Equipment and items of industrial automation and control systems (PLC control)

– Types of transducers
A transducer is a device that converts energy from one form to another. Usually a transducer converts a signal in one form of energy to a signal in another.

–Types of sensors and PLC equipment
These sensors supply an ON or OFF signal to the PLC based on whether the condition is met or not, and is usually comprised of solid-state transistors for DC versions or triacs for AC versions. Examples of digital sensors, often used in object detection applications, are photoelectric and proximity sensors.

–Types of timers or time relays
Timing Relays are used extensively in industrial applications, HVAC systems and building services to provide time-delayed switching. For example to start a motor, control an electrical load, or simply automate an action. They play a vital role for targeted logic needs.

– Power supply
A power supply takes the AC from the wall outlet, converts it to unregulated DC, and reduces the voltage using an input power transformer, typically stepping it down to the voltage required by the load. For safety reasons, the transformer also separates the output power supply from the mains input.
