microcontroller.
Energy: A microcontroller uses very little energy.
Speed: A microprocessor has higher clocking speeds up to 4 GHz while a microcontroller can operate with much lower speeds of 200 MHz or less.
Cost: Microcontrollers tend to cost less than microprocessors due to their narrow individual applications and less complexity.
Memory: If you need access to large amounts of really fast memory then a microprocessor is likely your best option. A microcontroller is already embedded with memory so the memory choices are fewer than with a microprocessor.
