Description Taidacent 20 ST 2s-1000h Time Module, Multifunctional Delay Trigger Delay Relay Chip C005 Delay Chip Taidacent 20 ST 2s-1000h Time Module, Multifunctional Delay Trigger Delay Relay Chip C005 Delay Chip Taidacent 20 ST 2s-1000h Time Module, Multifunctional Delay Trigger Delay Relay Chip C005 Delay Chip Size approximately 12mm * 12mm, operating voltage 2V-5V, delay range can be set from a minimum of 2 seconds to a maximum of 1000 hours, as described below Functions and Design 1. Connect the circuit conforming to the patent requirements and set it to a suitable delay resistor and supply voltage; 2. Before power-on, the output is high level; 3. The trigger signal "falls" means that the trigger output goes low and triggers immediately, simultaneously starting the timer circuit; 4. The timer is set to resume after the output goes high, waiting for the next falling edge trigger signal; 5. The chip will not trigger repeatedly, meaning that if the trigger is invalid, it will not continue to trigger for a period of time after the trigger signal goes low; 6. "Falling edge" triggering refers to the signal changing from high to low instantaneously; 7. Generally, it refers to the high voltage VCC, and the low voltage refers to 0-0.3V or GND, as long as the level requirements are met; 8. The trigger terminal can be connected to a touch screen, microcontroller I/O port, or other digital circuits with falling edge triggering characteristics; 9. The trigger can be designed to trigger only when short-circuited to ground. The current is triggered, the output reaches a high level, and then resumes for a period of time, waiting for the next falling edge trigger. Chip characteristics: 1. Adopts low-power CMOS technology, lead-free and environmentally friendly. 2. Directly pressing outputs a low-level LED (please add a current-limiting resistor), and outputting a high level can drive a transistor (please add a current-limiting resistor). 3. The time can be adjusted via a resistor, with 8 * N (N = 0, 1, 2, 3) times the set time, ranging from 2 seconds to 1000 hours.4. Selectable trigger time and trigger-grounded electronic timer.5. Standby output is high-level, triggered on the falling edge, outputs a low level after triggering, and resets to high level after a delay.
