Oumefar Timer Relay DC12V Timer Switch Adjustable Timer Relay Module Time Delay Relay Module for Smart Home

Sobre este artículo

• 【Super Material】Made of use electrical and semiconductor components. High structural strength, impact resistance, strong shock resistance, small driving current at the input end can easily interface with various digital programmed circuits.
• 【Safety Protect】Delay time can be adjusted by potentiometer(clockwise to reduce, anticlockwise to increase), default 0-25 seconds, if you need more time, simply replace a larger capacitance or potentiometer.
• 【Functions】Supports on delay and off delay modes, the delay time can be adjusted from 0.1s to 1h, the delay mode and delay time can be set by shorting or opening the jumper pins and rotating the potentiometer.
• 【Triggered Repeatedly】Power supply terminal has anti-reverse diode for Trigger can be high level or low level signals, suitable for industrial control, the module can be triggered repeatedly.
• 【Applications】This module works as a switch with time delay on and off function, highly recommended for automotive circuit modification, and LED lights, DC motors, pump and smart home control system.
