How a Relay Works - Normally Open vs Normally Closed

✅ Training Program Here - go.beeautomation.co.uk/schema...
What Schematic Specialist will do for you:
Teach you the foundation of electrical controls which is the skill set that underlies all control and automation projects across all sectors giving you a huge amount of project and job opportunities.
Show you how to breakdown and read electrical schematics including relay and contact logic, significantly enhance your fault-finding capabilities, reducing the time to pinpoint and resolve issues and relieve that anxiety we all feel when we lack confidence in our technical ability.
And ultimately give you a big picture understanding of how control and automation are designed giving you the confidence when working on systems out in the field or even if you were thinking about designing your own systems.

Normally Open = OFF when it's not powered (at rest).
Normally Closed = ON when it's not powered (at rest).
In electrical drawings they are represented at rest.
Things get even more interesting with photoelectric sensors, with "light on" or "dark on" modes or when you need to invert the signal in the PLC :)
