What is DO Digital Output Signal? | Which Instruments Use DO Signals? | DCS Explained Faisal Ahmed

A Digital Output (DO) is a command signal sent from the control system (PLC/DCS) to field devices to perform an action such as OPEN, CLOSE, START or STOP. Faisal Ahmed I&C Engineer In this video we explained DO (Digital Output) signal used in PLC and DCS systems in industrial plants. When the control system sends a DO signal, the field device receives the command and performs the required operation. In this video we also explained which #instruments work on #DO signals in industrial plants. Instruments that use DO #signals: • Solenoid Valve (SOV) • #Motor Operated Valve (MOV) • #Relay • Contactor • #Alarm Horn • #Beacon Light • #Trip Valve • #Shutoff Valve For example: When the DCS sends a @DO @signal to a #Solenoid Valve, the valve energizes and allows air or fluid to operate the actuator. This video is very helpful for: • Instrument Technicians • Fresh Engineers • DCS / PLC learners • Power plant beginners Watch the complete video to understand Digital Output signals in a simple and practical way.
