5PCS Multifunction Delay Trigger Timing Module IC 2s to 1000h Compact, easy-to-use timing module designed for precise delay control in electronic projects. Each module measures approximately 12 mm x 12 mm and operates from 2 V to 5 V. Timing is adjustable from a minimum of 2 seconds up to 1000 hours, making these modules suitable for short pulses and very long delays. Key benefits - Wide timing range: Configure delays from 2 seconds to 1000 hours to match many applications without complex programming. - Simple trigger interface: Falling-edge trigger input accepts touch switches, momentary buttons, or microcontroller IO pins for straightforward integration. - Reliable one-shot behavior: After a trigger, output stays low for the set delay and will not retrigger until the delay has completed, preventing unintended repeated activation. - Low-power CMOS design: Minimizes standby current for battery-powered systems. - Direct output drive: Output can directly drive an LED or the base of a transistor with a suitable current-limiting resistor for simple load control. - Small footprint: 12 mm x 12 mm size saves PCB space and fits in compact enclosures. Function and operation - Standby output is high. A falling edge on the trigger input starts the timing cycle immediately. - While timing, the module output is low. After the delay elapses, the output returns high and the module awaits the next falling-edge trigger. - Trigger input is compatible with touch switches, microcontroller digital outputs, or other digital circuits that provide a falling edge to ground. - Timing is set by external resistor selection or module configuration, offering multiple selectable ranges to cover 2 seconds through 1000 hours. - Output can switch LEDs or be used to drive transistors; include an appropriate resistor for current limiting. Specifications - Quantity: 5 pieces per pack. - Size: approximately 12 mm x 12 mm per module. - Operating voltage: 2 V to 5 V. - Adjustable timing range: 2 seconds to 1000 hours. - Technology: CMOS low-power design. - Trigger type: Falling-edge trigger, one-shot timing behavior. - Output behavior: Standby high, output low during delay, returns high after delay. Typical applications - Lighting and hold functions: Create delayed turn-off for LED strips, room lights, or indicators after a button press. - Automation and control: Add reliable one-shot delays for relays, motors, or solenoid control in timers, doors, or access systems. - Human interface and debounce: Use with touch or momentary switches to generate a clean, fixed-duration signal for microcontroller inputs or latch circuits.
