Electrical & Temperature Control Systems

About this course

Understand and repair the temperature control loop end to end — thermocouples, solid-state relays and drivers, wiring integrity, and the safety circuits that protect the machine and operator.

What you'll cover

• Control-loop basics
• Thermocouples
• SSRs & drivers
• Wiring
