NE555 Time Delay Monostable Switch Module 12V Overview
The NE555 Time Delay Monostable Switch Module 12V is a compact timer relay board based on the NE555 integrated circuit. Designed for 12V DC operation, it provides a single-shot delay from 0 to 10 seconds before energizing its relay contacts, ideal for sequencing and protection tasks.
Key Features of NE555 Time Delay Monostable Switch Module 12V
- Based on the reliable NE555 timer IC for stable monostable operation.
- 12V DC supply with adjustable delay range from 0 to 10 seconds via onboard potentiometer.
- Built-in power indicator LED and timing status LED for visual feedback.
- Relay contacts rated for 250VAC/10A or 30VDC/10A, supporting up to 2200W load.
- Compact PCB design with screw terminals for easy wiring.
- Genuine product with fast shipping across India from Zbotic.
Applications and Use Cases
- Delay-on power sequencing for motors, pumps or compressors to prevent inrush current.
- Vehicle equipment delay for lighting circuits, horn suppression or ignition interlock.
- Control of warning sirens and alarms with precise single-shot time intervals.
- Home automation tasks like stairway lighting or electronic door locks.
- Industrial control panels requiring sequenced actuation of solenoids or valves.
How to Use NE555 Time Delay Monostable Switch Module 12V
Connect a 12V DC supply to the module’s power input terminals, wire your load to the relay output contacts, then trigger the NE555 by applying the start signal (power-up or external trigger). Adjust the onboard potentiometer to set the desired 0–10 s delay; the timing LED will illuminate during the delay and the relay will switch once the interval elapses.
