🛡️ #2oo3D Voting Logic Explained (Two out of Three with Diagnostics)

➡️ In Safety Instrumented Systems (SIS), reliability and fault detection are critical.
➡️ One advanced architecture used in modern safety systems is 2oo3D voting logic.

Let’s break it down 👇

⚙️ What does 2oo3D mean?

➡️ 2oo3 = Two out of Three sensors required to trip
➡️ D = Diagnostics

The system uses three sensors, and at least two must agree before a shutdown occurs, while diagnostics continuously monitor sensor
