Description
A compact, high-precision monostable delay timer based on the classic NE555 IC. When triggered, it activates the onboard relay for a user-set interval (typically 0–10 seconds, adjustable via potentiometer or external R/C) before automatically resetting.
Key Features:
Monostable Delay Operation: Triggers once per input pulse; output stays active for a defined period (~0–10 s) before auto-reset.
High Current Relay Control: Relay contacts rated up to 10 A, supporting AC (250 V) or DC (30 V) loads—handling up to ≈2200 W.
LED Indicators: Displays power-on state and timing phase, enabling clear visual feedback. Solid Temperature Stability: NE555’s timing accuracy stable at ~0.005%/°C.
DELAY MONOSTABLE SWITCH MODULE
Compact size and plug-and-play design allow easy integration into both DIY electronics and professional control systems using popular UNO/Rduino-compatible platforms.
Equipped with a high-quality NE555 IC for stable and reliable monostable operation, allowing consistent timing and output control in circuits.
