🚨 What is 2oo3 (Two out of Three) Voting Logic in Safety Systems?

In safety-critical industrial processes, false trips and missed trips can both be dangerous.
To improve reliability and safety, systems often use 2oo3 voting logic.

Let’s break it down simply. 👇

🔹 What does 2oo3 mean?

➡️ 2oo3 = Two out of Three

This means the safety system requires at least two signals out of three sensors to agree before taking an action.

⚙️ How it works
