⚙️ Industrial Automation Components

These components work together to automate machines and industrial processes.

---

1. PLCs

Programmable Logic Controllers — the brain of automation.
Execute logic, control sequences, and manage machine operations.

2. Sensors

Detect physical conditions: temperature, pressure, position, speed, level, proximity.
Provide real‑time feedback to controllers.

3. Actuators

Convert electrical signals into physical action.
Examples: motors, valves, pneumatic cylinders.

4. HMIs

Human‑Machine Interfaces for operators to monitor and control machines.

5. SCADA

Supervisory Control and Data Acquisition systems for plant‑wide monitoring.

6. Industrial networks

Communication systems like Modbus, Profibus, Profinet, Ethernet/IP.
Enable devices to exchange data reliably.

7. Drives

Variable Speed Drives (VSDs) and soft starters for motor control.
Adjust speed, torque, and starting/stopping behaviour.

8. Robots

Perform repetitive, precise, or hazardous tasks.
Used in assembly, welding, packaging, and material handling.

9. Safety systems

Safety relays, light curtains, emergency stops, safety PLCs.
Protect people and equipment.

10. Power & switching devices

Breakers, contactors, relays, fuses — ensure safe power distribution.
