Off-Delay Timer An off-delay timer is a type of timer used in electrical and automation systems to delay the turning off (de-energizing) of a load or output after the control signal (input) is removed. ________________________________________ How It Works: 1. Power ON: When the input/control signal is ON, the output is also ON (energized). 2. Power OFF: When the input/control signal is turned OFF, the timer starts counting down. 3. After Delay: Only after the set delay time, the output turns OFF. ________________________________________ Timing Diagram: vbnet CopyEdit Input: ────────────────┐ ┌────────────── └─────────┘ Output: ────────────────┐ ┌────────────── └─────────┘ (delayed off) ________________________________________ Example Use Case: • Fan Delay After Light Off: In bathrooms, a fan might stay ON for 1 minute even after you switch off the light. This is controlled by an off-delay timer. ________________________________________ Key Features: • Starts timing after input signal goes LOW. • Used for post-operation delays. • Common in PLC, relay logic, and industrial automation. #ofdelaytimer #sparkelectric #plc #programming #timer
