What is Di or Do how to work

Question

Accepted Answer

Di and Do are electrical protection devices used in low voltage systems to protect against overcurrent and short circuits.

Di stands for Differential Current Protection and is used to detect and protect against ground faults and leakage currents.
Do stands for Overcurrent Protection and is used to protect against overloads and short circuits.
Di works by comparing the current flowing in the live and neutral conductors, and tripping the circuit if there is a difference indicating a fault.
Do works by detecting the current flowing through the circuit and tripping the circuit if it exceeds a certain threshold.
Both Di and Do are essential components in ensuring the safety and reliability of electrical systems.

Accepted Answer

DI Receives binary On /Off signal from the physical world using for device that have only two states on or off.DO sends binary On/Off signal to control device used to control device that can be ether turned on or off
